Our verdict on Caster.fm
Caster.fm is an internet radio hosting platform for community stations, religious organizations, schools, independent DJs, and professional radio operators. It combines Icecast-based streaming with live DJ broadcasting, playlists, scheduling, listener analytics, recording, podcast hosting, RSS publishing, and a radio website CMS. Web DJ broadcasting is available through a browser, while live DJs can broadcast through Icecast or Shoutcast software.
The freemium structure gives smaller broadcasters a way to start with the Free Cloud plan, which includes an Icecast 2 streaming server, 400 listener slots, streaming up to 96 Kbps, and a radio website CMS. Cloud Plus costs $34 per month and raises capacity to 1,000 listener slots, supports up to 128 Kbps streaming, adds live stream recording, and removes advertisements. Pro Medium costs $80 per month and adds unlimited listener slots, unlimited bandwidth, Smart AutoDJ, and branded mobile apps. Pro Large and Pro Extra continue the unlimited listener and bandwidth features while adding 5 GB and 10 GB of AutoDJ storage, respectively, with 2 or 4 HLS streams.
Its strongest fit is for broadcasters that want several station operations in one service rather than a narrowly focused stream host. Smart AutoDJ, playlists, scheduling, recording and replay, real-time reports, podcast publishing, and CMS tools cover both live and automated programming. The platform also spans web, Windows, macOS, iOS, and Android, with branded iOS and Android apps available on Pro Medium. Stations needing more than the Free Cloud limits should consider paid tiers; broadcasters focused only on basic streaming may not need the broader radio toolkit. Caster.fm has supported internet radio since 2010.
