WebRTC & real-time development articles

WebRTC is the technology behind almost every browser-based video call — and the hardest one to run well in production. This section collects our build notes from twenty years of real-time work: SFU and MCU architecture decisions, LiveKit, Agora, Twilio, and mediasoup compared on real pricing, scaling past a thousand concurrent rooms, and the failure modes that only show up under load. If you want the full picture first, start with the WebRTC architecture guide for production systems. If you need a team to build it, see our WebRTC development services.
