Live stream to millions.
Get started in minutes.

We make high-quality live streaming easy, so you can focus on building your product.

Developer-friendly APIs

With clean documentation and straightforward onboarding, you don’t have to be a video expert to build live streaming into your web or native applications.

Worry-free scaling

Whether you're serving a few dozen streams or a few million, we grow with you. We handle scaling so you don't have to.

Faster time to market

What took months now takes minutes. Let us do the technical heavy lifting and take weeks off your launch time.

Stream live from any source with RTMP

We use RTMP for accepting live broadcasts, and HLS for output streams. This gives your application the ability to stream from a mobile app, broadcast software, or hardware encoder and broadcast to any device.

Broadcast to your favorite social media platform

Let your users rebroadcast to a specific platform with Live Simulcasting. We make it easy to restream to: Facebook, YouTube, Twitter, Twitch, and more.

Transition from live to VOD seamlessly

Live streams are automatically recorded and available immediately after the event with no waiting for additional processing or complex workflows to manage. The moment a broadcast ends, we make your asset available to stream.

Pay only for what you use

We don’t charge you for creating live streaming endpoints and stream keys. This makes it easy to support your users. With a unique live “stream key” for each of your users, we’ll send you a webhook so you can respond appropriately whenever they go live.

Live Video, in seconds.

Use the Mux Video API to connect your streamers with your video players.
