Load-aware global routing

Global control plane places users on the best edge. Sticky by session. Failover in 4 seconds.

Media + data in one path

Rust optimized servers terminate WebRTC and UDP. SRTP, FEC, and congestion control tuned for bursty workloads.

Numbers that matter

Horizontal growth with simple shard labels. Bring-Your-Own Server supported for BIG-BANG event

SDP + server picker API

Simple REST for offers, answers, and affinity. Bring your TURN if needed.

Edge UDP health

Automatic network status collector feeds real-time loss and jitter maps to the picker.

Observability first

Per-stream metrics, webhooks, and exports to your Prometheus or OpenTelemetry.

Security defaults

SRTP everywhere, key rotation, signed tokens, Blacklist, Whitelist supported

Developer ergonomics

CLI, Terraform module, and SDKs for JS, Rust, Go, and Python.

SLA backed

Reference architecture

A minimal footprint. Rust media workers handle SRTP and congestion control. Node.js signaling handles SDP, authentication, and server selection using live UDP health signals.
