Website Technology Checker
Find out what a website is built with. We read the live page and report the platform, framework, web server, CDN and analytics we can see. A complimentary tool from Squish — no signup.

What a page tells you about itself
Every site announces more than its owner usually realises. The server and CDN sign their own response headers, a CMS leaves its asset paths all through the HTML, and analytics scripts name themselves in the markup. None of it is hidden — it is the same data every visitor's browser receives, just read deliberately. That makes this useful for sizing up a migration, checking what a contractor actually built, or working out why a site behaves the way it does.
Common questions
How does this work?
We request the page the way a browser would, follow any redirects to the page that is actually the site, and look for markers in the response headers and the HTML — a wp-content path, a generator tag, a CDN's own header. It is pattern matching on what the site chooses to send, not a scan of anything private.
Why does it say the platform is not detected?
Because nothing in the page said so. A hand-built site genuinely has no CMS to find, and a heavily cached or bot-challenged page may not give us the real HTML at all. We would rather say we did not find it than pick the most likely guess and present it as a fact.
Why does the result mention a different address than the one I typed?
Most domains redirect — typing example.com usually lands on www.example.com. The page that gets read is the one at the end of the redirect, so that is the one we name. Reporting the address you typed would attribute another page's technology to it.
Can I use this to check a competitor?
Yes, and everyone does — it only reads what any visitor's browser already receives. It will not tell you anything the site keeps private, and it says nothing about how well any of it is set up.
Moving off whatever this says? Squish migrates sites without downtime and hosts them once they land — the platform stays yours, the server stops being your problem.
