Frequently asked questions

What is a website technology stack?

A website's technology stack is the set of software it runs on: the CMS or framework, JavaScript libraries, analytics and tag managers, payment and e-commerce tools, hosting and CDN. Knowing a site's stack helps with competitor research, sales prospecting and planning a migration.

How does website technology detection work?

Detectors look for fingerprints a site leaves in public: script and stylesheet URLs, HTML meta generator tags, cookies, HTTP headers and DNS records. Each fingerprint maps to a known product, sometimes with a version number.

Can I find out what CMS a website uses?

Yes. Content management systems such as WordPress, Shopify, Wix and Drupal leave clear markers, so they usually show up under their own category in the results. Sites that hide or strip these markers may show fewer results.

Where does the lookup run?

On OpenTools' servers, not in your browser. You only enter a public URL, so nothing is installed on the target site and you do not need a login or any access to it.
