Buyer's Guide

Best Vibe Coding Security Scanners (2026)

If you built your app with Lovable, Bolt, Cursor, Replit or v0, a security scanner catches the exposed keys and missing database rules those tools tend to ship. Here's an honest, side-by-side look at the main options — including where they beat us.

Vibe App Scanner Deployed-URL scan

Scans: Deployed URL · Best for: A fast pre-launch check without touching code · Price: Per-scan

Vibe App Scanner runs against your live URL, auto-detects your stack, and probes for exposed secrets, missing security headers, auth issues and database misconfigurations that Lovable, Bolt, Cursor and Replit tend to introduce. A solid choice if you only want to test the deployed app and don't need code-level scanning or an IDE workflow.

  • No source code required
  • Auto-detects your tech stack
  • Fast results
  • No source-code or IDE scanning
  • Deep scans are paid per-run
CheckVibe Free URL scan

Scans: Deployed URL · Best for: A free first look at a live site · Price: Free tier

CheckVibe scans a deployed URL against a large set of checks in parallel — exposed keys, injection, XSS and more — with no install or config. Good as a free starting point, though like other URL-only tools it can't see your source code or run inside your editor.

  • Free to start
  • Many checks, no setup
  • URL-only — no code scanning
  • Output leans technical
Snyk Enterprise / dev teams

Scans: Code, dependencies, containers · Best for: Engineering teams with CI/CD · Price: Free for OSS, paid per seat

Snyk is the industry standard for software composition analysis and has an unmatched vulnerability database. If you have a developer and a real pipeline, it's excellent. For a solo non-technical founder, the output — CVE IDs, CVSS scores, dependency trees — is hard to act on, and it won't know what Supabase RLS is.

  • Best-in-class dependency/CVE coverage
  • Deep CI/CD and container scanning
  • Requires a developer to set up and read
  • No vibe-coding-specific checks
Semgrep Developer SAST

Scans: Code (SAST), dependencies, secrets · Best for: Developers who want customisable rules · Price: Free tier, paid teams

Semgrep is a powerful, developer-focused static-analysis tool with AI-assisted rules to cut false positives. Great if you write code and want fine-grained control. Like Snyk, it assumes a developer audience rather than a founder who needs to know "is my app safe to launch?"

  • Strong, customisable SAST
  • Generous free tier
  • Built for developers, not founders
  • No deployed-URL scanning
AuditYourApp Supabase / Firebase

Scans: Supabase & Firebase config, URL · Best for: Database-specific checks · Price: Limited free, paid

AuditYourApp focuses on the backend layer where vibe-coded apps most often leak: exposed RLS rules, unprotected RPCs and leaked API keys in Supabase and Firebase. A good complement if your main worry is database access control specifically.

  • Deep Supabase/Firebase focus
  • Catches exposed RLS and RPCs
  • Narrower scope than a full scanner
  • No IDE or CI/CD workflow

How to choose

Start with what you can give the scanner. If you only have a deployed URL and no code, a URL scanner (VibeSafe, Vibe App Scanner, CheckVibe) is your path. If you have the source, code-aware tools (VibeSafe, Snyk, Semgrep) go deeper.

Then match it to who's reading the report. If a developer will act on the findings, Snyk or Semgrep give the most depth. If you — a founder — need to understand and fix things yourself, pick a tool that explains issues in plain English and covers both code and the live app.

Don't over-buy. Most solo founders launching an AI-built app need three things covered well: no exposed secrets, Supabase RLS actually enabled, and no obvious auth holes. Any tool above handles the basics — the difference is how much interpretation it asks of you.

Our honest take

We build VibeSafe, so treat this with appropriate salt — but we wrote this guide to be genuinely useful even if you pick someone else. Snyk and Semgrep are outstanding if you're an engineering team. URL-only scanners are great for a fast pre-launch check. We built VibeSafe for the middle: the founder who has the code and the deployed app, isn't a security engineer, and wants one tool that checks both and tells them plainly what to fix.
