DEV Community: CometChat

News Roundup: Compute got scarce. Efficiency stopped being optional.

AI That Finds Its Own Zero-Days

What's going on?
OpenAI launched GPT-6 Astra - the first model that can independently discover and exploit unknown software vulnerabilities, and it's pairing that with $1B for cyber defenders.
Why it matters
Attackers get frontier tools the day they ship. Now defenders do too but only if they move first. The gap between ‘we should patch that’ and ‘someone already did’ just got shorter.
What we think at CometChat
Same story we know well: capability without accountability breaks things at scale. Powerful AI agents - in security or in chat need guardrails built in, not bolted on later. Ship fast, but ship safe.

Samsung and Arm Build 2nm AI Chip

What's going on?
Samsung and Arm kicked off a custom 2nm chip built to run AI directly on your device with OpenAI rumored to be the end customer.
Why it matters
On-device AI means less round-tripping to the cloud. Lower latency, less dependence on someone else's servers, and inference that happens where your users actually are.
What we think at CometChat
The whole industry is quietly moving intelligence closer to the edge. For chat and AI agents, that's the good direction - faster responses, private by default. The interesting part isn't the silicon. It's what you build on top of it.

Chip Gear Spending Hits Record $40B

What's going on?
Semiconductor equipment billings hit a record $40.53B last quarter - the second record in a row as chipmakers race to build capacity for AI.
Why it matters
Memory is booked solid through 2027, and new capacity won't land before 2028. Translation: the compute powering your AI features is getting pricier and scarcer, not cheaper.
What we think at CometChat
When infrastructure is this constrained, efficiency stops being optional. For AI agents and chat at scale, every wasted call costs real money. The teams that win won't be the ones with the most compute - they'll be the ones who waste the least.

$3.5B Bet on Humanoid Robots

What's going on?
Nscale is committing $3.5B in compute (scaling to $6B+) to power Figure's humanoid robots 100,000 Nvidia GPUs, plus an equity stake in the robotics startup.
Why it matters
Physical AI is getting real money and real infrastructure. Robots that learn, adapt, and operate in the world all run on the same thing your software does: massive, expensive compute.
What we think at CometChat
The line between ‘AI in an app’ and ‘AI in a body’ is thinner than it looks. Both need the same foundation - models that respond fast and reliably. Whether it's a robot in a warehouse or an agent in a chat, the hard part was never the demo. It's making it work every time.

Xiaomi Debuts Its Own 3nm Chips

What's going on?
Xiaomi unveiled three in-house chips at IFA - a 3nm flagship phone SoC, an edge AI accelerator, and an autonomous driving chip reducing its reliance on Qualcomm and MediaTek.
Why it matters
When a company owns its silicon, it controls the whole stack - performance, power, and how AI runs on-device. That's tighter integration and less waiting on someone else's roadmap.
What we think at CometChat
The edge AI chip is the one to watch - 330 tokens per second, running inference right on the device. As more intelligence moves on-device, chat and AI agents get faster and more private by default. The demo is easy. Owning the whole pipeline is the hard, smart part.

Google Recycles Old Chips to Survive

What's going on?
Google is pulling DDR4 memory from retired servers and adapting it for new AI machines - a stopgap as the memory shortage bites and prices climb up to 90% in a quarter.
Why it matters
Even the biggest players can't buy their way out of this. Memory now eats ~30% of hyperscaler budgets, up from 8% two years ago. The cost of running AI is being reshaped by a shortage that lasts through 2030.
What we think at CometChat
Efficiency just became a survival skill. When compute and memory are this scarce, the winners aren't the ones spending the most - they're the ones getting more out of less. For AI agents and chat at scale, lean beats lavish. Every wasted call has a price now.

News Roundup: The frontier moved from "can it?" to "can you trust it?"

Gemini Now Runs Your Tasks Solo

What's going on?
Google gave Gemini Live an agentic upgrade - you speak a goal out loud, and it runs multi-step tasks across Docs, Sheets, Gmail, and Drive on its own.
Why it matters?
Voice stops being just Q&A. Assistants now remember your intent and act on it for days - no app-switching, no babysitting the workflow.
How we see it at CometChat
This is where conversation becomes the interface. The hard part isn't making an agent talk, it's making it act reliably across a real product. Agents are only as good as the messaging layer they run on.

Nvidia's Robots Just Hit $10 Billion

What's going on?
NVIDIA's physical AI arm - chips for robots, self-driving cars, and drones now pulls in ~$10B a year, with China shipping 97% of the world's humanoid robots.
Why it matters?
The ‘ChatGPT moment’ for robots isn't coming - Huang says it already passed. Physical AI is scaling from demos to factory floors, fast.
How we see it at CometChat:
A robot that moves is impressive. A robot you can actually talk to, that understands context and responds in real time - that's the harder problem. Intelligence in hardware still needs a conversation layer that doesn't fall over.

Meta's New Agent Shops, Books, and DJs

What's going on?
Meta is testing ‘Project Hatch’ - a personal AI agent with its own computer that books restaurants, orders food, buys gifts, and even runs your Spotify, all in the background.
Why it matters?
Agents are moving from answering questions to taking actions across your real apps and accounts - email, calendar, OpenTable, DoorDash. The interface is becoming a delegate.
How we see it at CometChat
Handing an agent your calendar is easy. Handing it your conversations is where trust gets real. When agents start acting on your behalf, the messaging layer has to be reliable, secure, and legible because ‘it booked the wrong thing’ is a much bigger problem in production than in a demo.

Google's AI Video Now Directs, Not Just Generates

What's going on?
Gemini Omni 1.1 Flash adds 4K upscaling, keyframe transitions, and scene extension up to 40 seconds giving AI video an actual beginning, middle, and end.
Why it matters?
The pitch shifts from ‘generate a clip’ to ‘direct a scene.’ Cheap 360p drafts, polished 4K finals - a workflow real production teams can actually use.
How we see it at CometChat
Every leap in AI-generated content raises the same question: how do people talk about it, react to it, share it? Richer media only matters if the room around it - comments, threads, live reactions can keep up. The content gets better; the conversation layer has to too.

AI Guides World-First Brain Tumour Surgery

What's going on?
Surgeons in London removed a brain tumour using real-time AI that colour-coded critical vessels and nerves on a live video feed - saving a 48-year-old's eyesight.
Why it matters?
AI as an ‘expert second pair of eyes,’ trained on more operations than a surgeon sees in a lifetime. Not replacing the human rather assisting the highest-stakes decisions in real time.
How we see it at CometChat
The surgeons kept full control the whole way - the AI advised, humans decided. That's the model that works. Whether it's an operating theatre or a support chat, the best AI doesn't take over the conversation. It gives people better information at the moment they need it, and lets them make the call.

Hyundai Bets Big on Self-Driving by 2028

What's going on?
Hyundai and NVIDIA are teaming up to put Level 2+ self-driving in mass-market cars by 2028, backed by a 50,000-GPU data centre and an in-house AI system.
Why it matters?
Self-driving stops being a luxury demo. When 12 of every 20 new cars in China already ship with Level 2+, autonomy becomes a standard feature buyers expect, not a moonshot.
How we see it at CometChat
Hyundai's whole bet is the ‘data flywheel’ - collect, train, deploy, repeat. Same logic applies to how products talk to users: every conversation is a signal. The teams that win aren't just shipping AI features, they're building the feedback loop that makes each interaction smarter than the last.

CometChat Cards

CometChat — Thu, 03 Sep 2026 08:15:47 +0000

Most of what people send each other in a chat isn't really a sentence. Someone shares an event, and the date, location, and RSVP link should travel together. A group admin posts an announcement that deserves more than a wall of text. A friend drops a link that needs a clear next step attached, not just a bare URL. In a 1:1 or group conversation, all of that gets squeezed into plain text, because there's never been a way to send something more structured than a message bubble.

CometChat Cards fixes that. A card carries a block and renders natively, as images, buttons, and layouts, right inside the same 1:1 or group chat window a text message would appear in.

Why does this matter to me as a developer building chat experiences?

Every custom message type you've ever built for a chat app followed the same path: design the payload, write a renderer for it, wire up the actions, repeat for the next one. It doesn't scale past the first few designs, and every platform you support means doing it again.

CometChat Cards take that off your plate. Design a card once, visually, in the CometChat Dashboard, and every UI Kit that supports the format renders it the same way, no custom parsing required.

Key features and capabilities

Card Builder, a visual editor in the Dashboard.
Build cards from 20 elements across four groups: content (text, markdown, image, icon, avatar, badge, chip, code block), layout (row, column, grid, accordion, tabs, divider, spacer), interactive (button, icon button, link), and data (table, progress bar). Four elements, button, icon button, link, and chip, can carry an action, and there are nine kinds to choose from: open a URL, start a chat with a user or group, send a message, copy to clipboard, download a file, initiate a call, hit an API, or run a custom callback in your app.
Nine starter components.
Product Card, Order Confirmation, Order Tracking, Event Card, Announcement, Quick Reply Buttons, Feedback, Data Table, and Carousel come pre-assembled, so you're editing instead of building from a blank canvas.
Variables
Insert placeholders like {{user.name}} anywhere in a card's text or URL fields, and CometChat fills them in per recipient when the card sends.
Built into every UI Kit.
Card messages are rendered automatically across all CometChat UI Kits. When a card message appears in a conversation, the UI Kit detects it and displays the appropriate card interface without any additional setup.
No wiring required
Card messages are handled internally by the UI Kit, so they work out of the box in CometChatMessageList and other standard conversation views across all supported platforms.
Fallback text
Every card includes fallback text. If the card JSON is malformed or a client doesn't support cards yet, the UI Kit falls back to that text instead of showing nothing, so the message still says something.

Where this shows up

CometChat already builds for these industries. Card Builder's starter components map onto what's already happening in each one's 1:1 and group chats:

Marketplace
A buyer and seller are already negotiating a listing in 1:1 chat. A Product Card carries the photo, price, and condition inline instead of the buyer switching to a listing page, and an Order Confirmation card closes the loop once they agree.
On-demand services
Customer and provider are coordinating a job in real time. An Order Tracking card shows live status and ETA right in the thread, the same conversation where they're already discussing pickup details or a delivery photo.
Education
A teacher posts to a class group chat. An Announcement or Event Card carries a session time, a join link, and an RSVP button, instead of the group scrolling past three separate messages to piece it together.
Gaming
A clan or guild group chat gets patch notes, a Data Table of leaderboard standings, or a Carousel of upcoming tournaments, laid out the way a status update actually reads instead of a wall of patch numbers.

Healthcare
A patient and provider are messaging 1:1. An Event Card carries an appointment time with a reschedule button attached, or a Feedback card collects a quick check-in after a visit, without either side leaving the thread.
Dating
Two matches are talking. Quick Reply Buttons turn a common question into a tap instead of a typed reply, and a Carousel can surface shared interests or icebreaker prompts inline.
Community and social.
A group admin drops an Event Card for a meetup with an RSVP action, or an Announcement card for a rule change, so it reads as distinct from the conversation instead of getting lost in it.
SaaS businesses
A workspace or support channel gets a Data Table showing open ticket status, or an Announcement card for a new feature, sent to a group the same way any other message would be, just structured.

Frontend Actions for AI Agent Builder

CometChat — Fri, 13 Mar 2026 08:30:31 +0000

We're excited to introduce Frontend Actions for CometChat's Agent Builder. This new capability transforms your AI agents from purely conversational interfaces into interactive drivers of your application's UI, enabling them to trigger client-side behaviors like opening modals, navigating to pages, showing notifications, and executing custom functions directly in response to user conversations.

With Frontend Actions, your agents can now do more than just talk - they can act. Instead of telling users where to go or what to do, agents can guide them there, opening the right dialog, navigating to the correct page, or triggering the appropriate workflow based on conversational context. All of this happens seamlessly through your existing UIKit components, with no additional infrastructure required.

Why does this matter to me, as a developer?

As you build AI-powered chat experiences, static text responses often fall short of creating truly helpful user journeys. Users frequently need more than information - they need action. Without a structured way to bridge conversation and UI, you're left manually building complex routing logic or asking users to navigate on their own after receiving guidance.

Frontend Actions helps you:

Enable agents to drive user workflows by triggering UI interactions directly from conversation context.

Eliminate the gap between agent recommendations and user actions with seamless handoffs to modals, forms, or other UI elements.

Maintain clean architecture by keeping action handlers in your client code while letting agents decide when to invoke them.

The result is more intuitive user experiences, reduced development overhead, and agents that feel like natural extensions of your application instead of bolted-on chatbots.

Key features and capabilities

Client-side behavior triggers

Define actions that agents can invoke to open modals, navigate pages, display notifications, pre-fill forms, or call any custom function in your application. Agents determine when to trigger these actions based on conversational context, turning passive responses into active guidance.

Flexible action configuration

Each Frontend Action requires:

A display name for dashboard clarity
A description that teaches the agent when to use it
A trigger function identifier your client app recognizes
Optional parameters to pass contextual data.

This configuration lives in the Agent Builder dashboard, keeping your action definitions centralized and version-controlled alongside other agent capabilities.

Dynamic personalization with Variables

Frontend Actions integrate seamlessly with CometChat's Variables system, enabling you to inject dynamic, user-specific data into action parameters. This means your actions can be personalized based on who's using them and the context of the conversation.

Variables come in two types:

Auth Variables (automatically provided):

@var-auth:sender.uid - unique identifier of the message sender
@var-auth:sender.name - display name of the message sender
@var-auth:sender.role - role of the message sender

Custom Variables (user-defined with three source types):
Constant - static values like API keys or company name

Message Metadata - extracts data from message.data.metadata (e.g., orderId, sessionType)

User Metadata - extracts data from sender's user metadata (e.g., subscription tier, department)

For example, when your agent opens a support form, you can pass @var-auth:sender.name to pre-fill the name field and @var-custom:subscriptionTier to automatically route them to the right support queue. When navigating to an order details page, inject @var-custom:orderId to deep-link directly to the relevant order.

Variables are managed in the Agent Builder's Variables section and can be referenced in both agent instructions and Frontend Action parameters using the @ syntax.

Per-agent enablement

Every Frontend Action can be toggled on or off for individual agents. Once enabled, agents can intelligently decide to use the action based on its description - no explicit instruction required. For more control, you can reference actions directly in agent instructions to provide nuanced guidance on when they should be triggered.

Real-time SDK integration

When an agent invokes a Frontend Action, your client application receives it as a tool call event through the SDK. Register action handlers with your UIKit component using the aiAssistantTools property, mapping trigger function identifiers to callback functions. UIKit automatically routes tool calls to the correct handler, passing along any parameters the agent provided.

Orphaned action detection

If a Frontend Action is deleted, renamed, or disabled after being referenced in agent instructions, the dashboard displays a warning indicator. This makes it easy to spot and fix broken references before they impact production experiences.

Interesting tech details

Under the hood, Frontend Actions leverage the same tool-calling infrastructure that powers API integrations, but instead of making external requests, they trigger client-side JavaScript callbacks. This design keeps your application logic where it belongs, in your codebase, while giving agents the intelligence to invoke it at the right moments.

The action invocation flow is event-driven. When an agent determines a Frontend Action should fire, it generates a tool call that propagates through the real-time SDK layer. Your registered handler receives the trigger function identifier and parameters, executes your custom logic, and the conversation continues seamlessly. There's no server round-trip required for these interactions, keeping response times fast and UX smooth.

Variables are resolved server-side before actions reach your client. Auth variables pull from the authenticated user context, Message Metadata variables extract values from message.data.metadata using path-based lookups, User Metadata variables query the sender's user object, and Constants return their configured static values. Your action handlers receive clean, ready-to-use data without additional resolution logic.

Frontend Actions gives you a structured, scalable way to connect agent intelligence with application behavior, so you can focus on building conversational experiences that truly help users get things done.

How to Implement In-App Chat Using a Chat SDK: Complete Guide + CometChat Examples

CometChat — Fri, 06 Mar 2026 07:08:52 +0000

Building real-time chat into your application used to mean weeks of backend development, WebSocket management, and infrastructure headaches. Today, chat SDKs have changed the game entirely. With the right SDK, you can have a fully functional chat system running in your app in a matter of hours, not weeks.

If you're a developer or product owner researching how to add chat functionality to your application, you're likely weighing your options: should you build from scratch or integrate an SDK? And if you choose an SDK, what does the implementation process actually look like?

This guide walks you through exactly how chat SDK integration works, from the general implementation flow to framework-specific details using CometChat as a reference. Whether you're building for web, mobile, or cross-platform, you'll understand the process end-to-end and know what to expect at each stage.

Understanding Chat SDK Integration: The General Process

Before diving into any specific platform or framework, it helps to understand what happens under the hood when you integrate a chat SDK. The process is remarkably similar across most modern chat SDKs, though the syntax and specific implementation details vary.

Here's the typical workflow:

i) Installing the SDK
You start by adding the SDK to your project as a dependency. This might be through npm, CocoaPods, Gradle, or pub.dev, depending on your platform. The SDK package contains all the pre-built modules you need for chat functionality.

ii) Initialising the SDK
Once installed, you initialize the SDK with credentials from your chat provider. Usually an App ID or API key. This establishes the connection between your application and the chat infrastructure. Initialization typically happens once when your app starts.

iii) Authenticating Users
Before users can send or receive messages, they need to be authenticated with the chat system. This usually involves logging them in with a unique user ID and an authentication token. The SDK handles the session management and keeps users connected.

iv) Setting Up Conversation and Messaging Modules
With authentication complete, you can access the SDK's messaging APIs. This is where you build out the UI components conversation lists, chat windows, message composers and connect them to the SDK's data layer.

v) Sending and Receiving Messages
The SDK provides methods to send text messages, media files, and custom data. Receiving messages works through callback listeners or event handlers that fire in real-time when new messages arrive.

vi) Listening to Real-Time Events
Modern chat isn't just about messages. You need to handle typing indicators, read receipts, user presence, delivery statuses, and more. SDKs expose event listeners that let you react to these activities as they happen.

vii) Handling Groups and Advanced Features
Most chat SDKs support group conversations, user roles, message threading, reactions, and other advanced features. The SDK provides APIs to create groups, manage members, and handle permissions.

viii) Error Handling and Infrastructure Considerations
Production chat systems need to handle network failures gracefully, implement retry logic, manage rate limits, and scale with user growth. Quality SDKs abstract away most of this complexity but give you hooks to customize behavior when needed.

This is the conceptual framework that applies whether you're using CometChat, Sendbird, Stream, or any other chat SDK. The specific code syntax changes, but the implementation pattern stays consistent.

Implementing In-App Chat with CometChat SDK: Step-by-Step

Integrating chat with CometChat follows the same overall pattern, but with a smoother developer experience and more flexibility across platforms. The steps below apply to every CometChat SDK: React Native, Flutter, iOS, Android, JavaScript, and Ionic.

1. Get Your Application Keys
Sign up for a CometChat account and create a new app from the dashboard to receive your unique App ID, Region, and Auth Key. These credentials securely connect your application to CometChat's infrastructure and authenticate your requests

2. Add the CometChat Dependency
Install the CometChat SDK into your project using your platform's package manager- npm for JavaScript and React Native, CocoaPods or SPM for iOS, Gradle for Android, or pub.dev for Flutter. This single dependency includes everything you need for real-time messaging, groups, media sharing, and more.

3. Initialize CometChat
Call the initialization method in your app's entry point with your App ID and Region to establish the connection to CometChat's servers. This one-time setup prepares the SDK for all subsequent chat operations throughout your application's lifecycle.

4. Register and Login Your User
Create user accounts either through the CometChat dashboard or programmatically via the SDK, then authenticate users by logging them in with their unique user ID and auth token. Once logged in, users can send messages, join groups, and receive real-time updates.

5. Integrate Our UI Kits
Drop in CometChat's pre-built UI components to get a complete chat interface with conversation lists, message threads, user profiles, and all interactive features working immediately. These production-ready components are fully customizable and handle all the complex state management and real-time synchronization for you.

6. Integrate Our Chat Widget
For web applications, embed CometChat's widget with just a few lines of code to add a fully functional chat interface to any webpage. The widget is perfect for customer support, community engagement, or adding chat to marketing sites without building custom UI.

The exact install commands, initialization syntax, and UI setup vary slightly based on the framework you're using. Below are framework-specific considerations and links to detailed documentation.

You can check out our documentation for more detailed step by step instructions.

While the integration flow stays the same, the installation steps and syntax vary slightly depending on the framework you’re using.

React Native SDK

React Native developers get the advantage of writing chat functionality once and deploying to both iOS and Android. Our React Native chat SDK integrates seamlessly with React Native's component lifecycle and supports all native features like push notifications and deep linking.

What differs: Installation uses npm or yarn, and initialization happens in your root component. You'll work with React hooks and state management to handle real-time updates.

Platform considerations: You'll need to configure native modules for both iOS and Android, handle platform-specific permissions for media access, and set up push notification services for each platform.

Flutter SDK

Flutter's cross-platform approach extends naturally to chat. CometChat's Flutter SDK lets you build once and deploy to iOS, Android, web, and desktop from a single codebase.

What differs: Installation uses pub.dev, and you'll work with Flutter's widget tree and state management patterns like Provider or Riverpod. The SDK provides Flutter-friendly APIs that feel natural to Flutter developers.

Platform considerations: Handle platform channels for native functionality, configure permissions in both iOS and Android manifests, and optimize for hot reload during development.

Android SDK

For native Android development, the CometChat Android SDK provides a Kotlin-first API with Java support. It integrates with Android's lifecycle architecture and Material Design components.

What differs: Installation uses Gradle, and initialization typically happens in your Application class. You'll work with Android's Activity and Fragment lifecycle, ViewModels, and LiveData patterns.

Platform considerations: Handle Android-specific permissions, background service restrictions, battery optimization, and push notifications through Firebase Cloud Messaging.

iOS SDK

The iOS SDK is built with Swift and supports SwiftUI and UIKit. It follows iOS design patterns and integrates with Apple's ecosystem features like CallKit and PushKit.

What differs: Installation uses CocoaPods or Swift Package Manager, and initialization happens in your AppDelegate or App struct. You'll work with delegates, closures, and Combine publishers for real-time updates.

Platform considerations: Handle iOS permissions, background modes, push notification certificates, and App Store submission requirements.

JavaScript SDK

For web applications, the JavaScript SDK works with vanilla JavaScript or any modern framework like React, Vue, or Angular. It's lightweight and optimized for browser environments.

What differs: Installation uses npm or a CDN link, and initialization happens on page load or app mount. You'll work with Promises, async/await, and browser APIs for real-time communication.

Platform considerations: Handle browser compatibility, WebSocket connections, local storage for persistence, and service workers for push notifications on the web.

Ionic SDK

Ionic developers get a hybrid approach that combines web technologies with native capabilities. The CometChat Ionic SDK leverages Capacitor or Cordova plugins for device access.

What differs: Installation works through npm with additional native configuration. You'll integrate with Ionic's component library and use Angular, React, or Vue depending on your Ionic setup.

Platform considerations: Configure native plugins for both platforms, handle Cordova/Capacitor bridge communication, and test across web, iOS, and Android builds.

On-Premise Deployment with CometChat: Complete Control Over Your Messaging Infrastructure

CometChat — Wed, 18 Feb 2026 08:12:03 +0000

Instead of relying on our managed cloud service, you can now run the entire CometChat platform on your own servers using CometChat's on-prem deployment. This enables you to deploy CometChat within your own infrastructure, whether on private cloud, data centers, or air-gapped environments, with full data sovereignty and enterprise-grade performance. This makes it possible to meet strict compliance requirements, control data residency, and achieve predictable costs at scale while maintaining the same feature-rich messaging experience your users expect.

Why does this matter to me, as a developer?

Real-time messaging infrastructure is critical, but it's not one-size-fits-all. Many organizations face regulatory requirements, data sovereignty mandates, or security policies that make cloud-hosted solutions challenging or impossible to adopt.

With CometChat On-Premise, you can:

Meet compliance requirements by keeping all user data within your controlled infrastructure, essential for GDPR, HIPAA, SOC 2, and industry-specific regulations.
Eliminate per-user pricing unpredictability with fixed infrastructure costs, making budgeting and scaling more transparent as your application grows.
Deploy in air-gapped or restricted environments where external cloud services aren't permitted, such as government, defense, or highly regulated industries.
Achieve consistent sub-100ms latency with dedicated resources and optimized data locality, rather than competing for shared cloud resources.
Integrate with existing security infrastructure including private networks, custom authentication systems, and internal monitoring tools.
Integrate with existing security infrastructure including private networks, custom authentication systems, and internal monitoring tools.

This gives you the flexibility to design communication experiences that align with your organization's security, compliance, and operational requirements.

Key features and capabilities

Multiple deployment options

Choose between Docker Swarm (recommended for 10k-200k monthly active users) or Kubernetes (for enterprise and multi-region deployments). Both options provide production-grade reliability with different operational complexity profiles.

Complete feature parity

All CometChat features work identically in on-premise deployments: 1:1 and group messaging, typing indicators, read receipts, push notifications, webhooks, content moderation, and our complete REST API suite.

Polyglot persistence architecture

The platform uses purpose-built data stores optimized for specific workloads: TiDB for distributed SQL with ACID guarantees, MongoDB for flexible document storage, Redis for sub-millisecond caching, and Kafka for guaranteed event delivery.

Enterprise monitoring and observability

Built-in Prometheus, Grafana, and Loki stack provides real-time operational dashboards, SLA monitoring, and comprehensive audit trails, giving you complete visibility into system behavior.

Interesting tech details

This deployment architecture builds on cloud-native principles and battle-tested open-source technologies, designed to handle enterprise workloads from day one.

The platform employs a microservices architecture where:

Stateless services enable linear scaling by adding compute resources without data migration or architectural changes.
Apache Kafka serves as the central event backbone, providing guaranteed message ordering, fault-tolerant persistence, and effectively-once delivery semantics.
WebSocket gateway maintains persistent connections with automatic reconnection handling and session recovery for uninterrupted real-time experiences.
Encrypted overlay networking isolates backend services with service-to-service communication secured by default within the Docker Swarm cluster.

This approach ensures your messaging infrastructure remains reliable, predictable, and scalable as your application grows from thousands to hundreds of thousands of monthly active users.

2025 at CometChat: A year of smarter, cleaner and more clearer chat experiences

CometChat — Mon, 09 Feb 2026 12:05:19 +0000

If there was one theme that defined chat in 2025, it was clarity at scale.

As apps grew more global, conversations got longer, faster, and more complex. developers weren’t just asking for “chat that works”, they wanted something that stays usable as users, messages, and markets grow.

This year, CometChat shipped some of its most practical chat upgrades yet. Not flashy for the sake of it but thoughtfully designed features that make everyday conversations easier to follow, easier to search, and easier to localize.

Here’s a quick recap of the standout chat features from 2025 and why they mattered.

Quoted Replies: Context Without Chaos

Modern conversations don’t move in straight lines. Group chats branch. Messages overlap. Replies arrive late. Context gets lost fast.

Quoted replies solved that.

With swipe-to-reply (on mobile) and reply actions on the web, users can now respond directly to any message by bringing the original text along with it. The result? Conversations that stay readable even when they get busy.

Why this matters

Multi-threaded chats stayed organized without forcing full threading
Users could instantly understand what a reply was referring to
One tap took them back to the original message no endless scrolling

For developers, this came ready out of the box across CometChat UI Kits. No custom state handling. No UI hacks. Just cleaner conversations by default.

Message Search: Finding the Needle in the Chat Haystack

As chat histories grew into thousands of messages, scrolling stopped being an option.

In 2025, CometChat extended Conversation Search and Advanced Message Search bringing powerful discovery tools to Android, iOS, and Flutter.

Users can now:

Search conversations by user or group name
Find messages by file name, media type, links, or mentions
Filter messages by time range or sender
Jump directly to the exact result, instantly

Why this matters:

Search isn’t a “nice-to-have” anymore. It’s a usability requirement especially for enterprise apps, communities, and long-running conversations.

This update made mobile chat feel just as capable as web, without loading massive message histories or hurting performance.

Localization: Production-ready, not an afterthought

Going global used to mean rebuilding your chat UI language by language.

Not anymore.

In 2025, CometChat’s React Native UI Kit introduced production-ready localization through CometChatI18nProvider. It ships with 19 languages out of the box, automatic locale detection, and full support for custom translations powered by react-native-localize.

What developers got

Centralized language management at the provider level
Automatic detection based on device settings
Full override support for custom strings or new languages
Graceful fallback handling when translations are missing
A hook-based API (useCometChatTranslation) for custom components

Why it matters:

Localization directly impacts adoption and retention. This update made it possible to ship truly global chat experiences without rebuilding UI components or maintaining brittle translation logic.

The Bigger Picture: Chat that scales with humans

Individually, these features solve specific problems. Together, they reflect a bigger shift in how CometChat approached chat in 2025:

Clarity over complexity (quoted replies)
Speed over friction (advanced search)
Global readiness by default (localization)

None of these features shout for attention. But users feel them every day, in smoother conversations, faster discovery, and experiences that feel native no matter where they’re used.

And that’s what good chat should do.

Looking Ahead

2025 was about making chat work better at scale. Not just technically but socially, globally, and humanly.

If this year proved anything, it’s that the best chat features aren’t the loudest ones. They’re the ones users stop noticing because everything just feels easier. We’re very excited to see all the new features and solutions going to unfold in 2026.

Here’s to building conversations that scale.

Cheers!
