New: SEO & AEO scanning — see how Google ranks you and how ChatGPT, Claude & Perplexity cite youSee how it works
CheckVibe is the only scanner that audits security (100+ checks including live Supabase RLS probing), SEO (68 checks), and AEO (46 checks with a 7-engine AI readiness matrix) in one URL-based scan — from $0. The alternative is assembling 3 tools: a security scanner, an SEO auditor, and an AI-visibility tracker.
TL;DR
Shipped apps fail in three independent ways: they get hacked (security), they don't get found (SEO), and — new since AI answers took over discovery — they're invisible to the engines people actually ask (AEO). Tools historically covered one lane each. This page answers the obvious question honestly: can one scanner cover all three well, and what does the assembled-stack alternative actually cost?
One URL in, three audits out. Security: 100+ checks including live Supabase RLS probing, exposed keys, SQLi/XSS, headers, JWT, dependencies. SEO: 68 checks including structured-data depth, canonicals, and CrUX field Core Web Vitals. AEO: 46 checks including AI-crawler access, llms.txt, machine readability, and a per-engine readiness matrix across 7 AI engines. Then monitoring keeps watch: uptime every 60s, vitals regressions, threat detection, email deliverability.
Best for: Everything in one scan, from $0
OWASP ZAP (free, manual) for security plus Google Search Console and Lighthouse (free) for SEO basics. Costs nothing but your time, requires security expertise to operate, and covers zero AEO — no AI-crawler testing, no llms.txt validation, no readability scoring.
Best for: Maximum frugality, hands-on operators
VibeEval ($19/mo) or Vibe App Scanner ($99/mo continuous) for security, Semrush/Ahrefs-class tooling for SEO ($99+/mo), Otterly ($29/mo) for AI-mention tracking. Three dashboards, three bills — and note the AEO lane is mention tracking, not readability testing: nothing in this stack verifies AI engines can parse your site.
Best for: Teams that want best-of-breed depth per lane
Start with the free scan.
100+ security checks, 68 SEO checks, 46 AEO checks — one URL, about 30 seconds.
Run a free CheckVibe scanLane by lane, honestly: on security, VibeEval's autonomous agent goes deeper behind auth walls than CheckVibe; on classic SEO, Semrush's keyword/backlink data has no equal in any scanner. CheckVibe's depth claim is the integration: one crawl feeds all three audits, findings share one dashboard and one fix-prompt format, and the AEO lane — readability testing — doesn't exist in the dedicated stacks at all.
Because they share root causes. The client-only rendering that hides your content from AI crawlers is an architecture issue; the missing security headers and the missing llms.txt live in the same config files; response-time problems hurt rankings, crawl budget, and user trust simultaneously. One scan of the deployed app sees all of it at once.
CheckVibe: $0 to try (4 full scans/month), $24/mo Starter, $59/mo Max with unlimited scans and custom monitoring. A comparable paid stack runs roughly $50–150/mo across 2–3 subscriptions — and still lacks AI-readability testing.
In the vibe-coding scanner space, no — Vibe App Scanner, VibeEval, and Scanbee are security-only as of June 2026; VibeWrench includes a basic 5-point SEO scan but no AEO. In the marketing-tool space, Semrush has an AI-visibility toolkit but no security scanning. The three-lane combination is currently unique to CheckVibe.
