WebRTC (Web Real-Time Communication) has quickly become the backbone of modern, interactive live streaming. From video conferencing and live auctions to online betting, e-learning, and live shopping, WebRTC is powering experiences where every millisecond counts.
Unlike traditional streaming protocols, WebRTC is the only solution that consistently delivers sub-second latency (under 500ms) while maintaining high quality and broad compatibility. Because it’s natively supported by modern browsers, your audience doesn’t need to download extra apps or plugins—just click and stream.

What is WebRTC?
WebRTC stands for Web Real-Time Communication. It’s an open-source streaming protocol and set of APIs designed to enable direct, real-time audio, video, and data transfer between browsers and devices.
- HTML5 compatible – Works seamlessly in modern browsers.
- Plugin-free – No extra software required for end users.
- Cross-platform – Supported by Chrome, Safari, Firefox, Opera, and more.
By embedding WebRTC directly into your solution, you can deliver an interactive, ultra-low latency streaming experience that keeps your audience engaged in real time.
To learn on a deeper level how peer-to-peer connections and signaling operate, read more about how WebRTC works.
Why WebRTC Video Streaming Is Game-Changing
Traditional streaming protocols comparison shows that protocols like HLS can introduce delays of 10–30 seconds. In contrast, WebRTC streaming delivers video in 0.2–0.5 seconds, making it ideal for interactive use cases where instant communication is critical.
Key Advantages of WebRTC Video Streaming
- Ultra-Low Latency – Real-time streaming with ~0.2–0.5 seconds delay.
- Device & Platform Independence – Works across browsers, mobiles, and desktops.
- High-Quality Audio & Video – Adaptive to changing network conditions.
- Secure & Reliable – Encrypted streams for privacy and protection.
- Easy Scalability – Scale WebRTC to thousands without disruption.
- WebRTC Data Channels – Exchange real-time data (chat, scores, bids, commands) alongside video.
RTMP to WebRTC Migration: Why It’s Essential
The end of Flash and RTMP has left many projects in need of modern replacements. Adobe officially stopped supporting Flash Player, making RTMP an outdated and insecure choice for streaming.
If your project requires ultra-low latency, migrating to WebRTC is not just recommended—it’s essential. WebRTC provides the only reliable solution for sub-second live streaming at scale.

FAQs
What makes WebRTC different from other streaming protocols?
WebRTC is designed for real-time communication, delivering video and audio with sub-second latency (~0.2–0.5s). Unlike HLS vs WebRTC comparison shows, HLS or DASH have delays of 10–30 seconds, making WebRTC ideal for interactive applications like video conferencing, live auctions, and gaming.
Does WebRTC require plugins or special software?
No. WebRTC is natively supported in modern browsers (Chrome, Safari, Firefox, Edge, Opera). End users can stream directly without installing additional apps or plugins. Check out our WebRTC publish and play sample to see how easy it is.
Can WebRTC handle large-scale live streaming events?
Yes. With solutions like Ant Media Server, WebRTC servers can scale from a few participants to hundreds of thousands of viewers through adaptive streaming, clustering, and cloud deployment.
How secure is WebRTC video streaming?
WebRTC uses end-to-end encryption (DTLS-SRTP) for all video, audio, and data channels, ensuring secure real-time communication.
What are WebRTC Data Channels used for?
Data channels allow real-time exchange of non-media data such as chat messages, bidding values, gaming inputs, or scores—making experiences more interactive. See our WebRTC data channel sample in action.
Why should I migrate from RTMP to WebRTC?
RTMP relied on Adobe Flash, which is now obsolete. WebRTC is the modern replacement that offers ultra-low latency, better security, and broader compatibility, making it the best choice for real-time streaming. Learn about determining your latency requirements.
How does Ant Media Server improve WebRTC streaming?
