Questions, answered
Is Multistream free?
Yes. The app is free: chat, alerts, overlays, the chat bot and text to speech, connected to every platform in one app instead of a separate tool for each. It can also multistream from your PC, to as many platforms as your connection supports. Pro, at $10/mo, adds Multistream Cloud: OBS sends one stream, the cloud sends it to up to 12 platforms and keeps them live if OBS drops. Max, at $30/mo, has three times the data and up to 20 platforms.
Does Multistream work with OBS?
Yes. Multistream is built around OBS: point OBS at it once and press Start Streaming as usual. The app walks you through it and checks your OBS settings.
Can I switch from Castr?
Yes, in a few minutes: download the app, connect your platforms, and point OBS at Multistream. Your channels, followers and chat stay where they are.
Which platforms can I stream to?
Twitch, YouTube, Kick, TikTok, Instagram, Facebook, X and more, plus any RTMP or SRT server: up to 12 at once with Multistream Cloud, or 20 on Max.
