## What it is
CodeChat is a self-hosted REST API service built on the Baileys library that exposes WhatsApp functionality (instances, messaging, chats, groups, media, calls, webhooks) over HTTP. It lets developers integrate WhatsApp into any system without writing Node.js code, managing multiple isolated WhatsApp sessions via JWT-authenticated instances.

## Use cases
- send and receive whatsapp messages from my app via rest api
- self-host a whatsapp api server with multi-instance support
- build a whatsapp chatbot without writing javascript
- integrate whatsapp notifications into my crm via webhooks
- manage multiple whatsapp numbers with one api
- send bulk whatsapp messages with a queue
- connect whatsapp using qr code or pairing code programmatically

## When to choose
- you need programmatic WhatsApp access from any language via REST
- you want to self-host and control your own WhatsApp gateway
- you need multi-tenant or multi-number instance management
- you want webhook and websocket event delivery for incoming messages

## When to avoid
- you need an officially supported WhatsApp Business API with guaranteed compliance
- you cannot accept the risk of unofficial automation being blocked by WhatsApp
- you need a managed SaaS rather than running Docker, PostgreSQL, and Node.js yourself
