Looking for a feature-rich, secure, easy-to-integrate, customizable in-app chat solution that you don't have to build from scratch? We've compiled a list of the top seven CaaS providers on the market today, highlighting the benefits, features, and limitations so that you can make the right decision for your product.
In-app chat's ability to build community, create brand loyalty, improve user retention, and increase engagement is responsible for its popularity. If your brand could use a boost in any of these areas, consider adding chat to your product roadmap. But, since building a chat app from scratch is often more trouble than it's worth, here are seven of the top chat as a service (CaaS) providers that will help you easily integrate chat into your product.
1. Stream Chat
Stream is one of the top chat services on the market. And some of the world's most well-known companies already use it, including Vimeo, The Boys and Girls Club of America, and Adobe.
It's an incredibly versatile option you can use to create a robust chat, even without prior experience building a messaging infrastructure. In addition to its chat API, Stream offers more than a dozen SDKs, including a React SDK and those specifically designed for iOS and Android app environments. The variety of options available ensures that you'll find a package that contains everything you need to build and customize your own chat right out of the box.
Benefits
Easy to build and implement. Get chat up and running quickly with the easy-to-integrate API or access Stream's library of pre-written code.
Customize the chat experience. Enhance the out-of-the-box solution by editing the code yourself or using third-party platforms like Giphy and Imgur.
Try before you buy. Sign up for a free trial to test drive Stream's API or SDKs before you spend any money.
Make more reliable connections. Stream boasts nearly 100% uptime and 5x fewer issues from poor Wi-Fi connections.
Ensure security compliance. Stream's chat meets some of the strictest industry regulations (including HIPAA, SOC-2, and GDPR) — a great option for products in tightly regulated industries like telehealth.
Top Features

Unlimited number of chat users makes in-app conversations more collaborative.
AI Moderation include the ability to mute or ban accounts, hide or flag messages, and set channel permissions.

Limitations
- Video Looking to take your app engagement to the next level? Incorporating video is a great way to boost the benefits of native messaging, but Stream's video service will not be available for another few months.
2. Agora
Agora specializes in SDKs for voice calling and video conferencing — but it also offers a chat service for private and group chat capabilities. It's a particularly good option for web conferencing apps that already rely on Agora's other APIs and SDKs because they're all compatible. And that means they'll integrate with one another seamlessly.
Benefits
Moderate content automatically. Agora automatically moderates sensitive content like profanity to create a safe environment for all users.
Get up and running quickly. Getting Agora's chat up and running only requires a few lines of code. To make things even easier, Agora provides pre-written code that you can copy and paste.
Keep user data secure. Data privacy compliance is easy with the SDK's file encryption and user controls for their chat histories.
Use your favorite third-party integrations. Customize the chat's functionality by integrating with third-party platforms like Giphy.
Top Features
Offline messaging allows users to communicate asynchronously.
Auto-translation enables users to communicate in their preferred language.
Limitations
- Functionality. Agora's chat SDK only supports the most basic messaging functionality — read receipts, typing notifications, push notifications, etc.
3. Twilio
Twilio is a leader in customer engagement with an emphasis on its data collection capabilities in all of its products. Twilio offers a wide array of APIs and SDKs, including Twilio MessagingX, which includes two API offerings that help developers integrate multi-channel chat services into their products:
Programmable Messaging API: Developers can use this API to send transactional messages through SMS, MMS, or WhatsApp. This API is great for ecommerce websites, which can use transactional messaging for things like shipping and delivery updates.
Conversations API: With Twilio's SDK, you can integrate conversational messaging into apps. This API can handle robust chat needs, like providing real-time support through live chat.
Benefits
Connect with users through multiple channels. The chat service is compatible with a variety of already-popular messaging platforms, including standard text messaging, Facebook Messenger, and Google Business.
Expand your development knowledge and skill set. Twilio supports customers beyond basic implementation resources by offering both live and on-demand virtual training sessions on a variety of topics that support long-term development efforts.
Improve future communication with data-backed insights. First and foremost, Twilio is a consumer engagement and data collection tool. And that means you gain insights about customers by integrating its other APIs.
Top Features

Message notifications
User authentication
Real-time analytics
Conversations API
Multi-channel messaging
Delivery and read receipts
SMS and MMS messaging
Limitations
- Pricing. Twilio's pricing varies depending on factors like the number of users and the number of sent messages. This flexibility in pricing can make it difficult to estimate costs and create realistic budgets, especially for apps with fast-growing user bases.
4. PubNub
PubNub specializes in tools that help developers create engaging virtual experiences that create a community at a global scale.
PubNub is a great option for apps with large-scale messaging needs because the network relies on 15 internationally distributed data centers. This allows fast communication between users around the globe. Data center distribution also minimizes the risk of a crash since if one goes down, the service can rely on one of the others to keep operating.
Benefits
Guarantee compliance with important security and privacy standards. SDKs support compliance with HIPAA and SOC2 regulations — PubNub even undergoes third-party audits to help ensure data security for its users.
Build a unique chat with ease. Components make it easy to add a chat service because they give you a head start by creating the building blocks --- all you have to do is assemble them according to the provided directions.
Get assistance if you run into a hurdle. 24/7 access to support makes PubNub a good option for teams with limited development experience or limited time to troubleshoot errors.
Top Features
File sharing allows users to send photos, videos, and documents.
Moderation dashboard makes it easy to identify and hide inappropriate messages, respond to user-flagged messages, and mute individual users.
External storage automatically saves sent messages to a preselected, personal database.
Limitations
- Functionality. Popular functionalities require third-party integration — out of the box, Pubnub's chat service doesn't include the ability to send gifs, translate text, or trigger push notifications.
5. Comet Chat
CometChat offers APIs, SDKs, UI kits, and widgets that help developers integrate private and group chat into their own products with ease. Because it offers a combination of options, developers have a few options for how they integrate chat into their app or website:
Drag-and-drop chat widgets to integrate pre-built chat functionality in just a few minutes.
Customize and integrate a pre-built chat functionality with APIs on their own.
Speed up time to launch with bottom-up development by using a combination of SDKs with APIs.

Customization. CometChat limits the edits developers can make to the API and SDK code on their own, which means most customizations rely on extensions and third-party integrations.
Pricing. Advanced features like in-chat polling, message translation, and virus scanning are limited to the Pro Plan.
6. TalkJS
TalkJS is a dedicated chat API service provider that allows developers to integrate chat into any kind of app and employ it for a wide variety of use cases. This includes everything from basic one-on-one chats to real-time text messaging between businesses and customers. And as a company founded and run largely by developers, TalkJS regularly updates its services to remain competitive.
Benefits

Customization. Because TalkJS only offers an API (and no SDK), the only customization options are the built-in themes provided by TalkJS.
Pricing. Each price plan places a limit on the number of users, and the most affordable plans offer limited access to advanced features.
7. Quickblox
Quickblox supports developers that are building real-time chat. It also offers resources to build video calling and web conferencing features, which developers can use to support chat and create a more engaging and interactive experience for end users. Because Quickblox's primary goal is to help developers build apps that establish remote connections, some of its most common use cases include telehealth, eLearning, and remote work.
