Our verdict
Castos is a podcast hosting platform with deep WordPress integration (via Seriously Simple Podcasting plugin), private podcast support, and automatic YouTube republishing. Best for WordPress podcasters and businesses with internal podcasts. The main caveat is smaller user base than Buzzsprout/Podbean and fewer AI features.
