The Problem

Great Podcasts
Don't Last

Podcast hosts shut down. Creators delete archives. RSS feeds expire. What happens to the episodes that shaped your thinking, made you laugh, or kept you company?

Feeds Disappear

Hosting platforms shut down, leaving your favorite shows inaccessible, possibly forever.

Episodes Get Deleted

Creators remove content, serial podcasts end, and networks purge archives.

CastKeeper Preserves
