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.
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.
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.
