The Lightweight Stack
for Real-Time Media
Rust WebRTC SFU core. HTTP signaling. Modular services. If your client speaks WebRTC, it can talk to PulseBeam.
PulseBeamAn Opinionated Real-Time Stack
Designed from the ground up to be simple, reliable, and easy to extend.
Rust SFU Core
Fast, memory-safe, and concurrent without garbage collector pauses.
HTTP Signaling
WHIP/WHEP-compatible, extended for multi-party use cases. No WebSockets required.
SDK Optional
Any client that speaks WebRTC can connect directly. Thin SDKs will exist for convenience.
Modular by Design
Features like recording, analytics, or AI live outside the core as separate processes.
Compatibility
H.264 Baseline up to L4.1, Opus audio, and wide hardware acceleration support.
Open Source
AGPL-3.0 for server, Apache-2.0 for client libraries. Internal use is welcome.
Quickstart
Get your first real-time stream running in under a minute.
Step 1: Run the Server
The server must be running before the clients can connect.
Step 2: Start the Publisher
This demo accesses your webcam and sends the stream to your local PulseBeam server.
See the Pen publisher by Lukas Herman (@lherman-cs) on CodePen.
Step 3: Start the Viewer
Open this in a new browser tab to subscribe to the video stream.

Alternative Server Setup
If you prefer not to use Docker, you can run the server from a binary or source code.
Roadmap
We're just getting started. See what's planned for the future.
Prototype
Working basic audio/video Rust SFU + browser demos.
Enhanced Media Support(Current)
Bandwidth estimation, data channels, and video simulcast.
Core Stability
Simulation testing, end-to-end tests, and production hardening.
Ecosystem Services
Recording agents, analytics services, and a JavaScript SDK.
Multi-Node & Scale
Built-in clustering and cascading SFU capabilities.
