Caution
Early Development Stage — This project is experimental and under active development. Expect breaking changes.
Most communication platforms today are owned by corporations that monetize your conversations, lock you into their ecosystem, and give you zero control over where your data lives. Gryt exists to change that.
- Self-hostable — Run your own server. Your data stays on your hardware.
- Open source — Every line is auditable. No telemetry, no tracking, no surprises.
- Full-featured — Crystal-clear voice chat, persistent text messaging, file sharing — all in one platform.
- Modern stack — Built with TypeScript, React, Go, and WebRTC for real-time performance.
