Add live translationWhy this kit exists
- WebRTC is a month of yak-shaving: SDP, ICE, codec payload types, reconnection, TURN.
- Open-source samples stop at “hello world” — no reconnect, no diagnostics, nothing you can ship.
- Managed platforms cost $0.10–1.00 per 1000 minutes and hand you a black box when it breaks.
What you get
- Signaling server + SFU (Go, Pion) — one binary, no external services
- Browser publisher (camera / screen share) and viewer with autoplay handling
- Auto-reconnect: ICE restart first, full rejoin as fallback — with jittered backoff
- Freeze detection via
requestVideoFrameCallbackplus a live stats panel - Plain-English failure hints (no TURN? bandwidth too low? waiting for a keyframe?)
- docker-compose deploy behind Caddy and HTTPS, plus a coturn config and
-turnflags pitfalls.md: the traps we hit building this, symptom → cause → fix
Building or repairing your own stack first? Use the MIT-licensed recovery library and its interactive demo. No account required.
Who it is for
Remote inspection and remote assistance tools, teleoperation / robot dashboards, live monitoring walls, IoT camera apps, field-service apps with a “see what I see” button, and internal demos. If your requirement is “under a second, in a browser, self-hosted” — this is the 20% you need.
