This article will walk you through the key features of Castr’s livestreaming features and how to set up a new project within minutes.

Livestream and Multistream in Castr — What Are the Differences?

Castr’s terms for our livestream and multistream plans can be confusing at first. No worries, we are here to help.

Multistream, or simulcast, is streaming to multiple platforms at once, via stream keys and custom RTMP servers. With Castr, you have Facebook Pages and Groups, YouTube, Twitch, Periscope, and more than 30 other social media choices to livestream simultaneously.

To read more about multistreaming using Castr, you can visit our docs.

Livestream, on the other hand, offers you with an embed player URL / iFrame code for putting the stream on your website and to OTT players. That means Castr’s Livestream expands your reach and flexibility to a wider audience with embedding the video player to any website of your choice. If you need to multistream and embed videos on your own website, our livestream plan is your go-to.
