CheckVibe vs Vibe App Scanner: which should you use?
Both scan vibe-coded apps for security issues from a URL. Vibe App Scanner sells one-time security audits ($9–19) and a $99/month continuous plan — security only. CheckVibe is a security platform for developer teams building with AI ($0 free, solo plans $24–99/month, Team Basic from $25 per seat/month (5-seat minimum)): the live-app scan plus repository scanning, uptime and threat monitoring, an API and an MCP server — and on Team plans, pull-request reviews and AutoFix.
TL;DR
- Vibe App Scanner: one-time security scans from $9, continuous protection $99/mo — no free scan tier listed as of June 2026.
- CheckVibe: free tier with 4 full scans/month; paid from $24/mo — continuous coverage starts well under their $99/mo tier, and Max ($99/mo) adds uptime, performance, and domain monitoring on top of security.
- Vibe App Scanner: no uptime monitoring, API, or MCP server mentioned on their site as of June 2026.
- CheckVibe adds 60-second uptime monitoring with public status pages, threat detection, per-scan regression diffs, REST API, and an MCP server.
- Both scan the live app from a URL and both check Supabase/Firebase database rules. CheckVibe can also scan a connected GitHub or GitLab repository (SAST, dependencies, secrets); Vibe App Scanner works from the URL only.
Vibe App Scanner (vibeappscanner.com) is one of the best-known security scanners for vibe-coded apps — it popularized the "89.5% of AI-built apps ship with vulnerabilities" framing and offers quick, affordable one-time audits. CheckVibe covers the same live-app ground on a subscription model, then extends it to the code (repository scanning, and pull-request reviews and AutoFix on Team plans) and to what a shipped app needs after launch: uptime, threat, and domain monitoring. Here is the factual comparison; Vibe App Scanner facts verified against their site on June 12, 2026.

FAQ
Is CheckVibe cheaper than Vibe App Scanner?
At the entry and middle tiers, yes: CheckVibe starts at $24/month against their $99/month Continuous Protection, and there is a free tier with 4 scans a month. CheckVibe Max is $99/month and adds uptime, performance, and domain monitoring alongside security. For a single one-time audit, Vibe App Scanner is cheaper ($9–19 one-time) — CheckVibe doesn't sell one-time scans.
Do both tools scan without repo access?
Yes. Both scan the deployed app from its URL, and neither requires connecting your repository for that. CheckVibe can additionally scan a connected GitHub or GitLab repository (SAST, dependencies, secrets) and, on Team plans, review every pull request through its GitHub App.
Which tool checks Supabase security?
Both do. Vibe App Scanner checks database access rules for Supabase and Firebase. CheckVibe probes Row Level Security live with your public anon key, enumerates exposed tables, audits storage buckets and edge function configuration, and tests any Firebase Realtime Database the page points at for world-readable rules.
Can I monitor my app continuously with both?
Vibe App Scanner's $99/month plan runs regular automated security re-scans with alerts and breach monitoring. CheckVibe's plans add scheduled security scans plus uptime checks every 60 seconds, Core Web Vitals tracking, and domain monitoring.
