Castos

Podcast host with unlimited shows, episodes and downloads on every paid plan, from $19 a month.

77/100

#2 of 10 podcast hosts
Facts checked 9 Oct 2026

In short

Castos suits creators who want no limits on shows, episodes or downloads and plan to leave or arrive without losing listeners, since it documents import, a 301 redirect and file download1,6,7,8. Transcripts and private feeds come with the entry plan, and paid plans can request dynamic ad insertion1,12. The catch: there is no free plan, and video hosting and larger teams cost more1,11.

Best for: Creators who want no caps and a WordPress-friendly host.
