See what any website is made of.
A free report on SEO, speed, security, accessibility and the technology behind any page.
What the report checks
Hosting
Identifies the hosting provider and infrastructure location when the headers reveal it.
Domain
Reads public registration and DNS data, with a fallback when registrars hide it.
Tech stack
Detects frameworks, CMS platforms, programming languages, and front-end libraries.
Content
Checks page structure, headings, meta descriptions, and Open Graph tags.
Sitemap
Looks for XML sitemaps and robots.txt to understand how a site is organised for crawlers.
Security
Reviews HTTP security headers such as CSP, HSTS, and X-Frame-Options.
Performance
Measures response time, page weight, and render-blocking resources.
Accessibility
Flags missing alt text, poor contrast, and skipped heading levels.
Mobile
Evaluates viewport configuration, touch targets, and mobile-specific metadata.
Third-party services
Spots analytics, advertising, chat widgets, payment processors, and CDNs.
SEO
Audits canonical URLs, hreflang, structured data, and indexability signals.
How scoring works
The overall score is a weighted average across five categories: Security 25%, Performance 25%, SEO 20%, Best Practices 15%, and Accessibility 15%.
Grades run from A down to D. A high score means the site is doing most things well; a lower score simply points to the areas that will benefit from attention first.
When a site sits behind an enterprise CDN or firewall that hides technical details, the report says "Based on available data" instead of guessing.

Questions people ask
Why do some things say 'Not detected'?
Some technologies, headers, or services only reveal themselves in specific files or responses. When the evidence isn't there, we report 'Not detected' rather than guess.
Is 'Limited data' a bad sign?
Not at all. It usually means the site sits behind an enterprise CDN or firewall that deliberately hides technical details. That is a common and sensible security practice.
How fresh is the data?
Each report is generated live when you run the analysis. We cache complete results for a short time to keep the tool fast, but a fresh scan always fetches the latest publicly available data.
Can this tool be used maliciously?
No. The analyzer only looks at publicly available information that any visitor can access. It does not attempt to bypass security, log in, or probe non-public areas.
