We’re migrating to V3 — a fully rebuilt backend in Rust, powered by str0m — a sans-IO WebRTC implementation for maximum performance, flexibility, and control over media handling.
This release brings advanced live streaming, adaptive media delivery, and bandwidth-efficient calls, engineered for low deployment costs and exceptional quality.
Waterbus is a modern open-source video conferencing platform built with Flutter, Rust, and WebRTC (via str0m).
It powers virtual meetings, webinars, live streaming, and real-time collaboration — delivering smooth audio/video, screen sharing, interactive chat, and more.
Whether you run it for your team, organization, or integrate it into your own product, Waterbus is designed for:
- 🟢 Cross-platform — Web, Desktop, and Mobile.
- ⚡ Ultra-low latency — Rust-powered SFU built on str0m’s sans-IO design.
- 🌍 Scalable architecture — From 1-on-1 calls to large events.
- 💡 Developer-friendly — APIs, SDKs, and modular design.
