Everything to publish, embed, and actually understand your show.
casterbase replaces the guesswork of download counts with real listening behavior — second by second.
Retention + replay heatmap
See the exact moment listeners drop, rewind, and replay. Every bar is a second someone chose to hear again.

One feed for Apple, Spotify, and everywhere else. Publish once.
Embeddable player

Synced transcripts
Auto transcripts and chapters that scroll along with the audio.
Clip & share
Turn a hot moment into a shareable clip link in two clicks.
Downloads tell you nothing. Retention tells you everything.
A green curve for who's still listening, bars for where they rewind. Find your best minutes, cut the dead air, and write cold opens people actually stay for.
