ASSESSMENT GUIDE
Substack and Ghost: compare the full publishing cost
Ghost is worth assessing when you want a publication on your own domain, a subscriber list you can export and more control over the site. Moving also means taking responsibility for services that Substack currently operates for you.
When to explore it
You publish regularly, understand how readers find you and want control over your website and memberships. The decision becomes more interesting as paid-subscription revenue grows, but revenue alone does not establish a saving.
When keeping the current tool may make sense
Keeping Substack may make sense if its reader network drives valuable discovery, your publication is free, or you want someone else to run the publishing infrastructure. Ghost does not recreate the Substack reader network.
Costs that belong in the comparison
Substack says free publishing has no platform charge. Paid publications pay a 10% platform fee plus payment-provider fees. For self-hosted Ghost, compare hosting, Mailgun delivery, payment processing, backups, maintenance and migration. Payment fees do not disappear when platform fees change.
What to verify before a move
- Separate free readers, paid members and the revenue that actually incurs platform fees.
- Inventory posts, images, redirects, domains and subscription records before migration.
- Verify payment migration, member login and newsletter delivery with a small rehearsal.
- Test exports and recovery, and agree who handles updates and delivery problems.
Is Ghost free to run?
The software is available under MIT, but a working publication needs hosting and may need paid email delivery, processing and ongoing care.
Will moving create savings?
That depends on current platform fees, replacement services and migration cost. Free Substack publishing starts at zero expenditure, so adding hosting is an added cost.
