Key Differences
Pricing Model
castopod: Castopod is entirely free and open source.
ghost: Ghost is a paid product starting at $15/month (Starter plan, billed yearly) with self-hosted and managed-hosting options.
This determines whether there is any recurring cost at all for running the platform.
Content Format Focus
castopod: Castopod is built specifically for podcast/audio hosting under Podcasting 2.0 standards.
ghost: Ghost is built for written publishing -- blogs and email newsletters -- with a narrower feature set than a general-purpose CMS like WordPress, per its own documented con.
The two tools target fundamentally different media formats, so picking the wrong one means rebuilding on another platform later.
Monetization
castopod: Not documented -- no built-in payments or membership features are listed for Castopod.
ghost: Ghost has built-in memberships and paid subscriptions, letting creators charge readers directly without a separate payments integration.
Creators who want to charge for content need this natively rather than bolting on a third-party payments tool.
Hosting Flexibility
castopod: Castopod requires self-hosting; there is no official managed hosting option from the Castopod team.
ghost: Ghost can be self-hosted or run on Ghost's own managed hosting.
Buyers who don't want to run servers have an out with Ghost but not with Castopod.
Integration Ecosystem
castopod: Not documented beyond Castopod's open, auditable source code.
ghost: Ghost integrates with Mailchimp, Discourse, Buffer, Pinterest, Geckoboard, Unsplash, and more.
A wide integration library reduces the need for custom glue code when connecting marketing and community tools.
Ghost(Pro) Business and Enterprise tiers are considerably pricier than many newsletter-only competitors
Smaller plugin/theme ecosystem than WordPress
Member limits on lower Ghost(Pro) tiers can require upgrading as an audience grows
Use Cases
Choose castopod: Castopod fits podcasters who want free, self-hosted, standards-based (Podcasting 2.0) hosting and are willing to manage their own infrastructure.
