Why AI-built apps share the same risks
AI tools are good at making an app work. They are less good at deciding who should be allowed to see what. That gap shows up in the same few places, whichever tool you use.
The usual suspects are secret keys left where visitors can find them, database tables with no rules about who can read them, packages with known security holes, and pages that never check whether you are logged in. These are patterns that are common in AI-built apps. They are not a verdict on any one tool.
Many people who build this way are not developers, so these problems are easy to miss. Each guide below explains the problems in plain English, with a rating for how serious each one usually is.

Lovable security checkMost common issue: Database tables left open because nobody set rules for who can read them.Read the guide →
Bolt security checkMost common issue: API keys placed in front-end code where every visitor can see them.Read the guide →
Cursor security checkMost common issue: API routes that work without checking who is logged in.Read the guide →
Replit security checkMost common issue: Secrets added to code instead of Replit Secrets, then shared publicly.Read the guide →
Don't see your platform?
The quick check works on any live site. Paste your website address into the free website audit and you get a result in about a minute, with no sign-up. It does not matter which tool you used to build the app.
The full check works with any GitHub repository. You connect GitHub with read-only access, pick the repositories you want checked, and remove access any time. See pricing for what each plan includes. More platform guides are on the way.
Frequently asked questions
Do I need a different check for each platform?
No. The checks are the same. What changes is where the usual problems hide and how the fix prompt is worded, so the platform guides tell you what to look for and what to paste back into your tool.
What is the difference between the quick check and the full check?
The quick check looks at your live site from the outside, needs only a website address and no sign-up. The full check connects to GitHub with read-only access and reads your code, which finds problems a website check cannot see.
My platform is not listed. Can I still use LetMeCheck?
Yes. Any live site works with the quick check, and the full check works with any GitHub repository.
Is it safe to connect GitHub?
The connection is read-only, you pick which repositories to check, and you can remove access any time. See the security page for how code is handled.
