Why People Look For A Libsyn Alternative

Upload limits turn growth into a tax.

  • Publishing more shouldn’t mean paying more.
  • Multiple podcasts shouldn’t require multiple accounts.
  • A longer episode (or higher bitrate) shouldn’t force a plan jump mid‑month.

Castos removes the ceiling so you can publish on your schedule, not your host’s.
