Launching early 2027

A pre-launch check for apps built with AI.

Scan your code and work through the pre-launch checks non-technical founders regularly miss. Then get a readiness score with fixes you can export to your AI coding tool.

## 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.

Who checks your app before launch?

Not all app reviews are created equal. Different ways to check. Different trade-offs

Your AI tool
Good for
Building fast and making fixes.
Trade offs
It only checks what you ask, and won’t raise what you didn’t know to ask about.
Hire an engineer
Good for
Judgement, experience, and someone who'll ask the right questions.
Trade offs
Cost, and good engineers are hard to find on short notice.
Built for non-technical founders
LoupeKit
Great for
Automated checks built by experienced software engineers, available 24/7 with no technical background required.
Trade offs
Not a replacement for an engineer on complex problems.

How it works

From your repo to a readiness checklist, in four steps.

Step 1

Connect your app

Pick your app’s GitHub repository, and LoupeKit will scan it with read-only access.

Each fix is a clear prompt, created for an AI to understand exactly what to change and why.

Your AI coding tool

You pasted loupekit-fixes.md## Fix: Secret key may be exposed in browser code …

Done. I moved the key to a server-side environment variable and switched the browser code to the public anon key. Rotate the old key in Supabase when you can.

Ask your AI tool…

Step 4

Rescan

Once your fixes are completed, rescan to verify them and get one step closer to launch 🚀

Two kinds of checks. One readiness score.

LoupeKit scans your code and identifies issues that can be solved with AI.

It then combines these with tasks that can’t be solved or validated with AI - to form your pre-launch checklist.

Questions

Something else on your mind? Email us at [email protected].

When can I use LoupeKit?

We’re planning to launch in early 2027. Join the waitlist and we’ll email you when it’s ready.

Which apps does it work with?

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.

What access does it need to my code?

Read-only access to the GitHub repository you choose. LoupeKit never changes your code.

What can’t it check?

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.

How do the fixes work?

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.

Do I need to know how to code?

No. Everything is explained in plain English, and your AI coding tool makes the changes.
