Castopod is an open-source podcast hosting solution for everyone, that can connect to the Fediverse through the W3C ActivityPub standard (Pixelfed, Mastodon, Pleroma…). Castopod is user friendly, and allows for easy discovery everywhere. Whether you are a beginner, an amateur or a professional, you will get everything you need: you can create, upload, publish, manage server subscriptions (WebSub embedded server). You can allow users to listen to your podcast directly, but just as easily connect to commercial directories (Apple, Google, Spotify…).
Castopod Mobile is a free and open-source mobile podcast player application (GPL v3). It is a two-in-one application: a podcast player and a Fediverse client. It takes advantage of ActivityPub features for $podcasts provided by Castopod Server. The app aims to simplify onboarding to the Fediverse and serves as a template for communities building their own ecosystem with private Castopod servers and custom $mobile clients.
Castopod Plugins introduces a new modular framework allowing anyone to develop plugins for the Castopod podcast hosting platform. This brings a clean, versioned way to add custom features, improves security by slimming down the core, enables community-driven development, and helps accommodate diverse podcaster needs while supporting compliance across jurisdictions.
Podcast distribution is increasingly concentrated on platforms that intermediate the relationship between creators and audiences, extract revenue, and apply opaque recommendation systems. Creators who build an audience on one platform risk losing reach overnight through algorithm or policy changes.
Castopod returns control to podcasters: self-hosted publishing, direct listener access, and Fediverse integration via ActivityPub. Castopod Mobile lowers the barrier to joining open networks without installing surveillance-based social apps. Castopod Plugins let communities adapt hosting to local legal and safety requirements rather than accepting a single global moderation and monetization model.
