Self-hosted voice chat server. A lightweight, single-binary alternative to Discord focused on voice communication.
- WebRTC SFU — Low-latency voice powered by Pion WebRTC, using a Selective Forwarding Unit architecture for efficient multi-party audio
- Voice Activity Detection — Real-time VAD with configurable sensitivity threshold and visual audio level meter
- Push-to-Talk — Optional PTT mode activated with spacebar
- Screen Sharing — Share your screen with live preview thumbnails for other users
- Channels — Create and manage voice channels with real-time presence and user counts
- Authentication — Session-based auth with bcrypt password hashing, HTTP-only cookies, and CSRF protection
- Single Binary — No external dependencies. SQLite database, embedded templates, one process to run
- Modern UI — Dark-themed interface built with HTMX and Tailwind CSS, no frontend build step
- Go 1.21+
- C compiler (required for SQLite via cgo)
