◆ the safety check for AI-built apps

You vibe-coded an app in an hour.
Now don't ship it naked.

Claude, Cursor and Lovable are great at building your app — and terrible at telling you it's leaking your API keys, that your database is wide open, or that it crashes on an iPhone. tofu finds what'll bite you before you go live, and writes each fix for your AI coder to paste. No jargon.

Reads your project like a senior team would, right before launch. Your code is never stored.

“Shipped” is not the same as “safe to ship.”

We scanned 22 real apps people vibe-coded with Lovable, Bolt, v0 and Cursor and pushed to GitHub. Here's what their AI quietly left behind.

50%

of the apps with a real backend had a “can wreck you” hole (6 of 12)

of all 22 came back genuinely clean — two were just empty starter templates

How it works

Three steps. You never touch a line of code.

Step 01

Point it at your project

Drop the folder or connect the repo. Doesn't matter which AI built it — Lovable, Bolt, v0, Replit, Cursor, Claude. Your code never leaves with us.

Step 02

A team of experts reviews it

A security engineer, a reliability engineer, a designer, and a product reviewer each go over your app in seconds — and rank the real landmines, worst first, in plain English.

Step 03

Paste the fix, done

Every issue comes with a ready-made prompt. Paste it into the same AI coder you already use, and it fixes it. Re-scan to confirm.

🔒

Security & data

leaked keys, open databases, logins you can walk past

🔌

API & keys

exposed keys, endpoints anyone can drain

🖥️

Frontend & reliability

crashes, blank screens, lost progress

🎨

UI / UX

accessibility, mobile, the conventions people expect

⚡

Performance

slow loads, things that break as you grow

🎮

Product & integrity

exploits, cheats, and “it doesn't actually work”

The things people ask first.

Is my code safe with you?

Your code is scanned and thrown away — we don't store it. And any secret we find is shown as “a key in this file,” never the actual value. (Making sure other people's apps don't leak your data is literally what we do.)

Do I need to know how to code?

No. That's the whole point. tofu explains every issue in plain English, tells you which words mean what, and writes the fix so your AI coder can just do it.

Which tools does it work with?

Anything. Lovable, Bolt, v0, Replit, Cursor, Claude Code, or hand-written — if it's a project folder or a repo, tofu can read it.

How accurate is it?

The scariest issues (leaked keys, open databases) are caught by exact rules, so there are no false alarms on those. The rest is reviewed by AI and ranked by how badly it can actually hurt you — and if your app is genuinely fine in an area, we tell you it's fine instead of inventing problems.
