Real-time & WebRTC: Engineering capability

Video calls, live audio, screen sharing and multiplayer state, end-to-end encrypted and tuned for low latency.

Our role: Architecture, media servers and clients.

Stack: WebRTC, SFU, SFrame E2EE, TURN / STUN, WebSockets.

Calls: Up to 1080p, E2EE

Latency: Sub-200 ms targets

Overview

Video calls, live audio, screen sharing and multiplayer state, built on WebRTC and WebSockets.

Encrypted calls

Per-frame end-to-end encryption with insertable streams and SFrame, keys exchanged with ML-KEM + X25519. The server only relays ciphertext.

Media servers

SFU topologies for group calls, simulcast and adaptive bitrate, TURN/STUN for hard networks, recording when you need it.

Real-time state

Authoritative game and app servers on WebSockets and Colyseus: lobbies, presence and sync for thousands of concurrent players.
