<a href="https://developers.cloudflare.com/stream/webrtc-beta/" target="_blank" rel="noopener">Stream WebRTC support ↗︎</a> lets you deliver high quality live video to thousands of concurrent viewers in milliseconds. WebRTC is compatible with native Web APIs and standard protocols, so creators can <a href="https://developers.cloudflare.com/stream/examples/browser-based-webrtc/" target="_blank" rel="noopener">go live from a browser ↗︎</a> without needing a separate broadcast application. This powers platforms to build custom experiences with deep feature integration for creators as well as viewers. Here's how to get started with a Stream live input and a browser. Usage-based billing for WebRTC begins today, October 15, 2026 and follows the standard rates for minutes of video delivered. Refer to <a href="https://developers.cloudflare.com/stream/pricing/" target="_blank" rel="noopener">pricing ↗︎</a> for rates. <div tabindex="-1" class="heading-wrapper level-h4"><h4 id="what-changed">What changed</h4><a class="anchor-link" href="#what-changed"><svg width="16" height="16" viewBox="0 0 24 24"><path fill="currentcolor" d="m12.11 15.39-3.88 3.88a2.52 2.52 0 0 1-3.5 0 2.47 2.47 0 0 1 0-3.5l3.88-3.88a1 1 0 0 0-1.42-1.42l-3.88 3.89a4.48 4.48 0 0 0 6.33 6.33l3.89-3.88a1 1 0 1 0-1.42-1.42Zm8.58-12.08a4.49 4.49 0 0 0-6.33 0l-3.89 3.88a1 1 0 0 0 1.42 1.42l3.88-3.88a2.52 2.52 0 0 1 3.5 0 2.47 2.47 0 0 1 0 3.5l-3.88 3.88a1 1 0 1 0 1.42 1.42l3.88-3.89a4.49 4.49 0 0 0 0-6.33ZM8.83 15.17a1 1 0 0 0 1.1.22 1 1 0 0 0 .32-.22l4.92-4.92a1 1 0 0 0-1.42-1.42l-4.92 4.92a1 1 0 0 0 0 1.42Z"></path></svg></a></div> While in beta, Stream’s WebRTC support was rebuilt from the ground up to leverage <a href="https://developers.cloudflare.com/realtime/" target="_blank" rel="noopener">Cloudflare Realtime ↗︎</a>’s primitives for stability and scale while managing these components in Stream’s familiar, unified API that makes it easy to build. We also adopted the latest WHIP and WHEP protocol standards for Trickle ICE, server and client offer modes, and counter-offer support for improved player library compatibility and network traversal adaptability.
