Web Check - Complete Website Analysis

What is Web Check?

Web Check is a free all-in-one website analysis tool. Enter any URL and it runs a full battery of diagnostics in one pass — instead of jumping between a DNS lookup, an SSL checker, a headers inspector and a speed test, you get every result on a single page. It is built for developers, sysadmins, SEO specialists and site owners who want a fast, honest snapshot of how a website is configured and how it behaves from the outside.

All checks are performed server-side against the public-facing site, exactly as a visitor's browser or a search-engine crawler would see it. Nothing is stored: each analysis is run on demand and the results are yours to read and discard.

What Web Check inspects

• DNS & hosting — A/AAAA records, nameservers, the resolved IP and where it is hosted.
• SSL/TLS certificate — issuer, validity dates, days until expiry and whether the chain is trusted.
• HTTP response headers — status code, redirects, server software and security headers such as HSTS, CSP and X-Frame-Options.
• Performance — response time and page weight, so you can spot a slow or bloated page at a glance.
• SEO & social meta — title, meta description, canonical, Open Graph and Twitter Card tags.
• Mobile & accessibility signals — viewport configuration and other front-end basics.

How to use it

1. Paste a full domain or URL (for example https://example.com) into the box above.
2. Press Enter or click the analyse button.
3. Read the grouped results — each section can be scanned independently, and problems are highlighted so you know what to fix first.

Run it before a launch to catch a missing security header or an expiring certificate, after a migration to confirm DNS and redirects resolve correctly, or periodically to keep an eye on a site you maintain.
