Comparisons Vibe App Scanner
Vibe App Scanner alternative — URL scanning vs. reading the code
Vibe App Scanner is an external, black-box security scanner for vibe-coded apps. You paste a URL; it sends requests to the running site and reports what comes back — exposed keys in the served bundle, misconfigured headers, Supabase tables that answer with the anon key, email records, and a bundle of SEO, accessibility and performance checks alongside them. There is no repository connection anywhere in the product, by design: it never asks for GitHub access and never reads source. Its Pro tier goes a step further and logs in with a test account to probe authenticated pages.
Where Vibe App Scanner wins
There is one thing they do that we do not, and it is not a small thing: their Pro tier authenticates against your running app and tries to reach data it should not be able to reach. That is a real answer to a real question, and a static reading of your repository is not a substitute for it. They also cover ten backends to our one, and they need nothing from you but a URL — no GitHub App, no repository access, no install. If your app is not on Supabase, or you will not connect a repository, this page ends here and they are your answer.

Choose Vibe App Scanner if
- Your backend is Firebase, Convex, MongoDB, Bubble or Postgres — anything but Supabase.
- You will not connect a repository, and a URL is all you are willing to hand over.
- You want the running app probed with a logged-in test account, which is the one thing we do not do yet.
- You want SEO, accessibility and performance checked in the same pass as security.
- You do not have the source — you are checking somebody else's deployed app.
Choose Sentris if
- The bug is in a migration that has not shipped yet, so there is nothing live to scan.
- You want the route handler read, not inferred from a 200 response.
- You want monitoring on the $19 tier, not only on the $39 one.
- A fix-and-verify loop burns three to five scans per finding, and 20 scans a month is tight.
- You want the security checks counted honestly, without SEO and Lighthouse scores padding the number.
Questions
Does Vibe App Scanner read source code?
No. It is an external scanner and there is no repository connection anywhere in the product — no GitHub App, no OAuth, no file access. Their own description on TrustMRR calls it an "automated external security scanner", and neither their pricing page nor their check list mentions a code path. One third-party comparison table on dev.to lists them as reading source code; that table is wrong. It matters because the failure modes people complain about most in this category — an inverted auth check, a query with no ownership filter, an admin route guarded only in React — are invisible from the outside.
They advertise 150+ checks. Sentris has nine. Isn't that a landslide?
The two numbers count different things. Their own check list page says "Every check we run. All 33 of them." — the 150+ refers to secret patterns, which they state plainly on the same site. Of those 33 checks, nine are SEO, AEO, accessibility and performance rather than security, which leaves 24 security checks against our four rule checks plus five AI checks. That is still more than we run, and we would rather say so than pick a different number to count.
Is Sentris cheaper?
At the entry tier the price is identical — $19 either way — but the contents differ: their $19 is 20 scans a month across 3 projects with no monitoring, ours is one project with unlimited re-scans and weekly monitoring. Monitoring starts at $39 with them. Which is cheaper depends entirely on whether you want breadth or a watched target.
Should I run both?
If your app is on Supabase and you have the source, yes, and the reason is specific: they answer "does this running app accept requests it should not?" and we answer "does this code contain the mistake that would let it?". Those are two different questions and neither answer implies the other.
One number nobody else on this list publishes
False-positive floods are the standing complaint about this whole category, and not one tool in it states its rate. Ours is precision 1.000, recall 1.000 over 24 planted findings in 9 repositories — with the date, the commit, the scoring rules and the command that reproduces it, plus a paragraph on why 9 repositories is a small corpus. Measured 2026-08-11.
