Fix and launch your Cursor-built app

    You or your team built it with Cursor or Claude Code and it's grown hard to change. Senior engineers review it, fix what blocks launch, and add the structure that keeps it working, for a fixed price.

    Why Cursor apps stall before launch

    Cursor is a code editor with AI built in, so a Cursor app can use any stack. That's a strength: the code is yours, in your own repository, from day one.

    The risk is that nobody sets the rules. Each prompt solves the problem in front of it, so the same thing ends up done four ways, tests never get written, and security depends on what the AI happened to remember.

    What usually breaks in Cursor apps

    The problems we look for first. Most apps have two or three of them.

    • Four ways of doing the same thing

      Data fetching, error handling and validation look different in every file, so each change takes longer and breaks more.

    • No tests on the paths that matter

      Sign-up, payments and anything that writes data have no tests, so every release is a gamble.

    • Secrets in the repository

      API keys in the code or a committed environment file, sometimes already in the git history.

    • Hand-rolled login and permissions

      Custom auth code with gaps: tokens that never expire, routes that only check if someone is logged in, not what they're allowed to do.

    • No pipeline

      Deploys happen from someone's laptop, with no checks before code reaches production.

    How we fix it

    Review first, then a fixed quote, then the work, with a demo every week. How a rescue works

    1. 1

      We read the code first and agree the few patterns the app should follow, then bring the risky parts into line instead of rewriting everything.

    2. 2

      We add tests to sign-up, payments and data writes, remove secrets from the code and its history, and fix permissions on every route.

    3. 3

      We set up a deploy pipeline with checks, so your team, or your next AI session, can keep shipping safely.

    Prices

    The same fixed prices for every Cursor app. The review ends with a fixed quote for anything bigger.

      $149

      3 working days

      A senior engineer reads your code and tells you what stands between it and launch.

      • Written report: security, access rules, login, payments, deployment
      • A fix-or-rebuild recommendation
      • A fixed quote for the work
      • The $149 comes off any fix you book within 60 days

    • Critical fix

    Frequently Asked Questions

    Common questions about fixing a Cursor app

    Yes. The problems come from how AI-written code accumulates, not from the editor, so the review and the fixes are the same.

    Rarely. Rewrites are slow and risky. We fix what blocks launch and add structure where it pays off, and the review says plainly if a rebuild would be cheaper.

    A $149 review with a fixed quote, $249 for one blocking issue, or a launch sprint from $1,299. Larger clean-ups are quoted after the review.

    Yes. We can review pull requests, set up the patterns and pipeline, and hand them over, so your team keeps the momentum.
