WebRTC

What is it?

WebRTC is the technology that makes real-time, two-way video in the browser or app possible — with delay so small (under a second) that people can actually talk to each other naturally. It's what video calls are built on, and in streaming it's the magic behind "invite a guest with just a link."

Practical example

A host using StreamYard sends a guest a simple link. The guest clicks it on their laptop — no app install, no stream key — and ten seconds later they're live on the show, having a normal back-and-forth conversation with the host. That instant, conversational experience is WebRTC.

Key things to know (non-technical)

• Its superpower is ultra-low delay, which makes real conversation possible.
• Works directly in browsers and mobile apps — no setup for guests.
• The trade-off: it's more expensive and complex to run at very large audience sizes, so platforms usually use it for the participants (host + guests) and a different method (like HLS) for the audience.
• Also powers interactive formats: live auctions, Q&A with fans on screen, co-hosted talk shows.

In Tupic Live

WebRTC is the natural foundation for Tupic Live's "invite a guest" and co-host features — letting a creator run a talk-show format where guests join from a simple link, just like a TV studio bringing a remote guest on air.
