10 Wild Facts About WebRTC You Never Knew
WebRTC is everywhere, powering billions of voice and video calls daily, yet most people have no idea about its quirks. Even if you sit next to a coworker, your video call might still travel thousands of miles before it reaches them. WebRTC solves this with direct connections, saving latency, bandwidth, and energy. Google almost called it WebP2P, but the name didn’t stick, which would have made “WebP2P video calls” a less catchy phrase. Discord processes over 15 million voice connections daily using WebRTC, seamlessly, with peer-to-peer connections keeping infrastructure costs manageable.
Remarkably, WebRTC can work without internet. Local networks, Bluetooth, or QR codes can enable direct device-to-device communication, useful for offices, gaming, emergencies, and remote areas. Even in Antarctica, researchers rely on WebRTC to adjust automatically to slow, high-latency satellite connections, saving money and keeping communication alive. It also accidentally solved NAT traversal, a problem that puzzled computer scientists for decades. Google engineers built a robust solution for video calls, inadvertently revolutionizing peer-to-peer connectivity.
Your browser today can encode video better than professional hardware from ten years ago, thanks to optimized software and codecs like VP8, VP9, and H.264, allowing anyone to stream high-quality video from a laptop. When connecting, WebRTC tries dozens of paths—local IPs, public IPs, relays, different protocols, multiple ports—to ensure the call works. Most users just see a smooth connection, oblivious to the orchestrated chaos behind it. The very first WebRTC call was a Google engineer talking to themselves across two Chrome windows. It might not have been historic, but it started a technology that now drives billions of interactions.
Since launch, WebRTC has processed more video hours than all movies ever made. Millions of hours of video and voice pass through WebRTC daily, quietly shaping communication without most people noticing. It’s in your pocket right now: almost every smartphone supports it, from WhatsApp to Discord to Facebook Messenger, connecting over a billion people daily. The best part is you hardly notice it, yet it makes your calls smooth and reliable.
Why it matters
WebRTC is invisible yet powerful. It enables seamless communication, saves resources, and scales to billions of users while staying in the background. It’s a technology so fundamental it becomes unnoticed, yet it touches daily life in ways we rarely acknowledge.
