GuardMint vs vas
Two scanners for people launching AI-built apps. GuardMint runs a fast pre-launch checklist against your live app and, on Pro, scans your source code. vas can also sign in with test credentials and check the thing a checklist cannot: whether one logged-in user can actually read another user's data. Full comparison below, including where GuardMint wins.

The short answer
Choose vas if your real worry is whether one user can reach another user's data. vas signs into your app with test credentials and tries it, across up to 150 pages, which a pre-launch checklist does not do.
Choose GuardMint if you want the cheapest paid plan with source-code scanning included, you want daily (not weekly) monitoring, or you want a focused launch-blocker checklist for a solo project.
Where vas is stronger
One of these matters far more than the rest, so it goes first.
It signs in and tests the access rules
Give vas optional test credentials and it logs into your app and attempts to read records belonging to a different user, across up to 150 pages. GuardMint scans the live public surface and, on Pro, your source code, but neither runs a signed-in session that tries to break your access rules. An external or static scan cannot tell whether a logged-in user A can read user B's rows, because the endpoint returns 200 whether the policy holds or not.
Depth of crawl and coverage
vas crawls up to 150 pages and runs the full premium scanner set on a deep scan, including breach monitoring. GuardMint focuses on common launch-blocking risks, which it states plainly rather than claiming full coverage.
Where GuardMint wins
Cheaper paid plan with source scanning. GuardMint Pro is $19.99/month and includes GitHub source-code scanning. vas includes authenticated testing on Pro at $39/month; source-code scanning is not part of vas.
Daily monitoring. GuardMint Pro monitors daily. vas Pro monitoring runs weekly, so if you want a daily cadence, GuardMint offers it at a lower price.
Tight launch checklist. For a solo founder who just wants the launch-blockers (secrets, admin routes, headers, SSL, exposed files) before shipping, GuardMint's focus is a clean fit.

Frequently asked
What is the difference between GuardMint and vas?
GuardMint runs a pre-launch checklist against your live app (secrets, admin routes, headers, SSL, exposed files) and adds source-code scanning on its Pro tier. vas can also sign in with optional test credentials and check whether one logged-in user can read another user's data across up to 150 pages, which a checklist scan does not do.
How much does GuardMint cost?
GuardMint is free for on-demand scans of one project, and Pro is $19.99/month for up to 3 projects with copy-paste fix prompts, daily monitoring, and source-code scanning. vas is free for your first scan, then Go is $19/month and Pro is $39/month with weekly deep scans that include authenticated testing.
Which is better for catching Supabase data leaks?
Both flag exposed data and auth misconfiguration from the outside. vas goes further by signing in and testing whether your row-level-security policies actually scope each row to its owner, which is where the most common critical Supabase mistake hides and which an external checklist cannot confirm.
Test whether your access rules actually hold
Run your first vas scan free to see your security score and issue counts. Add test credentials on a paid plan and vas signs in to check whether one user can reach another's data.
