We built a free Website Analyzer tool that lets you scan any URL and get a detailed breakdown of its security posture, SSL configuration, technology stack, and more. No login required — just paste a URL and hit scan.
What It Scans
SSL Certificate Details
See who issued the certificate, when it was issued, when it expires, and how many days you have left. If the site has SSL issues (expired, self-signed, or misconfigured), the analyzer will flag them immediately.
Security Headers
The analyzer checks for all the important security headers — Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, and the Cross-Origin headers (COOP, CORP, COEP). You'll see which headers are present and which are missing.
Technology Stack
Find out what's powering any website. The analyzer detects over 20 technologies including:
- Frameworks: Laravel, WordPress, Drupal, React, Vue.js, Next.js, Angular
- JavaScript libraries: jQuery, Bootstrap JS, Alpine.js
- CSS frameworks: Tailwind CSS, Bootstrap, Bulma
- Server software: Nginx, Apache, LiteSpeed, IIS
- CDN providers: Cloudflare, CloudFront, Fastly, BunnyCDN, Akamai, KeyCDN
Page Information
Get the page title, meta description, final URL (after redirects), response time, and content size at a glance.
How to Use It
- Go to the Website Analyzer (available under Tools in the navigation menu)
- Enter any URL
- Click Analyze
- Review the results
That's it. No signup, no API key, no rate limit surprises (though we do limit to 5 scans per minute to keep things fair).
Use Cases
- Check your own site's security — Find out if you're missing critical security headers before an auditor does
- Vet a new service — Wondering what technology a SaaS product uses? Scan it
- Competitive research — See what tech stack your competitors are running
- SSL verification — Quickly check if a site's SSL certificate is valid and when it expires
- Pre-purchase due diligence — Buying a website? Check what you're getting into
Browser Mode
For sites behind WAF protection (Cloudflare challenges, bot detection, etc.), toggle on Browser Mode. This uses headless Chrome to load the page like a real browser, bypassing JavaScript challenges that would block a standard HTTP request.
Browser Mode is available on Pro and Expert plans and works across the Website Analyzer, Redirect Checker, Content Checker, and Security Scanner.
Try It Now
Head to the Website Analyzer and scan your first site. It takes about 5 seconds and you might be surprised by what you find.
