## Fix: Secret key may be exposed in browser code Area: Security & privacy File: src/lib/supabase.ts:4 A Supabase service role key appears in code that runs in the browser. Anyone visiting your app could read it and get full access to your database. 1. Move the key to a server-side environment variable. 2. Use the public anon key in browser code instead. 3. Rotate the old key in your Supabase dashboard. 4. Scan again to confirm.
From your repo to a higher readiness score, in six steps.
Pick the repository your app lives in. VibeCheck only reads it, and never changes your code.
VibeCheck reads your code and looks for common launch risks.
Each issue is explained in plain English: what we found, why it matters and where it is.
Answer a short checklist for things a scan can’t see, like backups.
Copy the fixes into your AI coding tool and let it make the changes.
Scan again to confirm the fixes and see your score go up.
A readiness score for each area, and every issue explained with the steps to fix it.
## Fix: Important pages may load slowly Area: User experience Type: Checklist You haven’t checked the speed of your sign-up page or main feature yet. Slow pages lose people before they ever sign up. 1. Run each page through Google PageSpeed Insights (free). 2. Paste any red results into your AI tool and ask it to fix them. 3. Tick each page off in your checklist.
Every issue is explained in plain English: what we found, why it matters and where it is. When you’re ready, export the fix as Markdown for your AI coding agent.

At launch, JavaScript or TypeScript React apps on GitHub, including ones built with Vite, Next.js or TanStack Start. Lovable apps, for example, are built this way. Things a code scan can’t see, like your hosting or database settings, are covered by the guided checklist.
Read-only access to the GitHub repository you choose. VibeCheck never changes your code.
It looks for common launch risks, not every possible problem. Some checks rely on your own answers to the checklist. It can’t guarantee your app is secure or ready to launch.
Each issue comes with plain-English steps and a Markdown version for your AI coding tool. Paste it in, let your tool make the change, then rescan to confirm it’s fixed.
No. Everything is explained in plain English, and your AI coding tool makes the changes.
