Supahound vs Vibe App Scanner: outside-in tests vs inside-the-logs detection
Vibe App Scanner (VAS) is an external scanner for AI-built apps: it tests a live URL and reviews source code from GitHub. Supahound reads your Supabase edge logs and alerts on abnormal traffic per user. VAS attacks your app to find holes; Supahound watches real users to see who goes through them.

| Question | Supahound | Vibe App Scanner |
|---|---|---|
| Tests the live app from outside? | No. It reads your logs. | Yes. Database, auth and APIs, including missing RLS. |
| Reviews source code? | No. | Yes. From GitHub or a ZIP upload. |
| Watches live Supabase traffic? | Yes. Edge logs every 1–2 minutes on paid plans. | No. It does not read Supabase logs. |
| Per-user detection? | Yes. Detectors run per actor. | Not described. |
| How often does it check? | Every 1–2 minutes on paid plans. | On demand; weekly monitoring on Pro. |
| Price for one project | $29 per month (Builder). | First scan free; Go $29 per month; Pro $49 per month. |
What does Vibe App Scanner do well?
- Tests the deployed app's database, auth and APIs from outside, including missing Supabase RLS and Firebase rules.
- Separate source-code review from GitHub or a ZIP upload.
- Pro deep scans can log in and test authenticated access.
- A remote MCP server lets Cursor, Claude Code or Windsurf start scans and pull reports (Pro or an eligible AppSumo plan).
What does Vibe App Scanner not cover?
- Scans run from outside, on demand or weekly. VAS does not read Supabase logs, so it cannot see who reads data in production.
- No per-actor detection of cross-tenant reads, credential stuffing or scraping is described.
- Monitoring is weekly on Pro. Go has no automated monitoring.
How much does Vibe App Scanner cost?
Free covers your first live-app scan, with one finding revealed. Go is $29 per month for 20 live-app scans and 10 repository scans per month, up to 3 projects, with no automated monitoring. Pro is $49 per month for 150 live-app and 50 repository scans per month, weekly extended scans, weekly monitoring with alerts, breach and email checks, and up to 10 projects. These prices are for new accounts; an AppSumo lifetime deal also exists. Supahound's posture scan is free; runtime detection is $29 per project per month (pricing).
Which one should I choose?
Choose Vibe App Scanner if you build on any stack (Supabase, Firebase and others) and want an outside-in test of the live app and a code review in one cheap plan.
Choose Supahound if your app runs on Supabase and you need to know within minutes when a real user or a leaked key starts doing something abnormal.
Frequently asked questions
- Does Vibe App Scanner monitor my app continuously?
- Pro includes weekly monitoring with alerts. Go has no automated monitoring. Neither plan reads Supabase logs, so VAS cannot see what real users do between scans.
- Can VAS find a missing RLS policy?
- Yes. It tests the deployed app's database from outside, including missing Supabase RLS. Supahound's free posture scan also reports RLS coverage, then its paid detectors watch whether anyone exploits a gap.
- Does Supahound work for Firebase apps?
- No. Supahound reads Supabase edge logs only. If you run Firebase, VAS covers it and Supahound does not.
