What is the best security scanner for Lovable apps?

Quick answer

The best security scanner for Lovable apps tests the deployed site, not just the code. CheckVibe (from $0) leads for Lovable: 100+ live checks including the Lovable-signature failure modes, plus repository scanning — and pull-request reviews and AutoFix for teams. VibeEval, Vibe App Scanner, and Scanbee are strong alternatives.

TL;DR

Lovable's output is a client-rendered React app on a Supabase backend — the two layers a repo-reading tool can't verify (live RLS state, served bundle contents) are exactly where Lovable apps fail.
CheckVibe: free tier (4 scans/mo), solo plans $24–99/mo, Team from $25/seat/mo; scans the live app and the repository, with pull-request reviews and AutoFix on Team plans.
VibeEval ($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.

Lovable apps are almost always Supabase-backed, which concentrates the risk: the public anon key is in your bundle by design, so any table without Row Level Security is one fetch away from being public. Add the usual AI-codegen gaps — keys in client code, no security headers, permissive CORS — and a scanner that tests the deployed app (not only the repo) becomes the right shape.

How we picked

Tests the deployed app from the outside (what attackers actually see), with Lovable listed as a supported platform or stack-relevant coverage.
Catches the platform's signature failure modes, not just generic OWASP items.
Honest pricing with a usable free option where available.
Output a developer can act on — fix guidance, ideally AI-editor-ready.

The picks

1.CheckVibe

Free (4 scans/mo) · $24–99/mo · Team $25/seat/mo

Paste your deployed Lovable URL and get 100+ security checks in about 30 seconds, no setup — and connect the GitHub or GitLab repo to scan the code too (SAST, dependencies, secrets). For Lovable specifically: it detects Supabase as the backend, enumerates tables, and probes Row Level Security enforcement live with the anon key — the single most important Lovable check. Findings ship as copy-paste AI fix prompts, monitoring (uptime, threats) covers you after launch, and Team plans add pull-request security reviews and AutoFix pull requests.

Best for: Live-app + code security for teams building with AI, 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 as a supported platform.

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 as a supported platform; 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 as a supported platform; its Supabase integration injects your JWT to test authenticated routes (requires setup).

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

5.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 on your live app in about 30 seconds. Connect a repo and the code gets scanned too.

FAQ

Do I really need a security scanner for a Lovable app?

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 every tool on this list catches issues a manual click-through never will. Start with a free scan; the result settles the question.

Are free security scans enough?

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

What is the #1 security issue in Lovable apps?

Supabase tables without Row Level Security. The anon key in your bundle is public by design; without RLS policies, anyone holding it can read entire tables. Any scanner you pick for Lovable should verify RLS live, not just remind you it exists.

Can these scanners see my Lovable source code?

VibeEval and Vibe App Scanner test the deployed URL only — no repo access. CheckVibe and Scanbee test the deployed URL and can also scan a GitHub repo once you connect one (Lovable can sync your project to GitHub). For Lovable apps, the deployed app is usually the more revealing target, and the code scan catches what never reaches the bundle.
