How does Castos compare to other podcast hosting platforms?
Most hosts cap your downloads, charge more as your audience grows, or lock you into their platform. Castos gives you truly unlimited storage and downloads at one flat price — with built-in WordPress management and automatic YouTube publishing.
Two channels most hosts can't touch
Castos is the only podcast host with a native WordPress plugin and automatic YouTube publishing — so your show lives where your audience already is.
Industry-leading WordPress integration
The top-rated Seriously Simple Podcasting plugin keeps your RSS feed, episode management, and analytics under your own domain. No coordinating between platforms — full control from your WordPress dashboard.
A better way to monetize your show
Castos Commerce lets you charge for access to some or all of your episodes — premium subscriptions, private feeds, and listener donations, all without intrusive ads or chasing sponsors.
Free white-glove migration
Moving from another host? Our team migrates your audio, episodes, and RSS feed for you — typically with no downtime and no broken links for existing subscribers. 10 episodes or 1,000, we handle it.
Carbon-neutral hosting since day one
Castos has been carbon neutral since founding. Our infrastructure runs on AWS Oregon (a carbon-neutral facility), and we commit 1% of revenue to next-generation carbon removal.
Automatically publish to every major directory
See What Our Customers Have To Say
Castos and the Seriously Simple Podcast plugin have made podcasting so much easier for me and our team. Since switching to Castos, everything is managed on the backend of our website which saves so much time and limits potential mistakes. They migrated over 100 episodes from our old platform without any downtime.
