WhiskeySockets/Baileys
Baileys exposes WhatsApp Web through a WebSocket-based TypeScript API, but v7 introduces breaking changes and remains unofficial, making migration and platform risk the main concerns.
Baileys is an **MIT-licensed** TypeScript library for interacting with WhatsApp Web over WebSockets. **Version 7.0.0** introduced multiple breaking changes, with a separate migration guide available.
Builders should review that guide before upgrading and keep the WhatsApp integration isolated behind their own adapter. The project’s new documentation is still incomplete, so the older README may remain useful.

Builders should review that guide before upgrading and keep the WhatsApp integration isolated behind their own adapter. The project’s new documentation is still incomplete, so the older README may remain useful. This is an **unofficial WhatsApp integration** with no affiliation or endorsement from WhatsApp. The maintainers discourage spam and automated bulk messaging, and usage remains subject to platform and terms-of-service risk.
This adds a low-level route to WhatsApp alongside broader multi-channel agent SDKs, but it narrows the option to teams willing to own an adapter, migration work, incomplete documentation, and platform-policy exposure. The unofficial status and v7 breaking changes make isolation more than an architectural preference: it limits the impact of upstream churn or a later replacement.
