An open-source alternative Twitch desktop client, built with Tauri 2, React, TypeScript, and Rust.
Secousse is French for "twitch" (as in a sudden movement).
- Live Stream Playback - HLS video streaming with quality selection
- Multi-stream Grid - Watch up to 4 streams at once in a split-screen layout; audio routes to the focused tile
- Pop-out Windows - Detach any stream into an independent window with optional always-on-top
- Chat - Real-time chat with emote support (Twitch, 7TV, BTTV, FFZ)
- Authentication - OAuth login to access your followed channels and send chat messages
- Follow/Unfollow - Manage your followed channels directly from the app
- Browse - Discover top live streams
- Search - Find channels quickly
- Frontend: React 19, TypeScript, Tailwind CSS v4, Vite
- Backend: Rust with Tauri 2
- Video: HLS.js with custom Tauri loader for CORS bypass
- Chat: IRC WebSocket connection
- APIs: Twitch GQL (public data) + Helix API (authenticated operations)
