New: SEO & AEO scanning — see how Google ranks you and how ChatGPT, Claude & Perplexity cite youSee how it works
The best security scanner for Lovable apps tests the deployed site, not just the code. CheckVibe (from $0) leads for Lovable: 100+ checks including the Lovable-signature failure modes, plus SEO/AEO scanning no competitor offers. VibeEval, Vibe App Scanner, and Scanbee are strong security-only options.
TL;DR
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 the repo) becomes the right shape.
Paste your deployed Lovable URL and get 100+ security checks plus 68 SEO and 46 AEO checks in about 30 seconds — no repo access, no setup. 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, and monitoring (uptime, vitals, threats) covers you after launch.
Best for: All-in-one security + visibility, from $0
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
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
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
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.
Run a free CheckVibe scanIf 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.
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.
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.
CheckVibe, VibeEval, and Vibe App Scanner test the deployed URL only — no repo access. Scanbee can additionally scan a GitHub repo if you connect one. For Lovable apps, the deployed app is usually the more revealing target.
