New: SEO & AEO scanning — see how Google ranks you and how ChatGPT, Claude & Perplexity cite youSee how it works
They test different things. VibeCheck (runvibecheck.com) audits the source code of public GitHub repos with AI — a "Vibe Score" before you ship. CheckVibe tests the live deployed app from the outside: 100+ security checks plus SEO and AEO scanning. Many developers use a code audit pre-deploy and a live scan post-deploy.
TL;DR
This page compares CheckVibe with VibeCheck at runvibecheck.com (the AI code auditor for vibe-coded apps). Other products and open-source projects also use the "VibeCheck" name; they are not covered here.
VibeCheck (runvibecheck.com) answers "is this code okay?" — paste a public GitHub URL and an AI audit returns a Vibe Score with security and performance anti-patterns, dead code, and fix suggestions. CheckVibe answers "is this *app* okay?" — it probes the deployed site the way an attacker (or an AI crawler) actually encounters it. The two are more complementary than competitive. Facts verified against both sites on June 12, 2026.
| CheckVibe | VibeCheck | |
|---|---|---|
| What it tests | The live deployed app (URL-based, from the outside) | Source code of a public GitHub repository |
| Security coverage | 100+ live checks: Supabase RLS probing, exposed keys in served bundles, headers, SQLi/XSS probing, CORS, JWT, DNS/email | AI code review: security + performance anti-patterns, dead code, dependency analysis, AI-pattern recognition |
| Catches deploy-layer issues (headers, DNS, TLS, live RLS state) | Yes | No |
| Catches code-level issues before deploy | Partially (SAST on served JS; the app must be deployed) | Yes |
| SEO / AEO scanning | 68 SEO + 46 AEO checks | Not mentioned on their site as of June 2026 |
| Private repos | Not needed — no repo access at all | Public repos only; private/team "coming soon" as of June 2026 |
| Free tier | $0 — 1 project, 4 scans/month | $0 — 3 scans/month, basic Vibe Score |
| Pricing | Free $0 (4 scans/mo) · Starter $24/mo · Pro $39/mo · Max $59/mo (annual −30%) | Free $0 · Pro $19/mo (unlimited scans) · Pay-per-scan $5 |
| Monitoring | Uptime, threat detection, scheduled scans, regression alerts | Not mentioned on their site as of June 2026 |
The fastest way to decide: scan your app with both.
CheckVibe's first scan is free — security, SEO, and AEO in about 30 seconds.
Run a free CheckVibe scanNo. VibeCheck (runvibecheck.com) is an AI source-code auditor for public GitHub repos. CheckVibe is a live-app scanner that tests your deployed site without any repo access. They examine different layers of the same app.
No — it takes a public GitHub repository URL as input and audits the code. To test the deployed app itself (headers, live database exposure, TLS, crawlability), you need a URL-based scanner like CheckVibe.
It's a reasonable workflow: a code audit pre-deploy catches anti-patterns early, and a live scan post-deploy verifies what actually shipped — including configuration that never appears in the repo, like your production headers or whether RLS is enabled on the real database.
