Common questions

Is Replit Agent code less secure?

AI coding tools generate from training data that includes insecure patterns. Replit Agent doesn't enforce security — it builds what you ask for. The scanner catches what gets missed.

Does scanning my Replit app cost anything?

No. First scan is free with no account. Sign up for 3 scans/day plus AI fix prompts.

Can I scan my Replit deployment URL?

Yes. Paste your `*.replit.app` URL and the scanner checks headers, secrets, injection vectors, and more.

Can I scan before deploying?

Yes. Use Code mode to paste code directly from Replit's editor.

What if my API key is exposed?

Secrets are auto-redacted. Raw keys replaced with [REDACTED] in stored results.
