Go Stream Cast – Live Streaming App for Android (Flutter: YouTube, Facebook & RTMP Multistream)

Go Stream Cast - go live on YouTube, Facebook and any RTMP server

Go Stream Cast is a complete live streaming app for Android (Flutter + Kotlin source code). With only a stream key, your users go live on YouTube Live, Facebook Live and any RTMP(S) server - Twitch, Kick, Restream or their own server - and on several platforms at the same time.

They stream a picture with music, a video file, a YouTube or Facebook link they have the rights to, a direct m3u8 / mp4 link or an audio / radio stream with a cover - with logos, animated GIFs, text watermarks and a news banner with a moving ticker on top. A hardware engine (the phone's video chip) shows a live preview and keeps streaming when the app is closed. You earn with VIP subscriptions through Google Play.
