Sell your skill. Without giving it away.
A skill is the written instructions you'd give a very good assistant to do one job well. List it once — buyers run it and pay per call, get the output and never the file, so the first customer can't become your competitor.
Paste it into Claude Code, Cursor, Windsurf — any coding agent that can read a URL and edit files. The setup file walks your agent through the catalog, the key, the wallet, and a free sample run before any money moves.
Works in Claude Code, Cursor, Windsurf, Claude Desktop, Cline, any MCP client, or over plain HTTP.
Every other marketplace hands the buyer your file.
Prompt and skill marketplaces ship you a download. Once the buyer has the text, they have the whole thing — they can use it forever, hand it to a friend, or list it themselves. That's the documented reason sellers stop listing: the first sale is also the last one.
Sealed runs it instead Your skill sits encrypted on our servers. A buyer's agent sends inputs; we execute and return the output.
The file never moves Nothing in the API, the CLI, the MCP client or an error message carries your text. Output is scanned before it's returned.
You get paid per call Not once. Every run settles to your balance, and cash-out goes through a Stripe account in your name.
Keep 80% of every call.
Published on the seller page, applied uniformly, changed only going forward and only with notice.
No listing fee. No exclusivity. Export your skill whenever you want.
What it takes to put one up.
If you already have something that works — a prompt you've tuned, a process you run for clients, a method you keep reusing — it's most of the way there. Listings are screened before they go live — partly for the catalog's sake, partly because a skill that can't be run cleanly can't earn. The full terms, including what happens if we ever wind down, are on the seller page.
What a buyer actually does.
They point an agent at us — over MCP or the API — and call your skill like any other tool. Most are Hosted: inputs in, result back. Some are Connected: they work on files in the buyer's own project, inside a scope the buyer approves. Hosted hands back a result, Connected does the work in the buyer's project — and neither one ever hands over your file. They pay per successful run from a prepaid balance; failed runs charge nothing.

Buyers prepay once and set their own daily cap. A run is charged only when it succeeds — failed and leak-blocked runs never debit, and runs pause at the cap.
Being straight about the stage. The catalog is small and the buyer side is early — you'd be listing into a market that is still forming, and the honest reason to do it now is that early listings are the ones people find first. You can browse what's live before deciding, and the SEO title optimizer is a skill running on the platform today if you want to see the shape of one.
Can a buyer reverse-engineer my skill from its outputs?
Partly, and you should price that in rather than take a promise from me. Sealing stops your file being copied. It cannot stop someone studying twenty outputs and approximating what you did. Skills built on something the buyer can't reach — a dataset, an account, a feed, a judgement that depends on volume you have and they don't — hold up. Skills that are purely a clever way of phrasing something are the easiest to imitate anywhere, including here.
What do I actually keep?
80% of each settled call. The 20% platform fee is published, uniform, and not negotiated per seller. Buyers cover the payment-processing fee when they top up, so it doesn't come out of your share.
How do I get paid?
Earnings accrue to your Sealed balance from the first call. Cash-out runs through a Stripe Connect account in your name, and payouts are coming soon.
Can I take my skill back?
Any time. You can export your full uploaded content whenever you want, there's no exclusivity, and nothing stops you selling the same thing elsewhere.
What if nobody buys it?
Then you've spent the time it took to write it down and nothing else — there's no listing fee and no minimum. That's the honest downside, and at this stage it's a real possibility rather than a hypothetical.
Who's behind this?
One person. @edbuildthings — I build small tools, and I built this because I wanted to sell a skill without handing it over. Write to support@sealed.run and I'm who answers.
