OpenBSP
Open-source WhatsApp Business Platform — connect directly to Meta's Cloud API.
What it is
OpenBSP connects your stack directly to Meta's WhatsApp Cloud API. No third-party BSP between you and Meta. Self-host on Supabase or run the hosted version — same code.
Self-hostable
Fork, set GitHub secrets, run the Release action. Live in under 15 minutes.
Multi-tenant
Row-level security, role-based access. Run it for yourself or offer it to clients.
AI-agent ready
Decoupled. Plug in any LLM framework via Chat Completions, A2A, or MCP. Built-in MCP server for agentic clients.
Open source
TypeScript, Deno Edge Functions, Postgres. Unlicense (public domain) — use it however you want.
Cost compared to Twilio
10,000 messages/month, ~1,000 of them business-initiated (templates that open new conversations — the only type Meta charges for):
| Twilio | OpenBSP | |
|---|---|---|
| Platform fee | $0 | $0 |
| Per-message markup | ~$50 | $0 |
| Meta conversation fees | ~$30 | ~$30 |
| Hosting | $0 | $0 |
| Total | ~$80/mo | ~$30/mo |
Supabase's free tier covers SMB volumes. Pro ($25/mo) kicks in at higher traffic. You can also self-host Supabase itself, but that's another story.
