What it is
Castream is a streaming platform for broadcasting mobile or desktop streams to several destinations at once. It supports YouTube, Twitch, Facebook, Facebook Pages, TikTok, Instagram, LinkedIn and custom RTMP destinations. YouTube, Twitch and Facebook connect through OAuth; TikTok, Instagram, X, LinkedIn and custom destinations use an RTMP URL and stream key. Streamers can view and respond to chats from connected platforms in one inbox, with options for chat overlays, lower thirds, live badges and custom text. The iOS and Android apps support screen capture, and Android can show a live camera overlay on a shared screen. Desktop streams from OBS Studio or other RTMP-compatible software can be redistributed to connected destinations. Castream says streams are recorded automatically for review, download, sharing or replay. AI tools generate titles and descriptions, analyze audience sentiment and suggest content. The free plan is free and allows two simultaneous destinations, 720p mobile at 1.2 Mbps and 720p desktop at 2 Mbps, with sessions up to five minutes and a watermark. Creator costs $9.99 a month; Pro costs $16.99 a month.
