QUESTIONS

What is this website built with?
Enter a domain in the lookup above. Stack identifies supported technologies on its homepage and groups them by category. Each successful result includes the time of the check. Developers can request the same data as JSON with GET /stack/{domain}.
Can I use Stack as a CMS checker?
Stack identifies CMS platforms including WordPress, Drupal and Webflow, plus ecommerce tools such as Shopify and WooCommerce. Stack also detects frameworks, analytics, chat, payment tools and hosting services. The coverage section lists all 36 supported technologies.
How does the tech stack checker work?
It checks one public homepage, following permitted redirects. Detection uses the returned HTML and response headers. Technologies loaded only after JavaScript runs or on another page may be absent. Versions are included when explicitly identified.
How fresh is the result?
Successful checks can be reused for up to 24 hours. The checked_at timestamp identifies the original check. Blocked or unavailable checks can be retried after 15 minutes. An empty list means no supported technology matched that category. Every category is a list, including CMS platforms and servers. If no page could be checked, category lists and checked_at are null. The response names its scope, counts checked pages and marks partial inventories.
