What they are
Castos
Castos is a podcast host built for creators and teams running shows alongside a WordPress site, powered by its free Seriously Simple Podcasting plugin. Every plan includes unlimited episodes, unlimited downloads, no storage caps, and private podcasting. There is no free plan, only a 14-day trial, and several requested features like YouTube republishing sit on higher tiers.
Libsyn
Libsyn is one of the oldest podcast hosting platforms, used by independent creators and major media networks to store, distribute, and monetize audio shows. It handles RSS feed management, automatic distribution to Spotify, Apple Podcasts, and other directories, and offers dynamic ad insertion for revenue generation. The pricing tiers are based on monthly upload storage rather than total storage, which can feel counterintuitive compared to newer competitors.
