A reverse-engineered description and Node.js re-implementation of the WhatsApp Web API, communicating over WebSockets with the same encryption and binary protobuf protocol. It serves as documentation and a foundation for building custom unofficial WhatsApp clients.
Use cases
- send whatsapp messages programmatically without official api
- understand how whatsapp web protocol works
- build a custom whatsapp client in node.js
- intercept and analyze whatsapp web websocket traffic
- automate whatsapp messaging for research
- implement whatsapp web encryption curve25519 protobuf
When to choose
- you need deep protocol-level understanding of WhatsApp Web internals
- you want a Node.js starting point for an unofficial WhatsApp client
- you are researching WhatsApp's WebSocket encryption and protobuf format
When to avoid
- you need a reliable production messaging integration - the unofficial API can break anytime and risks account bans
- you want official support or stability guarantees
- your project requires maintained, up-to-date WhatsApp automation - consider official WhatsApp Business API instead
