About CheckVibe
Last updated: July 3, 2026
CheckVibe is a free, all-in-one website scanner for vibe-coded sites and apps. A single scan audits your site across eight pillars — security vulnerabilities, exposed API keys, SEO, AI visibility (AEO), performance, accessibility, email deliverability and domain health — and returns every issue with a concrete, copy-paste fix. You only pay if it finds issues worth fixing.
Why we built it
More software than ever is shipped by people who aren't full-time security engineers — founders, designers and developers building fast with AI coding tools like Cursor, Copilot, Lovable, Bolt and v0. That speed is a gift, but it routinely ships sites with exposed secrets, missing access controls, broken structured data and poor Core Web Vitals. CheckVibe exists to close that gap: enterprise-grade auditing that anyone can run in seconds, with fixes written in plain language.
How the scanner works
CheckVibe crawls your live site and runs dozens of independent checks against the published web standards below. Findings are confidence-rated and de-duplicated, then paired with a remediation you can apply at the edge, in DNS, on your platform, or in code. Paid plans add scheduled re-scans, alerting and an MCP server so AI agents can run audits and apply fixes directly.
- OWASP Top 10 — the web application security risks our vulnerability scanners map to.
- Google Search Central — the technical SEO and structured-data rules our SEO audit checks.
- Core Web Vitals (web.dev) — the field performance metrics our Performance pillar measures.
- Schema.org — the structured-data vocabulary our rich-result validator follows.
- WCAG 2.2 (W3C) — the accessibility success criteria our WCAG audit evaluates.
- DMARC.org — the email-authentication standards our deliverability checks verify.
- GEO: Generative Engine Optimization (Princeton et al., arXiv:2311.09735) — the research on AI-answer visibility that informs our AEO checks.
Who it's for
Indie hackers and vibe coders who want a safety net before launch, agencies auditing client sites, and teams who want continuous monitoring without standing up a security program. If you can paste a URL, you can run a full audit — no repo access required, though connecting GitHub or Supabase unlocks deeper backend checks.
