Is my Claude Code app safe to launch?

Paste your address. We check your live Claude Code app the way a stranger would, then tell you in plain English what could cost you money, and how to fix it.

Free. No sign-up. We only look at what any visitor can already see.

Your app takes a visitor at their word about who they are.

About Claude Code

Working is not the same as safe.

Claude Code writes and changes real code in a real project from instructions in plain English. It is capable enough that founders ship whole products with it, which is precisely why the result deserves checking: the app is as safe as the code, and the code is now written faster than anyone reads it.

Where your data livesA Claude Code project can use any database. Many founder apps use Supabase, where the read-rule question applies; others use plain Postgres or something else, where your own code is the only thing deciding who may read what. We check for both.

Tools like this one write ordinary code, so a finished app carries no sign of which editor built it. That changes nothing about the check: we look at what your app actually does, not at what wrote it.

What we find

The faults we find in Claude Code apps.

Written the way your own report would write them. These live in the app Claude Code built for you, not in Claude Code’s own service, which is why only a check of your app answers it.

Could end your business

Anyone on the internet can read your customer list.

What it means for youNo login, no password, no attacker needed. Someone who finds the address copies the whole table. This is the kind of leak you may have to tell every customer about.

Costs you money

A stranger can run up your bill with nothing to stop them.

What it means for youYour app pays for every text message or email it sends, and nothing limits how often one person can set that off. The invoice is how you would find out.

The honest part

What this check cannot see.

Every scanner looks cleaner if it stays quiet about what it missed. We would rather tell you.

Could not checkBecause the code is the app, the deepest version of this check reads your project, which needs you to connect it. From just an address we check everything reachable from outside and tell you which questions we could not answer.

What has happened before

A real case, on the record.

Georgia Tech’s tracker of real security holes traced to AI-written code attributed 27 of its 74 confirmed cases to Claude Code, the largest share of any single tool. Read that carefully: it reflects how much code the tool writes, not a higher rate of mistakes per line, and the researchers behind it say the true total across every tool is five to ten times what they can trace. The useful conclusion is not that one tool is unsafe. It is that code written this fast, by any of them, is going out unchecked.
