I have just discovered Castopod and I am still amazed by the depth of the Fediverse and ActivityPub protocol.
It's a platform to host audio podcast. And like with Peertube, you can follow accounts on one instance of Castopod directly through Mastodon.
As Castopod is self-hosted we cannot know. There are Castopod instances that we never heard of!
We will probably create a list where podcasters can voluntarily add their podcasts in the near future.
In the meantime you can search for "Powered by Castopod" on your favorite search engine. 😉
Bienvenue sur l'instance personnelle de Couka.
