About WebScanReport

What it checks

You paste a URL. Five audits run in parallel and produce one report with a prioritised list of fixes, each with its impact, the effort involved and a concrete solution.

• SEO — meta data, headings, links, canonical, robots, sitemap and readability.
• Performance — Core Web Vitals from a full Lighthouse run against headless Chrome.
• Accessibility — WCAG violations found with axe-core on the rendered page.
• Security — TLS certificate, security headers, mixed content and cookie flags.
• AI Readiness — how well AI assistants and answer engines can read, understand and cite the page.

How the scores are produced

Every check runs on our own server. Performance comes from Lighthouse, accessibility from axe-core, and the SEO, security and AI-readiness findings from a rule engine written by hand. Each rule states what it looks at, why it matters and what to do about it.

No third-party AI service is involved in producing a score, and that includes the AI Readiness score. It is a deterministic calculation over six weighted pillars: structured data, content, entities, semantics, trust signals and crawlability. Run the same page twice and you get the same number.

Why it is free

It is built entirely on open-source software and runs on a single server, so it costs little to keep going. Scanning and the scores need no account; the findings and the exports come with a free one. There is no paid tier, no trial and no credit card. If it saves you time, there is a donation link in the footer.

Who runs this

One person, as a side project. That is worth knowing when you decide how much to lean on it: there is no support desk and no uptime guarantee. What you can rely on is that every verdict comes from a rule you can read in the report itself — each finding states what was measured, why it matters and what to do about it.
