What technology
is under the hood?
Enter a URL — the detector fetches the page server-side and identifies framework, CMS, hosting, analytics and CSS framework. No signup, no third-party APIs.
What the Tech Stack Detector recognizes
The detector analyzes a page's HTML, headers and script signatures to identify the technology in use: CMS or framework (WordPress, Next.js, Shopify, Wix …), server and CDN, analytics and marketing tools, font and icon services, and hosting hints.
That's useful in several situations: you want to know what your own site actually runs on because a previous agency built it. You're checking what legacy pieces would carry over before a relaunch. Or you want to gauge what setup comparable businesses work with.
The check only reads publicly visible signals — it doesn't log in anywhere and doesn't bypass any protections. Not every technology leaves unambiguous traces; the result therefore only names what can be verified with confidence.
Frequently asked questions
Why doesn't the check recognize my CMS?
Some setups (headless CMS, heavily cached pages, removed meta tags) leave few signatures. The check prefers naming less over naming wrong things — no match means no clear traces, not necessarily no technology.
Is scanning other sites allowed?
The check only fetches publicly accessible pages, like any browser does, and evaluates their source. It doesn't bypass access restrictions.
What does the stack tell me about a site's quality?
Little directly — good sites are built on many stacks. It's interesting as context: outdated versions, many marketing scripts or heavy page builders often explain why a site is slow or hard to maintain.
