VERDICT

Should I use Castos?

The Easiest Way to Start and Grow Your Podcast - castos.com

Depends. Buy Castos if you need unlimited hosting, private/internal podcast feeds, or WordPress integration — paid plans start at $19/mo with a 14-day trial. Skip it if you want a free tier, a bare-bones starter host, or a spotless security track record — its WordPress plugins have multiple public CVEs.

Confidence

Medium. Based on 15+ public sources; several review snippets were truncated, so exact G2 rating digits and full tier pricing could not be confirmed.
