Best Vibe Coding Security Tools (2026)

Quick answer

The best vibe coding security tools scan the deployed app, not just the code. CheckVibe (from $0) leads on breadth: 100+ security checks plus SEO and AEO. VibeEval goes deepest on agent-based testing, Vibe App Scanner is the cheapest one-off audit, and OWASP ZAP is the free manual standard.

TL;DR

Vibe-coded apps fail in the deployed artifact, not the repo — keys baked into the served bundle, database tables without access rules, missing security headers. Pick a tool that tests the live URL.
CheckVibe: free tier (4 scans/mo), $24–59/mo paid; the only tool here that also scans SEO and AEO in the same pass.
VibeEval (free surface scan, $19/mo, $199 lifetime) goes deepest on autonomous agent-based security testing; Vibe App Scanner ($9–19 one-time) is the cheapest single pre-launch audit.
Scanbee's free tier is the widest free coverage — DAST, SAST, SCA and AWS cloud posture — but its paid tiers are still listed "Coming Soon".

AI writes code that runs before it writes code that is safe. Whatever generated it — a prompt-to-app builder, an agentic editor, a chat window — the gaps repeat: an API key that made it into the browser bundle, a database left readable by anyone holding the public key, no security headers, CORS opened to everything, error pages that narrate the stack. None of that is visible from a quick click-through, and much of it is invisible in the source too: it only exists in what actually got deployed. So the useful question is not "which scanner has the most rules" but "which tool tests the thing attackers can reach". This list is ordered by how much ground each tool covers for a solo developer, with pricing stated as the vendors state it.

How we picked

Tests the deployed app from the outside — served bundle, live headers, real backend access rules — not only the source.
Catches the failure modes AI code generators actually produce, not just a generic OWASP checklist.
Honest, public pricing with a usable free option where one exists.
Output a vibe coder can act on — fix guidance, ideally AI-editor-ready.

The picks

1.CheckVibe

Free (4 scans/mo) · $24–99/mo

Paste your deployed vibe-coded app URL and get 100+ security checks plus 68 SEO and 46 AEO checks in about 30 seconds — no repo access, no setup. Across builders it covers the recurring vibe-coding failure modes: API keys exposed in the served bundle, live Supabase Row Level Security probing, missing security headers, and permissive CORS. Findings ship as copy-paste AI fix prompts, and monitoring (uptime, vitals, threats) covers you after launch.

Best for: All-in-one security + visibility, from $0

2.VibeEval

Free surface scan · $19/mo · $199 lifetime

Autonomous browser-agent security testing of the live app — including behind auth walls and CAPTCHAs (their claim). Security-only. Lists Lovable, Bolt.new, Cursor, v0, Replit and Windsurf as supported platforms.

Best for: Deep agent-based security testing

3.Vibe App Scanner

$9–19 one-time · $99/mo continuous

One-time security audits of the deployed app: exposed secrets, database access rules (Supabase/Firebase), headers, auth. No free scan tier listed as of June 2026. Lists Lovable, Bolt.new, Cursor, v0, Replit and Windsurf as supported platforms; checks Supabase access rules.

Best for: A cheap one-off pre-launch security audit

4.Scanbee

Free (3 targets, 20 scans/mo) · paid tiers listed "Coming Soon"

Five security scanner types — DAST, SAST, SCA, CSPM (AWS), vulnerability assessment — accepting both URLs and GitHub repos, with a native Supabase integration. Lists Lovable, Bolt, Cursor, Claude Code, v0 and Replit as supported platforms; its Supabase integration injects your JWT to test authenticated routes (requires setup).

Best for: Source + live + cloud security in one product

5.VibeWrench

Free (3 scans/mo) · $9–19/mo

Eighteen tools in one cheap subscription — a 9-area security scan, basic SEO scan, Lighthouse speed, and utility generators. Lighter per category. Covers Bolt.new on its homepage; its security guides cover Windsurf.

Best for: Budget multi-tool quick checks

6.OWASP ZAP

Free, open source

The open-source standard for dynamic web app security testing. Extremely capable, entirely manual: you run it, configure it, and interpret the results. No vibe-coding-specific checks (no Supabase RLS probing, no AI-pattern detection).

Best for: Hands-on testing without a SaaS

Start with the free scan.

100+ security checks, 68 SEO checks, 46 AEO checks. One URL, about 30 seconds.

FAQ

Do I need a security scanner if I code with AI?

If the app has users, data, or payments — yes. AI-generated apps ship with a consistent set of gaps (exposed keys, missing access control, no headers), and the model that wrote them has no view of what actually got deployed. A free scan settles the question in about the time it takes to read this answer.

What should a vibe coding security tool check?

Four things at minimum: secrets in the served bundle (the signature AI-codegen leak), backend access rules enforced live rather than assumed — Supabase Row Level Security being the common case — security headers and CORS on the real responses, and the classic injection and error-disclosure battery. Anything that only reads source code cannot verify the first three.

Are free scans enough?

A free scan is enough to find out where you stand today, and every tool here except Vibe App Scanner has one. Paid tiers buy continuity (scheduled scans, monitoring, alerts) and depth (more pages crawled, more checks). For a side project, a free-tier scan before each launch may genuinely suffice.

Can my AI editor just review its own code for security?

Asking it to security-review a diff genuinely helps, but it sees code, not the deployed reality — live headers, TLS, DNS, actual access-rule enforcement, what's really in the served bundle. External scanning verifies the thing users and attackers touch, then hands the findings back as fix prompts the editor can execute.
