Finishing Chatmandu: Building a Unified Communication and Automation Platform

This is a submission for the GitHub Finish-Up-A-Thon Challenge.

What I Built

I built Chatmandu, a business communication and automation platform that combines WhatsApp Business API, Facebook page management, AI-assisted messaging, and developer-friendly automation tools into a single system.

The core idea behind Chatmandu is to remove the fragmentation that businesses face when managing customer communication and online presence. Instead of using separate tools for messaging, social media posting, automation, and team coordination, Chatmandu brings everything into one unified platform.

At its core, Chatmandu focuses on two major workflows:

First, WhatsApp Business communication, including official API access, bulk messaging, conversation handling, and AI-assisted replies.

Second, Facebook page automation, where businesses can create content using AI prompts, schedule posts, and manage publishing workflows directly from the platform.

Users can write prompts that generate content automatically, refine it, and schedule it for publishing across their Facebook pages. This allows businesses to maintain consistent social media presence without manually creating each post.

Beyond that, Chatmandu supports:

Official WhatsApp Business API integration
Bulk WhatsApp messaging campaigns
AI-assisted conversation handling
Facebook page post creation and scheduling
Prompt-based content generation for social media posts
Automated publishing workflows
Team-based role and permission management
Assignment of WhatsApp numbers or Facebook pages to specific users or teams
Developer APIs for building custom automation on top of the platform
Centralized dashboard for managing all communication channels

The system is designed to serve both non-technical users who just want to manage communication easily, and developers who want to extend automation into their own products or workflows.

The backend is built using NestJS, and the frontend is built with Next.js.

The platform currently includes:

WhatsApp Business API onboarding and messaging system
Bulk messaging for campaigns
AI-assisted conversation management
Facebook page integration
Prompt-based content generation for posts
Scheduled and automated Facebook publishing
Role-based access control for teams
Multi-account management across WhatsApp and Facebook pages
API access for automation and integrations
Unified communication dashboard

The Comeback Story

Chatmandu started as a small idea focused on messaging automation, but gradually evolved into a broader business communication and content automation platform.

As the scope expanded, so did the complexity. Managing WhatsApp integration, Facebook APIs, scheduling systems, AI workflows, authentication, and role-based permissions all within one system introduced multiple technical challenges.

At different stages, the project was left in an unfinished state:

Unstable messaging and social media integrations
Incomplete onboarding flows
Gaps in dashboard and UI design
Complex role and permission handling
API inconsistencies
Infrastructure and deployment challenges

The project stayed unfinished for a long time because it was trying to solve multiple real-world problems at once.

The Finish-Up-A-Thon became the motivation to stop expanding the idea and focus on completing a stable, usable product.

During this period, the focus shifted toward:

Stabilizing WhatsApp Business API workflows
Improving Facebook page integration and post scheduling reliability
Building and refining prompt-based content generation for posts
Cleaning up backend architecture in NestJS
Improving frontend experience in Next.js
Strengthening role-based access control
Making automation workflows reliable and predictable
Preparing the platform for real usage rather than experimentation

The most important shift was moving from building features to finishing a product that actually works end to end.

My Experience with GitHub Copilot

GitHub Copilot played a significant role throughout development and cleanup.

Given the size of the system, which includes integrations, APIs, automation logic, and frontend-backend coordination, Copilot helped reduce repetitive work and speed up implementation.

I used it for:

NestJS backend services and modules
API development and webhook handling
Facebook and WhatsApp integration logic
Database schema design and queries
Refactoring large sections of backend code
Authentication and authorization flows
Next.js UI components
Debugging and cleanup across the codebase

It was especially useful during refactoring and stabilization phases, where consistency and speed mattered more than writing everything from scratch.

Why I Built This

Businesses today rely on multiple disconnected tools to manage communication and online presence. WhatsApp messaging, Facebook posting, customer support, and automation are often handled separately, creating inefficiency and missed opportunities.

I wanted to build a system that brings these workflows together into a single platform, while still remaining flexible enough for developers and teams with different needs.

Chatmandu is the result of trying to solve that fragmentation problem in a practical way.

This project also represents persistence. It went through multiple unfinished stages, and this time the focus was on completing it into a usable, production-ready system.

The goal was not to keep adding more ideas, but to finally ship something that works end to end.

I built ChatMandu - a WhatsApp-focused web app from Nepal

Hi everyone

I’m a software developer from Nepal with 2+ years of experience in Laravel and Node.js.

Recently, I built a web app called ChatMandu.

ChatMandu is a lightweight web platform built around improving how users interact with chat and communication workflows. The goal was to keep it simple, fast, and practical - not overloaded with unnecessary features.

I built this project while experimenting with real-world product development, focusing on:

clean UX
performance
solving communication-related use cases in a simple way

This is still an early version, and I’m actively improving it based on real user feedback.

I need feedback from you

If you try ChatMandu, I’d really appreciate honest feedback on:

What feels confusing
What feels useful
What should be improved or removed
Would you actually use this

Try it here

Thanks for checking it out

Any feedback, even critical, is very welcome.
