Cursor, Bolt and Claude write code that runs — and quietly leaves API keys in the open, logins that don't check, queries that can be hijacked. Paste your code, get the problems in plain English, with the exact fix to paste back. Two minutes, free.
Straight from Cursor, Bolt, Lovable or your editor. No account, no install.
Your code goes from your machine directly to the AI reviewing it — never to us. We couldn't store it if we wanted to: there's no server here.
Every finding comes with the corrected code. Paste the fix back into your AI editor, re-check, ship.
The free version uses your own Claude API key (a review costs you about a cent, paid to Anthropic — not to us). If you'd rather not touch API keys at all, Preflight Pro includes reviews with no key setup — it's coming to the tool page shortly.
Small, fully-typed TypeScript codebases we built for our own work with the Claude API. Buy once, own the code.
ShipClearance is a one-person studio. Preflight exists because the same story kept repeating: someone builds an app with an AI editor, ships it, and gets burned by a problem they couldn't have seen — a key left in the code, a login that never checked. The fix isn't "learn security"; it's a two-minute check before you ship.
