Gryt is a self-hosted platform for real-time voice, video and text communication. It combines a desktop and web client with its own signalling server and Selective Forwarding Unit, giving users an alternative to centrally hosted communication services.
Voice, camera video and screen sharing use WebRTC. The media server is built with Go and Pion and forwards streams between participants without transcoding. The client adds features such as push-to-talk, noise suppression, voice activity detection and screen sharing with audio. Text conversations support Markdown, mentions, uploads and persistent message history.
Servers can be deployed with Docker Compose, while larger installations can use Helm. Accounts are optional: a server can admit guests without requiring them to create an account with the Gryt service. The desktop application is available for Linux as AppImage and DEB packages, with Snap and Arch Linux options also available. There is also a browser client, and the desktop client can host a server itself.
Gryt remains under active development, so administrators should expect changes as the platform matures.
This is free and open source software.
