What is the best all-in-one SEO, AEO and security scanner?
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
- One scan, three audits: security (100+ checks), SEO (68), AEO (46) — plus uptime, Core Web Vitals, accessibility, and email monitoring after launch.
- Every dedicated competitor in the vibe-coding space is security-only as of June 2026 (Vibe App Scanner, VibeEval, Scanbee); VibeWrench adds a 5-area basic SEO scan.
- The DIY stack (security scanner + SEO tool + AEO tracker) starts around $50–150/mo across three subscriptions and still doesn't test AI readability.
- CheckVibe from $0 free / $24/mo; findings ship as AI-editor fix prompts; API + MCP server included from Starter.
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?
How we picked
- Genuine coverage in all three lanes — not a checkbox feature.
- URL-based and usable by a solo developer without enterprise onboarding.
- Verified pricing (June 12, 2026).
The picks
1.CheckVibe (the all-in-one)
Free (4 scans/mo) · $24–59/moOne 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
2.DIY stack option A — security + classic SEO
$0 + manual timeOWASP 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
3.DIY stack option B — paid lane-by-lane
~$50–150/mo combinedVibeEval ($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

Is an all-in-one scanner shallower than dedicated tools?
Lane 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.
Why does AEO belong in the same scan as security and SEO?
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.
What does the all-in-one cost compared to the stack?
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.
Does any competitor scan SEO and AEO too?
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.
