Effortless screensharing powered by WebRTC.

Prerequisites

TURN Server Setup

To enable connections through restrictive NATs, you need a TURN server. We use Metered's Open Relay which provides 50GB/month free.

1. Sign up for a free account at https://dashboard.metered.ca/signup

2. Create a new app (you'll get an app name like yourapp.metered.live)

3. Copy your API key from the dashboard

4. Fill in your credentials in .env:

METERED_APP_NAME=yourapp
METERED_API_KEY=your_api_key_here
REDIS_URL=redis://localhost:6379
