Realtime video & voice, in minutes.

Relay is an open-source, self-hostable LiveKit gateway. Mint access tokens from one simple API and let your users talk — using standard LiveKit clients, no lock-in.

Add video in 5 minutes

Mint a token from your server with a single request.

bash

curl -X POST https://api.relay.welbuiltai.tech/v1/tokens \
  -H "Authorization: Bearer sk_live_your_key" \
  -H "Content-Type: application/json" \
  -d '{"room":"my-room","identity":"user-123"}'
# → { "token": "...", "url": "wss://...", "room": "..." }

Pass token + url to any LiveKit client SDK to join.

Everything you need to ship realtime

A thin, predictable gateway in front of LiveKit.

Per-project isolation

Tokens are scoped to your project and rooms are auto-namespaced, so projects never collide.

Usage metering

Track participant-minutes in real time and see your savings versus Twilio at a glance.

No client lock-in

Join with the standard LiveKit client SDKs. Relay only mints tokens — the media path is pure LiveKit.
