What it does

Castos offers hosting, feed migration, private podcasting and integration with Seriously Simple Podcasting.

Move a show by importing its existing RSS feed, checking the imported episodes and redirecting the old feed so subscribers follow the new address. A WordPress publisher can instead manage episodes through Seriously Simple Podcasting while Castos serves the media.

Public, private and hybrid publishing share the platform, but capacity and delivery differ by plan. Private listeners receive individual feeds that can be revoked; allowances range from 100 to 500 by plan. YouTube republishing starts at Growth, while MP4 video hosting starts at Pro. Castos Ads and Commerce require an application, so hosting access alone does not establish approval for revenue tools.
