OpenBunny connects to WhatsApp Web using the Baileys library. This uses your personal WhatsApp account — no WhatsApp Business API required.
Setup
Select WhatsApp when prompted. A QR code will be displayed in your terminal.
Open WhatsApp on your phone, go to Linked Devices, and scan the QR code.
Once authenticated, the service begins receiving messages from your WhatsApp chats.
How it works
The service uses the Baileys library to connect to WhatsApp Web via the multi-device protocol. Session credentials are stored locally so you don’t need to re-scan on restart.
WhatsApp Web connections can be disconnected if you link too many devices or if WhatsApp detects unusual activity. If disconnected, re-run the setup wizard to re-authenticate.
Notes
- Uses your personal WhatsApp account, not WhatsApp Business API
- Group chats and individual chats are both supported
- Media messages (images, documents) are noted but not processed by the LLM
- Session persists across restarts
