You can suggest a new technology. We only accept web technologies with an established user base.

Where possible, we find the associated company and use the location of their main office. We may also infer country from the website's top-level domain, phone numbers listed on the website, a lookup on the website's IP address or other methods.

We collect limited information through our browser extension in accordance with our privacy policy and perform in-depth analysis using in-house crawlers. Our unique methods ensure only actively visited websites are included in the lists, including pages that traditional crawlers can't reach.

Our technology data is of a very high standard and corroborated across multiple sources. Email addresses and phone numbers obtained from websites' contact pages are provided on an as-is basis.

Our dataset is continously updated and we aim to re-verify the identified technologies on every website at least once a month. Company details are refreshed quarterly.

Website traffic is tracked using our browser extensions with over 2.5M users. The install base provides a large enough sample set to determine which websites receive more traffic than others, resulting in a relative traffic indicator.

Reselling or sharing our data is prohibited by our terms of use. If you're an Enterprise customer and would like to apply for an exception, please contact us.
