OpenBSP is an open-source, self-hostable WhatsApp Business Platform. It connects directly to Meta's Cloud API. You can run it for yourself or offer WhatsApp services to clients as a Meta Business Partner. Runs on Supabase and deploys in under 15 minutes via GitHub Actions.
The platform focuses on the communication and context layer. AI agents are first-class but the architecture is deliberately decoupled — you're encouraged to build and deploy agents externally using whatever framework fits (OpenAI SDK, Google ADK, LangGraph, etc.) and connect them via Chat Completions or A2A.
There's also a built-in MCP server, so you can access your WhatsApp conversations from any agent platform.

Running in production at my employer Mirlo.com. Happy to answer questions about the WhatsApp Business API, the architecture, or anything else.
