These free utilities cover the small jobs around content creation. For continuous channels and team production, Upstream also supports 24/7 live streaming, pre-recorded live streams, multistreaming, and Live Studio broadcasts.

For this tool, the closest next step is Live Studio, so that workflow appears first below.

Invite speakers, share screens, manage scenes, and add branded overlays for podcasts, webinars, interviews, and launches.

Upload once, build a playlist, and let Upstream run continuous live playout without OBS, a VPS, or an always-on computer.

Turn recordings into scheduled live streams, premieres, loops, and recurring broadcasts from the same cloud workflow.

Go live to YouTube, Twitch, Kick, Facebook, Rumble, and custom RTMP without making your upload connection carry every copy.
