Best for ghost: Publishers who want self-hosting flexibility, a flat predictable monthly cost, and named integrations with existing email marketing, community, and analytics tools (Mailchimp, Discourse, Buffer, Pinterest, Geckoboard, Unsplash).
Best for Substack: Writers starting a paid publication with no upfront cost who want to tap Substack's built-in reader network for discovery and publish beyond text — podcasts, video, and live video — without managing hosting.

Key Differences
Monetization structure
ghost: Charges a flat platform subscription fee starting at $15/month (Starter plan, billed yearly); no revenue-share cut is documented.
Substack: No upfront platform fee to start, but Substack takes a 10% cut of a writer's paid subscription revenue, on top of separate payment-processing fees.
Ghost's cost is fixed regardless of subscriber revenue; Substack's cost scales with how much subscription revenue a writer earns.
Built-in discovery network
ghost: No built-in reader/discovery network is documented; growth relies on the publisher's own channels and integrations.
Substack: More than half of new subscribers come from Substack's built-in network and recommendations rather than outside promotion.
Substack offers a documented distribution advantage for new writers; Ghost requires publishers to drive their own traffic and use integrations like Mailchimp/Buffer for growth.
Hosting flexibility
ghost: Open source at its core; self-hostable or run on Ghost's own managed hosting.
Substack: No self-hosting or open-source option is documented; it's a single hosted platform.
Ghost gives technical publishers control over infrastructure; Substack keeps hosting entirely on its own platform.
Named integration ecosystem
ghost: Wide integration library named explicitly: Mailchimp, Discourse, Buffer, Pinterest, Geckoboard, Unsplash, and more.
Substack: No third-party integrations are documented; the facts emphasize built-in ownership and the reader network instead.
Ghost publishers can plug into existing marketing/community stacks; Substack's value proposition documented here is ownership and discovery rather than external tool integration.

Pros & Cons
ghost
Pros
Fully open source (MIT license) with a free self-hosting option and no vendor lock-in
Native paid membership and newsletter monetization without needing extra plugins
Nonprofit governance structure makes the platform structurally resistant to acquisition or shutdown
Lean, fast, publishing-focused architecture compared to general-purpose CMS platforms
Headless API supports fully custom frontends for developer teams
Cons
Less flexible than WordPress for building non-publishing websites (e-commerce stores, complex layouts)
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
Substack
Pros
Free to start with no upfront cost to launch a publication
Writers retain ownership of their content and subscriber list, including email addresses
Built-in payments and discovery network remove the need for separate tools
Supports multiple formats (newsletter, podcast, video) under one publication
Large and active reader ecosystem via Notes and cross-publication recommendations
Cons
10 percent platform fee plus Stripe fees can be significant for high-earning publications
Limited design customization compared to standalone website builders
Content moderation controversies have drawn criticism for allowing extremist newsletters
No self-serve control over payment processor -- tied to Substack's Stripe integration
Revenue depends heavily on subscriber willingness to pay, which varies widely by niche
Use Cases
Choose ghost: Publishers who want self-hosting flexibility, a flat predictable monthly cost, and named integrations with existing email marketing, community, and analytics tools (Mailchimp, Discourse, Buffer, Pinterest, Geckoboard, Unsplash).
Choose Substack: Writers starting a paid publication with no upfront cost who want to tap Substack's built-in reader network for discovery and publish beyond text — podcasts, video, and live video — without managing hosting.
Need both: Publishers testing distribution channels may run both: a Substack newsletter to benefit from its built-in reader network for discovery, alongside a self-hosted Ghost site using integrations like Mailchimp or Buffer for owned-audience marketing — though most publications settle on one as their primary platform.
