Faxbot

The first and only open‑source, self‑hostable fax platform with a GUI‑first Admin Console, multi‑backend adapters (cloud + self‑hosted), and AI assistant integration.

GUI‑first: Admin Console

• One place to configure backends, keys, inbound, storage, and run diagnostics.
• Open http://localhost:8080 and use the Admin Console (served by the API).
• Traits‑first UI: screens render only what your active provider supports.

Why Faxbot

• One API, many backends: Phaxio, Documo, Sinch, SignalWire, and more (cloud), or self‑hosted FreeSWTICH, SIP/Asterisk, or anything else you can dream up.
• Ability to mix and match outbound and inbound providers, total freedom, fit to your infrastructure.
• HIPAA‑aligned controls: HMAC webhook verification, short‑TTL tokens, compliant logging.
• AI integration: official MCP servers (Node & Python) for stdio/HTTP/SSE with Webhook support.
• Identical SDKs: Node.js and Python with the same surface.

Quick start (Docker Compose)

1) Copy .env (see .env.example). Pick a backend:

• Phaxio (recommended): set FAX_BACKEND=phaxio and PHAXIO_API_KEY/PHAXIO_API_SECRET.
• Sinch: set FAX_BACKEND=sinch, SINCH_PROJECT_ID/SINCH_API_KEY/SINCH_API_SECRET.

> Or one of 20 others that we have pre-made manifests for you to quickly load.

• SIP/Asterisk: set FAX_BACKEND=sip and AMI vars (see docs).

2) Start the API (and Admin Console):

docker compose up -d --build api

3) Open the Admin Console: http://localhost:8080

Health checks:

• API: curl http://localhost:8080/health
• Ready: curl -i http://localhost:8080/health/ready

Optional MCP servers:

docker compose --profile mcp up -d --build faxbot-mcp
docker compose --profile mcp up -d --build faxbot-mcp-sse

iOS App (TestFlight)

The iOS companion lets you send faxes and check status from your phone. Email david@faxbot.net for an invite.

SDKs

• Python: pip install faxbot
• Node.js: npm install faxbot

→ [SDK Usage](docs/SDKS.md)

Architecture highlights

• Traits‑first capabilities: /admin/providers and /admin/config expose active providers + traits; UI and API gate features by traits.
• Canonical event & error model: normalized inbound/outbound events, status mapping, and standard error codes.
• Provider adapters: clean boundaries for verifywebhook/parseinbound/send/status/cancel.

Docs:

• [Canonical Events](docs/api/canonical_events.md)
• [MCP Integration](docs/MCP_INTEGRATION.md)
• [API Reference](docs/API_REFERENCE.md)

Security

• Use X-API-Key (multi‑key) for auth.
• Enforce HTTPS and HMAC signature verification for cloud webhooks.
• No PHI in logs; only IDs/metadata are surfaced.
