Questions
What is a tech stack checker?
A tool that looks at a website from the outside and lists the technology it runs on: its CMS or store platform, theme, hosting, CDN, analytics, marketing tools and more. It reads the same things your browser receives, so it works on any public site.
How do I find out what technology a website uses?
Type its address into the box above for the full report, or pick a detector below for a quick answer to one question. Each detector checks the homepage live and links to the full report.
How does the checker know what a site is built with?
Every tool leaves fingerprints: script URLs, cookies, response headers, meta tags, DNS records and the network its IP address belongs to. We match those against rules for thousands of tools.
Is it free?
Yes. There's no sign-up, no browser extension and no limit on lookups.
