TechStack Checker.
Detect any site's tech.
Paste a URL to detect a site's technologies in seconds. Clear, categorized results for an audit, a competitive check, or plain curiosity.

Paste a website address above and press Analyze.
Features
What this gives you that a page source view does not.
Grouped, not dumped
Results arrive as categories: the CMS, the framework, the analytics, the hosting. Not one long list of names.
Rendered, not guessed
The page is actually loaded, so technologies that only appear after the scripts run are still detected.
Useful against scam networks
A template shared across unrelated domains is one of the strongest signals a cluster exists. This is where you see it.
How it works
Three steps, no account.
Paste an address
A domain or a full URL. We reduce it to the host ourselves.
We load the page
Properly, in a browser, which is why it takes about fifteen seconds.
You get the stack
Every technology we can confirm, grouped by what it does.
Commonly detected
The stacks that come up most often. A shared template across unrelated domains is one of the signals our scam network detection is built on.
