SHIPCHECK — a pre-flight check for vibecoded apps
You built it with AI. It runs. And you still haven't posted the link — because you're not sure what a stranger could do to it. ShipCheck runs five plain-language checks against your live, running app, shows you proof of anything broken, fixes it on its own branch, and proves the fix works. You review. You click merge. Then you ship.
One-time purchase · Runs in Claude Code · Never touches your live app · Never merges anything

You built a real app with AI. It works. The demo impressed your friends. And the launch post is still sitting in drafts — because somewhere in the back of your head a voice keeps asking:
What if someone opens the database? What if a stranger runs my OpenAI bill to $400 overnight? What if the payment form just… believes anyone who says "I paid"?
That voice is right to ask. AI-written apps ship with the same handful of holes, over and over: a master key sitting in the frontend, a database that answers strangers, a webhook that trusts anyone. None of them show up in a demo. All of them show up in week one of real users.
A security scanner won't catch most of them — it can't log in as two different people and try to read the wrong one's data. ShipCheck can. That's the whole point.
Not a code lint. ShipCheck probes the deployed thing your users will actually touch.
Could a total stranger, with no login, read data that should be private — or find a master key sitting in the open?
Proof: "3 rows including email, plan — returned to an anonymous request."
Logged in as one user, can you read another user's orders, messages, profile? The leak automated scanners can't find — it takes two real accounts.
Proof: "Account A requested Account B's orders — and got them."
Is there an AI or paid-API endpoint a stranger could hammer, running up a bill on your card?
Proof: "15/15 requests answered, no slowdown. ~$200 per 10,000 requests, billed to you."
Could someone get your paid product for free by sending a fake "payment succeeded" message — or edit the price in their browser?
Proof: "Forged, unsigned webhook accepted. Product granted. No payment existed."
Share preview, robots.txt, sitemap, 404, security headers — or does your launch link post as a blank grey box?
Proof: "No preview title, description or image. Your launch post is invisible."
Verdicts are honest: pass · BLOCKER · not verified. When ShipCheck can't test your stack, it says so — it never guesses "OK".
ShipCheck runs the exact probe and captures redacted evidence. The "before" picture. No "this is probably an issue."
The smallest safe change, on fix/shipcheck-<check>-<date>. Never on main. Never on your live app.
The fix is re-tested on a throwaway preview build. Same probe, broken → fixed, before your eyes. If the fix doesn't hold, ShipCheck reverts it and says so — it never pretends.

Ship one app? ShipCheck. Ship every month? Superproject.
Yes. ShipCheck is a Claude Code plugin — you run /shipcheck in your project, it does the rest. Works with any Claude Code plan.
No. Live traffic is read-only plus a handful of capped, self-cleaning probes (max ~15 requests, stops at the first pushback), and only after you confirm ownership. Fixes happen on branches and preview builds, never on production.
You'll get the universal checks (data exposure scan, discoverability, code-level cost review) and honest "not verified" for the rest. Supported stacks are growing; you'll get those updates.
Then you ship with proof instead of hope — that's the good outcome. If you feel you didn't get your money's worth, 14-day refund, no questions.
Scanners read from outside. ShipCheck logs into your app with two test accounts and tries to read the wrong one's data, forges a payment event against your own webhook, and probes your cost brakes — the failures that actually burn first-time founders.
No. Local mode is first-class: report lands in your repo, fixes on local branches.
Five checks, real proof, fixes waiting on branches. The scary part of launching, handled in one run.
