Best vibe coding security tools
No single tool covers a vibe-coded app. The bugs AI coding tools ship most often, such as open database tables, keys in the frontend bundle and admin routes without server checks, show up on the deployed app, not always in the source. Pick one tool per row below: a live-app scanner, a database check, a code scanner, secret scanning and dependency alerts.
Vibe coding security tools compared
| Tool | Category | What it catches | Needs source code | Free option |
|---|---|---|---|---|
| VibeEval | Live-app scanner for AI-built apps | Exposed keys, open Supabase/Firebase data, missing auth, headers | No | Free surface scan |
| Supabase Security Advisor | Database lint | Tables with RLS disabled, risky function settings | No (dashboard) | Yes |
| Semgrep | SAST | Injection, unsafe patterns in code | Yes | Community edition |
| Snyk | SCA and SAST | Vulnerable dependencies, code issues | Yes | Free tier |
| GitHub secret scanning | Secrets | Keys committed to the repository | Yes | Free on public repos |
| Gitleaks | Secrets | Keys in git history, run locally or in CI | Yes | Open source |
| Dependabot | Dependency alerts | Known-vulnerable packages | Yes | Free on GitHub |
| OWASP ZAP | DAST | Generic web vulnerabilities on a running app | No | Open source |
Live-app scanners
A live-app scanner tests the URL your users visit. That is where a Lovable or Bolt app’s real configuration lives: which keys the bundle ships, which tables the public key can read, which routes answer without a session.
VibeEval’s free tools each check one surface: the token leak checker, security headers checker, env exposure checker and source map checker. The vibe code scanner runs them together, and the paid deep scan signs in as test users to check access between roles.
OWASP ZAP is the general-purpose option. It finds classic web issues but does not know Supabase or Firebase access rules.
Database checks
Most data exposure in vibe-coded apps is a database access rule, not a code bug. If you use Supabase, open Advisors → Security Advisor in the dashboard and fix every RLS warning. The Supabase RLS checker tests the same tables from outside with your app’s public key. For Firebase, the Firebase scanner checks for open Firestore and Realtime Database rules.
Code scanning (SAST)
If you have the code in a repository, a SAST tool reads it for unsafe patterns. Semgrep runs from the command line or CI with community rules. Snyk Code does the same with a hosted dashboard. Both miss configuration that lives outside the repository, such as RLS policies set in a dashboard.
Secrets and dependencies
Turn on GitHub secret scanning and push protection for the repository, and add Gitleaks to CI if you commit from several machines. Dependabot or Snyk Open Source alert you when a package you use gets a published vulnerability.
Which tools should I start with?
| Your setup | Start with |
|---|---|
| Lovable or Bolt app, no local code | VibeEval scan, Supabase Security Advisor |
| Cursor or Claude Code project in GitHub | VibeEval scan, Semgrep, secret scanning, Dependabot |
| App with paying customers or regulated data | All of the above, plus a pentest |
The AI security testing tools guide covers tools for testing LLM features such as prompt injection.
