Is my Replit app safe?
Using the app tells you nothing about this. A leaked key or an open database looks completely normal in the browser. The reliable answer comes from checking the live app, which is what this page does.

What it means
A password-like key that is supposed to stay private is sitting in your app where other people can find it. Anyone who copies it can act as you — run up bills, read your data, or send email in your name.
Why AI tools cause it
AI coding tools often paste an API key straight into a file to make something work, instead of hiding it in a private environment variable. It runs fine, so nothing warns you.
How xlogs checks it
xlogs scans your live JavaScript against 9 key formats covering Stripe, OpenAI, Anthropic, AWS, Google, GitHub, Slack, private key blocks, and Supabase service_role tokens.
The parts of a Replit app worth checking
First, the keys: none of your secret keys should be in the code the browser downloads. Second, the data: if your app uses a database, an anonymous request should not be able to read private rows. Third, the basics: security headers set, and no private files like .env served from the live site.
The scan below checks all of these and returns a plain-English fix for anything it finds.
How to fix it
The goal: The key is stored only in a server-side secret / environment variable, never in code or the client bundle, and the exposed value has been rotated (regenerated) because the old one is public.
- Move the key's value into a server-only environment variable
- Remove the literal value from the code and any client-side bundle (the affected spot)
- Make sure the .env file is in .gitignore
- Rotate (regenerate) the key at the provider — assume the old one is compromised
In my app (the spot the scan shows): a secret key is exposed. Please make this true: The key is stored only in a server-side secret / environment variable, never in code or the client bundle, and the exposed value has been rotated (regenerated) because the old one is public. Steps: Move the key's value into a server-only environment variable; Remove the literal value from the code and any client-side bundle (the spot the scan shows); Make sure the .env file is in .gitignore; Rotate (regenerate) the key at the provider — assume the old one is compromised. Then tell me exactly what you changed, and do not print any secret values back to me.
Then verify: After you deploy the fix, xlogs re-scans your live app and your files and confirms the key is no longer present.

Common questions
What is the most common Replit security mistake?
A secret key shipped in the frontend. It happens because pasting the key straight into the code is the fastest way to make a feature work. Anyone visiting the app can then copy it. The scan checks for this and tells you where the key was found.
