Introduction

Gryt is a WebRTC-based voice chat platform built with TypeScript, React, Go, and Keycloak. It provides low-latency voice communication with noise suppression, echo cancellation, and a modern UI.

Components

Component	Tech	Role
Client	React + TypeScript (Electron)	UI, audio processing, WebRTC
Server	Node.js + TypeScript	Signaling, rooms, user state
SFU	Go + Pion WebRTC	Media forwarding
Auth	Keycloak (hosted)	OIDC authentication

How it works

Users authenticate via Keycloak (OIDC + PKCE)
The client connects to a signaling server over WebSocket
When joining a voice channel, the server coordinates a WebRTC session through the SFU
The SFU selectively forwards audio tracks between participants
