Open Bsp Api

OpenBSP is an open source WhatsApp Business Platform that connects an application directly to Meta's WhatsApp Cloud API, with no third party business solution provider in between. It positions itself as an open source alternative to Twilio for WhatsApp, and it also offers a WhatsApp Web style interface for WhatsApp and Instagram messages. A backend repository holds the API and a separate UI repository provides the web interface. The backend is written in TypeScript on Deno Edge Functions and Postgres, and it is designed to run on Supabase. The vendor says a self hosted deployment can be live in under fifteen minutes by forking the repository, setting GitHub secrets and running a release action. A hosted version runs the same code. The system is multi tenant with row level security and role based access, so it can serve a single business or be offered to clients. For AI use, the platform is decoupled from any particular model: agents can be plugged in through Chat Completions, the A2A protocol or MCP, and a built in MCP server serves agentic clients. Sign in on the web app is by email, Google or GitHub. The code is released under the Unlicense. The site publishes no platform fee. It compares monthly costs with Twilio, saying Meta conversation fees of roughly $30 for 10,000 messages apply either way, with Supabase hosting free at small volumes and $25 per month on its Pro tier at higher traffic.
