What it really is
Castos — unlimited podcast hosting and distribution platform with deep WordPress integration.
Our take
Castos hosts unlimited podcasts, episodes and downloads on every plan, distributes them to podcast directories and offers private podcasting with password-protected feeds. It also makes the Seriously Simple Podcasting WordPress plugin. Higher plans add YouTube republishing, video file hosting, more transcripts and more private subscribers.
Why we rate it
Every plan includes unlimited podcasts, episodes and downloads, private feeds and free migration from other hosts, and the WordPress plugin lets you publish from your own site.
The catch
No free tier means you must commit to a paid plan (or trial) to evaluate the full product; transcriptions are capped and metered on lower plans; advanced analytics and video hosting only unlock at Growth/Pro.
Best for
WordPress site owners who want their podcast managed inside their CMS
Businesses running private or internal podcasts for teams or paid subscribers
High-volume podcasters who need unlimited uploads without bandwidth overage fees
Not good for
Hobbyists wanting a permanent free tier before committing
Podcasters who need advanced video-first workflows out of the box on entry plans
Non-WordPress users who want a fully branded standalone website with deep CMS control
Friction report
Time to value
Fast: a 14-day free trial and free one-click migration from hosts such as Buzzsprout, Libsyn and Transistor.
Scale breakpoint
Private subscriber limits (100–500) and monthly transcript quotas force plan upgrades as audience grows; Premium tier pricing ($499+/mo) is a steep jump from Pro.
Walled garden
Low: standard RSS feed means easy migration out; no proprietary format lock-in.
