Skip it if

Skip Prbl if you have no AI-generated code in production, or if you require a CLI, API, or CI/CD integration that Prbl doesn't yet offer.

The 30-second take
Biggest gripe

Going past 10 scans per month on Free requires Pro at $29/month, which may be a jump for light users.

Price reality

Prbl's free tier is the best way to sample—10 scans/month no credit card. Pro at $29/month suits individual developers and small teams. Team at $99/month is competitive for 10 members, cheaper than many SAST tools. Enterprise at $500+/month is for larger teams needing SSO. Compared to Snyk's free tier and paid plans, Prbl focuses on AI-specific issues, so it's cheaper if that's your only need, but doesn't replace full dependency scanning.

In short

Prbl — Security scanner that finds AI-generated vulnerabilities and fixes them with verified, minimized diff. Best for Development teams using Cursor, Copilot, or other AI code generators, Vibe coders building production apps with AI tools, SaaS startups preparing for SOC 2 audits. Free to start; paid plans from $29/mo.

About Prbl

FreemiumIntermediateNo APIWeb

Prbl is a security scanner built for teams shipping AI-generated code. It identifies which lines were written by AI tools like Cursor, Copilot, Bolt, Lovable, and Claude, then runs targeted checks on those lines—the seams where AI code meets human logic. It detects missing access control on AI-scaffolded routes, fallback secrets in environment variable lookups, timing-unsafe webhook signature checks, hardcoded credentials, SQL injection, and more. You paste a live app URL or public repo and get file-level findings in about 60 seconds, free, no account needed. What sets Prbl apart is its fix-verify loop: after a finding, the AI rewriter applies a minimal fix, captures a behavioral baseline first to prove the app still works, then re-scans to confirm the issue is gone. You review a clean diff before anything merges. It integrates with CodeQL and pip-audit, and scanner rules are open-source and auditable. Prbl is designed to run alongside—not replace—general-purpose scanners like Snyk or Semgrep, filling the specific gap of AI-introduced vulnerabilities. It's for developers, vibe coders, and startups preparing for SOC 2 audits. Pricing starts at $0/mo for 10 scans, Pro at $29/mo, Team at $99/mo, and Enterprise from $500/mo.

Behind the Verdict

Prbl tackles a real problem: AI coding tools can produce functional code with security blind spots that general scanners may miss. Its spotlight on seams—where AI code meets human code—is sharper than a blanket scan. The free tier is generous: 10 scans/month, no credit card, and you get the same detection as paid. The AI rewriter with baseline validation is its standout feature; it doesn't just hand you a patch, it proves the patch doesn't break anything. That's a trust builder. Weaknesses: no CLI, API, or IDE plugin yet, so it can't easily fit into continuous integration or local workflows. It scans via URL only, which may not suit private repos that aren't public. Also, it's narrowly focused on AI-generated code—if your team writes mostly human code, value is limited. For startups preparing SOC 2, it's a handy supplemental evidence source. For enterprises with existing SAST, it runs beside them as a niche layer. For teams without AI-generated code, skip it. Overall, if you use AI tools in production, Prbl is worth trying, especially the free scan. If your codebase is human-written, traditional SAST is still the mainstay.

Real-world workflow fit

Concrete scenarios for the personas Prbl actually fits — and what changes day-one when you adopt it.

Solo developer using Cursor

After generating a CRUD app with Cursor, you paste your public GitHub repo URL into Prbl's free scan.

Outcome: Within 60 seconds, you get a list of findings like a missing auth check on a delete route. You approve the AI rewriter's minimal fix, which passes your baseline tests, and re-scan shows zero vulnerabilities—ready to merge.

Startup CTO preparing for SOC 2

Before an audit, you run Prbl on your production app URL and public repos to document AI-introduced vulnerabilities.

Outcome: You generate a report showing fixed findings and a clean re-scan, serving as evidence that AI code seams were audited—strengthening your compliance posture.

Vibe coder shipping a Bolt-built MVP

Your app is built with Bolt and you're about to deploy. You use Prbl's free scan on the app URL to check for AI-left secrets or injection.

Outcome: You discover a hardcoded credential in a route file and use the Pro rewriter to fix it, verified by a behavioral baseline, so you deploy confidently without breaking features.

Use Cases

  • Scan any public GitHub repo for AI-generated vulnerabilities in under 60 seconds for free.
  • Identify missing authentication on AI-scaffolded CRUD routes before production deployment.
  • Detect fallback secrets (e.g., JWT_SECRET || 'default_secret') in environment variable lookups.
  • Prepare for SOC 2 audits by auditing AI-generated code for common security gaps.
  • Validate that automated fixes preserve baseline behavior before merging.

Models Under the Hood

Limitations

  • Prbl scans via pasted app URL or public repo URL only, with no mention of CLI, API, or IDE integration, which limits automation.
  • The free tier provides a quick scan without account creation, while the fix and baseline verification features are part of the Pro product.
  • It targets AI-generated code vulnerabilities, complementing other scanners.
  • The platform is web-based and no API is documented.

$500/mo starting

Ideal for

Larger organizations requiring unlimited members, SSO, audit logs, and high-volume scanning and rewriter capacity.

What this tier adds

Adds unlimited team members, SSO & audit logs, 1,000+ rewriter credits/month, and dedicated support vs. Team's 10-member cap.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • Going past 10 scans per month on Free requires Pro at $29/month, which may be a jump for light users.
  • Rewriter credits are capped (50/month on Pro), and using them up means paying for Pro upgrades or waiting a month.
  • Enterprise pricing starts at $500/month with unlimited members, but you may pay more for custom add-ons like SSO configuration.
  • Annual billing gives 2 months free, so monthly billing carries an implicit 16.7% premium.
  • Scanning private repos requires Pro or higher; Free is limited to public repos and URLs.

Where the pricing makes sense

The company stage and team size where Prbl's pricing actually pencils out — and where peers do it cheaper.

Prbl's free tier is the best way to sample—10 scans/month no credit card. Pro at $29/month suits individual developers and small teams. Team at $99/month is competitive for 10 members, cheaper than many SAST tools. Enterprise at $500+/month is for larger teams needing SSO. Compared to Snyk's free tier and paid plans, Prbl focuses on AI-specific issues, so it's cheaper if that's your only need, but doesn't replace full dependency scanning.

Setup time & first value

Migrating out
  • To Snyk or Semgrep: If you need broad dependency scanning and CI integration, Prbl's niche focus may not suffice—adopt a general-purpose SAST tool.
