Real-Time Video Without the Lag

Sub-second latency. Global scale. Built for developers. Stream's APIs and SDKs give you full control over live voice and video experiences. Scale to millions on a global edge network with code you actually want to work with.

Video Solutions for Every Use Case

Stream’s video stack is built to be flexible, so you can move fast, customize freely, and scale without limits.

AI Voice Agents

Build voice agents using our out-of-the-box support for OpenAI Realtime or Gemini Live, and the second allows for a more traditional Speech-to-Text (STT) -> LLM -> Text-to-Speech (TTS) pipeline.

Video AI Agents

An open-source Video AI framework that ships with Stream Video as its default low-latency transport and is powered by our global edge network, but also allows developers to bring any edge layer they like.

Video Calling API

Build in-app video calling in days. Stream runs hundreds of servers around the world, so you can focus on what’s unique to your app. Start small and scale to millions of users.

Whether you need simple 1:1 calls or a feature-rich experience like Telegram, Stream delivers crystal-clear audio with unmatched reliability and scale.

Livestreaming API

Build ultra-low-latency live streaming supported by Stream's global edge network to broadcast from your phone or RTMP and scale to millions of participants.
