Answers use saved listing facts and recorded sources.

What it does

Castopod publishes RSS podcasts and integrates sharing and audience interaction through the fediverse.

Operate an instance yourself or compare the turnkey offers. Episodes can carry structured information such as chapters, transcripts and people. The AGPL software licence is distinct from the cost of hosting, and it does not confer rights to audio uploaded by a publisher.
