Frequently asked questions
Everything you need to know about the Website Technology Checker.
Back to the toolHow does the technology checker work?
It loads the page like a browser and looks for known fingerprints in the HTML, response headers, cookies and script URLs.
Can it detect every technology?
No tool can detect everything. Server-side tools that leave no trace in the page (like a database) can only be guessed. Results show how each item was detected.
Can I find which WordPress theme a site uses?
Popular themes and page builders like Astra, Divi, Avada and Elementor are detected automatically.
Why do I get an error for some sites?
Some websites block automated requests or require JavaScript to show content. Try the full URL with https://.
Is this legal?
Yes. It only reads information that the website sends publicly to every visitor.
