Plus standard Stripe processing. No tiers, no monthly fees, no surprises. You see the exact payout before you publish.
Get a personal storefront with themes and custom blocks. Link to it from anywhere.
What’s the platform fee?
Flat 10% on every sale. Stripe’s payment processing fee (2.9% + $0.30) is separate and comes out of your payout. You’ll see the exact breakdown when you set your price.
Do I need to be a “real” developer?
No. If you vibecoded a tool with Claude, Cursor, or any AI assistant, it counts. If it works and someone wants it, you can sell it here.
Do I need a Stripe account?
Yes. Stripe handles all payments and payouts. You’ll connect your Stripe account when you set up your first product.
What’s the difference between Open Shelf and Closed Shelf?
Open Shelf products can be forked and improved by other developers (you get 20% royalty on forks). Closed Shelf products are yours alone — no forks allowed.
Where is the software hosted?
You host it. Most sellers link to a GitHub repo or release page. DuckSubs handles the storefront, payments, and delivery links.
Just vibecoded your first tool?
We wrote a guide that goes from zero to your first sale.
