Vibe-coding security scanners, compared honestly (2026)
There are now half a dozen tools that will “security scan your vibe-coded app.” They are not interchangeable, and the differences are not the ones the landing pages emphasize. Most of them read your code or your page markup. Very few touch the app you actually deployed, and, as critics of this category keep pointing out, almost none execute real authenticated requests, which is the only way to detect the failure that actually leaks user data: one signed-in user reaching another's records. Here is who does what, including what each tool does better than we do.
| Tool | Code & dependencies | Tests the deployed app | Signs in & tests cross-user access (BOLA) |
|---|---|---|---|
| CheckVibe | Connected Supabase audit on paid plans, not general code review | Scans the deployed site; findings ranked by what to fix first | Its auth prober re-tries login-gated pages logged out; nothing signs in as two users |
| Vibe App Scanner | AI review of the app; exact depth varies | URL-based check of the app surface | No public claim of signed-in cross-user testing, as of Sep 2026 |
| VibeCheck (notelon.ai) | AI scan with graded findings | URL-based check of the app surface | No public claim of signed-in cross-user testing, as of Sep 2026 |
| amihackable.dev | Not its job | Quick free exposure check of a public URL | Surface check only; nothing signs in |
| Aikido (free tier) | The real depth here: code, dependencies, secrets, cloud config | Primarily code-side; web scanning is unauthenticated | No signed-in cross-user testing of your app |
| Lovable built-in review | Reviews the code it generated, including the Supabase setup | A review of the project, not an outside test of the deployed app | And it is the builder grading its own work |
| ArgosX | Honestly: we do not do code or dependency review. Aikido is better there | Tests the deployed app from the outside, free, no signup | Pro signs in as two of your test accounts and proves cross-user access (BOLA) with the exact request and response |
CheckVibe details read live from checkvibe.dev on 2026-09-10. Other tools are described at category level from their public pages as of September 2026; no competitor dollar figures here because they go stale, so check their current pages. Our own plans are on pricing.
The tools, one by one
CheckVibe
Scans the deployed site and, on paid plans, a connected Supabase backend. Covers security plus SEO and AEO, with findings ranked by what to fix first.
Pricing shape: Permanent free tier (not a trial), then subscriptions; the top tier adds white-label reports licensed for handing to clients.
Where it wins: Breadth beyond security (SEO/AEO in the same report) and the team/agency features: report licensing and per-client portals. If you want one tool for security plus search health, this is the strongest option here.
Vibe App Scanner
A quick AI security scan aimed at vibe-coded apps, run against your app.
Pricing shape: Free entry point; paid options. Shape may have changed since September 2026.
Where it wins: Low friction for a first look.
VibeCheck (notelon.ai)
An AI scan that grades a vibe-coded app and lists findings.
Pricing shape: Free entry point, as of September 2026.
Where it wins: A fast, simple read on where you stand.
amihackable.dev
A free instant check of what a public URL exposes.
Pricing shape: Free.
Where it wins: Zero-commitment first check; takes seconds.
Aikido Security (free tier)
A developer security platform: static code analysis, dependency and secret scanning, cloud configuration checks.
Pricing shape: Genuinely useful free tier for small teams; subscriptions above it.
Where it wins: Code and dependency depth. Nothing else on this page reads your repo the way Aikido does. If your risk is a vulnerable package or a bad commit, start here.
Lovable built-in security review
A security review that runs inside Lovable against the app it built for you.
Pricing shape: Included with Lovable.
Where it wins: Zero friction if you build on Lovable: no setup, no second tool, and it knows your Supabase wiring. Run it. Then get an outside opinion too.
ArgosX
Independent runtime testing of the app you deployed. The free scan checks the public surface (database exposure, secrets served to the browser, headers). Pro signs in with test accounts you provide and tests cross-user access, with a human-verified option.
Pricing shape: Free scan with no signup; paid plans on the pricing page.
Where it wins: The one thing no other tool on this page does: authenticated cross-user testing of the live app, with the request and response as proof.
Why that one column matters
The breach pattern that actually hits vibe-coded apps is not exotic: it is user A reading user B's data, because the database policy or the API check that should separate them was never finished. A code linter can guess at it. A logged-out re-try of a gated page cannot see it at all, because the bug only exists between two logged-in sessions. The only test that settles it is signing in as two real users and making the request. That is what an ArgosX Pro scan does, with your permission, using test accounts you provide, and the finding comes with the exact request and response so you can watch it happen.
Our own limits, stated plainly: the free ArgosX scan is public-surface only and never logs in. Authenticated testing requires your explicit permission. A deep scan takes tens of minutes, not seconds, because we drive the app rather than read its markup. And we do not review your source code or dependencies; if that is your main risk, pair us with a code-side tool like Aikido rather than replacing it.
Start with the free scan.
Your deployed URL, a couple of minutes, no signup. It checks the public surface: database exposure, secrets served to the browser, headers.
