The short answer
Choose vas if you want a cheaper, instant, self-serve scan you run yourself: a free first scan, then $19-39/month, with copy-paste fixes and first-party data behind the remediation advice.
Choose VibeEval if you want a security engineer to verify every finding (their zero-false-positive claim), an autonomous agent firing 310+ probes across multiple roles, or the option to escalate to a scoped manual pentest.
Where vas is stronger
Cheaper, and free to start
vas runs your first scan free and shows your score and issue counts, then $19/month (Go) or $39/month (Pro). VibeEval starts at $49/month after a 14-day trial. If you are a solo founder scanning one app, vas is lower cost to start and to keep running.
Instant and fully self-serve
vas is automated end to end: paste a URL, get results in minutes, apply the copy-paste fix, re-scan. VibeEval's model puts a security engineer in the loop to verify findings, which is a strength for confidence but not the fastest path to a result you act on yourself.
Published first-party data
vas publishes data from its own corpus — across 1,215 AI-built apps, 39% of those on Supabase had a data-exposure finding — so the remediation guidance comes from seeing the pattern at scale.
Where VibeEval wins
These are real. VibeEval is a serious product and on some axes it goes further than vas.
Human-verified findings. A security engineer confirms each finding before it reaches you, and VibeEval claims zero false positives. vas is fully automated, and automated scanners (vas included) do produce false positives.
Agent with 310+ probes, multi-role. VibeEval's autonomous agent tests across multiple roles and chains findings into exploit paths, with captured proof-of-concept on each.
Manual pentest option. VibeEval offers scoped manual pentests with signed reports (from $2,900) for teams that need compliance-grade assurance. vas does not offer manual pentesting.

Frequently asked
What is the difference between VibeEval and vas?
Both sign in and test access control on live AI-built apps, including Supabase row-level security, IDOR/BOLA and auth bypass. VibeEval runs an autonomous agent with 310+ probes and has a security engineer verify each finding before reporting, claiming zero false positives, from $49/month. vas is fully automated and instant, cheaper (free first scan, then $19-39/month), and publishes first-party scan data. Choose VibeEval for human-verified findings and an escalation path to a manual pentest; choose vas for a cheaper, self-serve scan you run yourself in minutes.
Does VibeEval do authenticated testing?
Yes. VibeEval's agent tests across multiple roles and can work past auth walls, and it explicitly targets Supabase RLS, Firebase rules, IDOR/BOLA and role escalation. vas also does authenticated testing with optional test credentials. On this axis the two are genuinely comparable, which is why the honest differences are price, verification model, and self-serve speed rather than capability alone.
How much does each cost?
VibeEval is $49/month (Pro), $149/month (Team), or $499 one-time (Lifetime), with a 14-day free trial and free single-purpose checkers. vas is free for your first scan, then $19/month (Go) or $39/month (Pro). vas is cheaper to start and to run monthly; VibeEval adds human verification and a separate manual pentest option starting at $2,900.
