Prbl: Pricing, Features & Best Use Cases

Security scanner for AI-generated code that finds issues, applies AI fixes, and checks them against a behavioral baseline.

Prbl homepage screenshot, coding AI tool

Our take: Use Prbl to scan an AI-built app or public repo for the flaws coding assistants commonly leave, free and without an account, and upgrade to Pro for AI-applied fixes you approve as a diff.

Main limitation: The free plan is limited to 10 scans a month and 3 repos, and the AI rewriter requires Pro with a monthly credit limit.

By the AI Tool Atlas editors. Based on the vendor's official documentation; we have not tested this product hands-on. What “documented overview” means

Who Prbl fits

Use Prbl to scan an AI-built app or public repo for the flaws coding assistants commonly leave, free and without an account, and upgrade to Pro for AI-applied fixes you approve as a diff. Based on the vendor's documentation, not on a hands-on test.

Best for: Vibe coders and indie developers

Also a good fit for

  • Small teams shipping AI-written code

Consider another tool if free plan limited to 10 scans per month and 3 repos

Or if

  • AI rewriter requires Pro
  • Rewriter limited by monthly credits

What is Prbl, and how does it work?

Prbl scans a live app URL or public repo for flaws AI coding tools commonly introduce, such as hardcoded keys, missing auth and injection. Its rewriter proposes fixes as a diff for approval. A free tier needs no account; paid plans add the rewriter, a GitHub Action and team features.
