SharkVoid vs vas
This is the closest comparison of the bunch, because both tools sign in and test access control rather than only scanning the public surface. The real difference is shape: SharkVoid is broad and cheap, adding SAST, git-history secret scanning, mobile app scanning and a runtime protection agent. vas is narrower and deeper, focused on a deployed app's access rules and Supabase row-level security. Full comparison below, including where SharkVoid wins.

The short answer
Choose vas if your specific worry is data exposure through broken access control. vas specializes in Supabase and Firebase row-level security, signs in to test whether one user can read another's rows, and comes from the team that published a study of that exact failure mode across 1,215 apps.
Choose SharkVoid if you want the widest coverage for the least money: source-code (SAST) scanning, secrets in git history, mobile app scanning, and a runtime RASP agent that blocks attacks in production, starting at $2.99 per scan.
Where vas is stronger
Depth on access control, not breadth across everything
vas concentrates its whole scanner suite on the failure mode that actually leaks data in AI-built apps: row-level-security policies that are missing, disabled, or written as "allow any authenticated user" instead of "allow the row's owner." It signs in, tests cross-user reads across up to 150 pages, and checks Supabase and Firebase configurations specifically. A broad generalist covers more ground; vas is tuned for the one category that most often exposes real records.
Published data on the exact problem
vas publishes first-party data from its own corpus: across 1,215 AI-built apps, 39% of those on Supabase had a row-level-security or data-exposure finding. The remediation guidance is built from seeing that pattern at scale, not from generic rules.
Free first scan of the full suite
vas runs its full check suite on your first scan for free and shows your score and issue counts. SharkVoid's free tier is 3 scans a month limited to public repos and unauthenticated web scanning.
Where SharkVoid wins
These are real and they matter. SharkVoid is the broader product.
Source code and mobile coverage. SharkVoid runs SAST over your repo, scans git history for committed secrets, and scans mobile apps (APK/IPA). vas does none of these; it reads the deployed app.
Runtime protection (RASP). SharkVoid ships an npm agent that blocks attacks in production. vas is a scanner, not a runtime shield, so it has no equivalent.
Lower entry price. SharkVoid starts at $2.99 per scan with no subscription, and Starter is $14.99/month for 20 scans. If price is the deciding factor, SharkVoid is cheaper to start.

Frequently asked
What is the difference between SharkVoid and vas?
SharkVoid is broad: it runs SAST and DAST against a website, GitHub repo, or mobile app, scans git history for secrets, and ships a runtime RASP agent that blocks attacks in production. vas is narrower and deeper: it focuses on a deployed app's access rules, especially Supabase and Firebase row-level security, and signs in with test credentials to check whether one user can read another's data. If you want the widest coverage for the lowest price, SharkVoid is strong. If your specific worry is data exposure through broken access control, vas specializes in it.
Does SharkVoid do authenticated testing?
Yes. SharkVoid's multi-agent scan includes an authenticated access-control agent, though authenticated web scanning is a paid-tier feature (its Pay As You Go tier is unauthenticated web scanning only). vas also does authenticated testing with optional test credentials; its focus is specifically on row-level-security overexposure, where a policy lets any logged-in user read every user's rows.
How much does SharkVoid cost?
SharkVoid is free for 3 scans a month (public repos, unauthenticated web), $2.99 per scan pay-as-you-go, $14.99/month for the Starter plan (20 scans, private repos, agent), and $39/month for Pro (unlimited scans, RASP agent, 24/7 monitoring). vas is free for your first scan, then Go is $19/month and Pro is $39/month.
Go deep on your app's access rules
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.
