50+ Live Real Checks
Powered by PHP + AI

Every test uses real cURL requests, live HTTP header inspection, and DOM parsing — zero simulation.

Deep SEO Analysis

Live checks for meta titles (length), descriptions, canonical URLs, H1 usage, heading hierarchy, robots directives, sitemap existence, keyword alignment, and alt-text keyword stuffing.

Core Web Vitals & Performance

Measures real TTFB, checks GZIP/Brotli compression, CDN detection, HTTP/2, Cache-Control headers, render-blocking scripts, lazy loading, and HTML document size.

WCAG 2.1 AA/AAA Accessibility

Validates lang attribute, alt text, form labels, skip links, ARIA landmark roles, empty buttons, new-tab warnings, iframe titles, and tabindex anti-patterns.

Security Header Scan

Real HTTP header inspection for CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, mixed content, eval() usage, and exposed server versions.

Mobile Responsiveness

Checks viewport meta tag, user-scalable restrictions (WCAG violation), fixed-pixel overflow, Apple touch icons, Web App Manifest, and theme-color meta.

Live Broken Link Checker

Fetches up to 30 links via cURL, detects 404/410 errors, redirect chains (multiple hops), slow-responding links, and missing rel="noopener" on external links.

Cookie Security Audit

Inspects Set-Cookie response headers for Secure, HttpOnly, SameSite attributes, and excessive expiry durations — real server response analysis.

DNS & Server Analysis

Checks HTTP→HTTPS redirect consistency, www/non-www canonicalisation, CDN presence, server version exposure, and response time benchmarking.

HTML Quality Validator

Detects missing DOCTYPE, missing charset, deprecated tags (&lt;font&gt;, &lt;center&gt;, &lt;marquee&gt;), duplicate IDs, <style> in body, and counts DOMDocument parse errors.

Typography & Font Audit

Detects Google Fonts without preconnect hints, missing display=swap parameter, @font-face without font-display, and problematic line-height values.

Structured Data Validator

Checks for JSON-LD presence, validates @context and @type properties, detects missing BreadcrumbList, and reports JSON syntax errors.

Beautiful PDF Reports

One-click download of a fully branded PDF with score ring, category bars, full issue list with severity badges, and step-by-step fix recommendations for every finding.

What is an AI Website Tester?

An AI website tester is a next-generation web auditing tool that applies server-side intelligence to systematically evaluate every technical, structural, and content dimension of a webpage in real time. Unlike static checkers, our tool performs live HTTP requests via PHP cURL — reading actual response headers, parsing the real DOM, and running over 50 checks against your live server. To use this free online website testing tool, simply enter a URL, choose your test categories, and click Analyze. Within seconds you'll receive a comprehensive audit covering SEO (meta tags, canonicals, sitemaps), Core Web Vitals (TTFB, GZIP, caching), WCAG 2.1 accessibility (alt text, labels, ARIA roles), security (CSP, HSTS, XSS vectors), mobile usability (viewport, touch targets), live broken link detection, cookie security attributes, DNS configuration, HTML quality validation, and typography best practices. The best practice for using an AI website audit tool is to run it after every significant update, before major launches, and on a regular monthly schedule to catch regressions early. Developers, SEO professionals, and digital marketers rely on these insights to maintain competitive search rankings, protect users, and deliver fast, inclusive web experiences across all devices.

Frequently Asked Questions

Everything you need to know about our live AI website testing tool.

An AI Website Tester automatically audits any webpage using real server-side PHP requests. It tests SEO, performance, accessibility, security, broken links, DNS, cookies, HTML quality, typography, structured data, and more — then generates a scored report with prioritised fix recommendations.
100% live. Our PHP backend fetches the actual URL via cURL, reads real HTTP response headers, parses the live DOM with DOMDocument, and performs genuine checks — including live HTTP requests to verify broken links, sitemap existence, and robots.txt availability.
Most sites complete in 15–30 seconds. The broken link checker fetches up to 30 links individually, which accounts for most of the time. Slow-responding websites naturally take longer.
It validates: lang attribute on <html>, alt text on images, form input labels, skip navigation links, ARIA landmark roles (<main>, <nav>), empty buttons, iframe title attributes, new-tab link warnings, and tabindex anti-patterns — all against WCAG 2.1 Level A and AA success criteria.
Yes. After analysis, click "Download PDF" for a full branded report including your overall score, category score bars, every issue with severity badge, description, and step-by-step fix recommendation.
Real HTTP header inspection for: Content-Security-Policy, X-Frame-Options, Strict-Transport-Security (HSTS), X-Content-Type-Options, Referrer-Policy, Permissions-Policy, mixed HTTP content on HTTPS pages, server version disclosure, PHP version in X-Powered-By, eval() and document.write() usage, and inline event handler overuse.
It reads actual Set-Cookie response headers and flags cookies missing the Secure flag, HttpOnly flag, or SameSite attribute, plus cookies with excessively long expiry durations (>1 year) that may conflict with GDPR/CCPA requirements.
After every significant deploy, before major launches, and at minimum monthly. High-traffic or e-commerce sites benefit from weekly audits to catch performance regressions, broken links, or security header changes.
