Your questions, answered

How does the CRFT Lookup compare to Pingdom?

While Pingdom's Website Speed Test offers basic performance monitoring, CRFT Lookup provides more comprehensive analysis through Google Lighthouse metrics that evaluate not just speed but also best practices, SEO, and accessibility. Our platform delivers detailed performance insights alongside technology detection and meta tag previews, all available for free.

Is the CRFT Lookup really free?

Yes, the CRFT Lookup is completely free to use. You can perform unlimited scans and access all features including technology detection, performance analysis, and meta tag previews without any cost to you. So how do we make money? We sell web design and development services.

How accurate is the technology detection?

Fairly accurate. When you input a URL, we spin up a headless instance of Chromium, visit the website and analyze its HTML, JavaScript variables, response headers and more. Then, we compare them against our database of over 2,500 technology fingerprints to identify frameworks, CMS platforms, analytics tools, and infrastructure technologies. Our detection engine is regularly updated to stay current with new versions and emerging technologies. While no detection system is perfect due to obfuscation and custom implementations, we maintain high accuracy by using multiple detection methods and continuous updates to our pattern matching algorithms.

Can I save or share my reports?

Yes, all reports generated by the CRFT Lookup are automatically saved and shareable via a unique URL. Reports are retained for 30 days and include all analysis data: detected technologies, Lighthouse performance scores, and meta tag previews. This makes it easy to share reports with a friend, teammate, or client.

What information does the CRFT Lookup provide that Pingdom doesn't?

While Pingdom's Website Speed Test focuses on basic performance metrics, CRFT Lookup provides a broader analysis through Google Lighthouse. Beyond just speed measurements, we evaluate accessibility, SEO, and development best practices. We also include comprehensive meta tag previews to show how your site appears across different platforms, delivering more complete insights about your website's technical profile.
