Castos is a podcast hosting platform founded by Craig Hewitt in 2016 that grew out of the WordPress podcasting plugin ecosystem. It hosts unlimited episodes and shows for a flat monthly fee, with no per-download overage charges within a plan's included limits.
The platform is particularly known for its WordPress integration through the Seriously Simple Podcasting plugin, which lets podcasters publish new episodes directly from their WordPress dashboard, and for supporting agencies that manage podcasts for multiple clients from one account.
Castos automatically distributes new episodes to Apple Podcasts, Spotify, YouTube, and other major directories, and includes audience analytics covering listener location, device, and per-episode playback duration. A built-in AI Assistant turns uploaded audio into show notes, episode titles, social posts, and chapter markers. Growth-tier and above add YouTube republishing and Headliner integration for creating audiogram-style social clips, while the Pro tier adds video file hosting. Castos also supports private podcast feeds for internal company communications, course content, or paid membership audio, and provides a customizable podcast website that requires no design or development work.
Castos offers four tiers, all billed monthly with a 14-day free trial: Essentials at $19/month, Growth at $49/month, Pro at $99/month, and Castos Premium at $499/month for larger teams needing single sign-on, custom contracts, and a dedicated account manager. Each tier raises the included private-subscriber count, monthly download allowance, and transcription credits, and unlocks additional features like YouTube republishing, video hosting, and enterprise account management.
