What is Castos
Castos is a full-featured podcast hosting platform designed to be the central ‘homebase’ for serious creators. It offers truly unlimited storage, episodes, and downloads on every plan, meaning your hosting costs never rise as your audience grows. The platform handles RSS feed generation, automatic distribution to Apple Podcasts, Spotify, Amazon Music, and other major directories, plus provides a built-in mobile-responsive podcast website — making it easy to go from recording to published in minutes.
What sets Castos apart from other hosts is its native integration with WordPress via the Seriously Simple Podcasting plugin, which lets podcasters manage their entire show — publishing, analytics, and RSS — directly from their WordPress dashboard. On top of that, Castos offers automatic YouTube Republishing on eligible plans, converting audio episodes into video and publishing them to your YouTube channel with zero extra work. Automated transcription, embeddable players, and IAB-aligned analytics round out the content management toolkit.
For monetisation, Castos supports dynamic ad insertion (Castos Ads), listener donations, and premium paid or private podcast subscriptions — all without taking a cut of revenue beyond standard Stripe processing fees. Private podcasting is a standout feature, enabling password-protected or invite-only feeds ideal for corporate internal communications, online course audio, or exclusive membership content. With plans from $19/month and a 14-day free trial, Castos caters to hobbyists, growing brands, agencies, and enterprise teams alike.

What makes Castos unique
Castos occupies a rare niche by combining truly unlimited hosting (no storage or download caps at any tier) with the only native WordPress integration in the industry via the Seriously Simple Podcasting plugin — meaning WordPress users can manage episodes, RSS feeds, and analytics entirely from their own domain. Add to that automatic YouTube Republishing (turning every audio episode into a YouTube video hands-free), robust private podcasting for membership and corporate use, and flat-rate pricing that never penalises growth, and Castos stands apart from rivals like Buzzsprout, Libsyn, or Transistor that charge per download tier or per show.
