Quick answer: Who can fix an app I built with Cursor or Replit?

Vibefixr fixes Cursor- and Replit-built apps at fixed prices: a free scan, a $49 audit, or a $199 fix for up to five issues, delivered as a tested pull request within 72 hours. Typical problems include API calls to localhost or CORS errors in production, secrets missing after deploy, and database permission errors.

Cursor problems we fix most

Works locally, CORS or localhost errors live. The frontend still calls http://localhost, or the API doesn’t allow your production domain. The two causes and the fix
Server functions fail in production. A 500 or undefined values only after deploy, usually secrets that were never set live. How to check
Supabase 42501, empty data or exposed tables. 42501 · empty arrays · RLS check
Keys committed to Git. A .env or a secret key pushed to the repo. What to do first
Agent changes that broke other features. Cursor’s checkpoints can roll back an agent session, but they’re stored locally and separate from Git. Once broken changes are committed, you need a real fix. Breaking the fix loop

Replit problems we fix most

Works in the workspace, fails once published. Replit keeps production secrets in the Publishing settings (Publishing → Adjust settings → Production app secrets). Its publishing help says to check every key your app needs is set there, that the database URL points to production, and that nothing is hard-coded to localhost. Changed values take effect when you publish again.
Login redirects to localhost or a dev URL. The Supabase settings to change
Payments that don’t unlock. Webhook URLs and signing secrets that still point at the dev environment. Where it breaks

How it works

Free scan. Send us your repo and a one-line description of what’s broken. We email you the top issues we find and why they matter.
You approve the list. One issue is one distinct bug or security problem with one root cause. We agree the exact list, up to five, with you in writing before work starts.
Pull request with tests within 72 hours. Agents do the work, and a human engineer reviews and signs off the PR before you see it.
Keep building. Merge the PR and carry on in Cursor or Replit.

What we need

A GitHub repository. Cursor projects usually have one already. For Replit, connect the app to GitHub from the Git pane and push, then send us the repo link with the free scan form and a short description of what’s broken.

We request read-only access, use your code only to fix it, and delete copies after delivery. Fixes arrive as a pull request with tests, and a human engineer reviews and signs off every audit and PR.

We work with most JS/TS stacks: Next.js, React, Vite, Supabase, Firebase, Stripe, Vercel and Netlify.

FAQ

My app isn’t on Supabase. Can you still help?

Yes, if it’s built on a JavaScript or TypeScript stack. We work with most JS/TS stacks: Next.js, React, Vite, Supabase, Firebase, Stripe, Vercel and Netlify.

Do you work with Python or other backends from Replit?

Our focus is JavaScript and TypeScript stacks (Next.js, React, Vite, Supabase, Firebase, Stripe, Vercel and Netlify). If your backend is something else, mention it in the free scan request and ask before you buy.

Will you change my whole codebase?

No. We make targeted changes for the issues on the agreed list and deliver them as one pull request with tests, so you can review every line before merging.

Can I keep using Cursor’s agent after the fix?

Yes. The fix is an ordinary pull request in your repository. The tests that come with it make it easier to notice if a later agent change breaks it again.

What does Guard do?

Guard ($79/month) reviews every push to catch leaks and regressions early. It reviews code changes; it doesn’t watch uptime or your servers. Cancel anytime.
