The technology reading
What is this website built with?
Paste any public address. We open the page, read what it volunteers about itself — the generator, the server, the paths its files sit under, the third parties it calls — and tell you what it is and roughly how old that build is. Useful on a competitor, useful on a site you have inherited, useful on your own.

How it knows
It reads what the page says about itself.
Most systems sign their work. WordPress writes a generator tag, Joomla and Drupal each have their own, servers send a name and often a version, and the paths that stylesheets and images sit under give away the rest. We read those, and nothing else.
That is a good answer and it is not a certain one, so we do not pretend otherwise. A generator tag is a line of text a page chose to publish: it can be removed, it can be left behind by a migration, and it can be wrong. What we report is what the page said, and where we can, what that string usually means.
- The generator, the server and what powers it, as sent
- The file paths a system gives itself away by
- Which third-party hosts the page reaches out to
- Roughly how old the named build is — the hook, and it is honest
What it will not do
A version number is not a vulnerability claim.
We will tell you that a page says it was built by a system whose named version came out several years ago. We will not tell you that this makes the site vulnerable, because that is a different statement: it depends on what is actually installed, what the host patches underneath, and what the version string was doing there in the first place.
And we will not go looking. We do not ask for files nobody linked to, we do not enumerate plugin paths, and we do not probe for versions. We read one answer your site gives every visitor — nothing your server has not already handed a browser.
- No path enumeration, no version probing, no login attempts
- No claim tying a version number to a weakness
- robots.txt honoured; a site that asks us to stay away is left alone
And then
Knowing what it is built with is how a migration starts.
The same detection runs at the front of a ReWynder rebuild, where it decides how the content gets out: a WordPress site can hand its content over through its own interface, a Joomla site through a connector, and anything else through an export or a straight read of the pages.
So the answer on this page is the first step of a route, not a novelty. If it says WordPress, there is a path. If it says something we have never seen, there is still a path — reading the pages works everywhere.
- WordPress, Joomla, Drupal, TYPO3, Magento and the site builders
- A connector where there is one, a read of the pages where there is not
Questions about the detection
How accurate is it?
It is as accurate as what the page publishes. A site that names its system in a generator tag is identified confidently; a site that has stripped every trace of itself may come back with very little, and we would rather say little than guess. Nothing here is inferred from a database of sites we have looked at before.
It says a version — is my site out of date?
It says the page published that version string. That is worth knowing and it is not the same as knowing what is installed: a host may patch underneath, a tag may be left over from a migration, and some systems keep the string of the branch rather than the release. Treat it as a lead, not a verdict.
Why does it not list my plugins?
Because finding them would mean asking your site for paths nobody linked to, and we do not do that to a website on a stranger’s say-so. What shows up here is what the page volunteered. Inside a rebuild, where you have told us the site is yours and connected it, the picture is much fuller — and it comes from your own system rather than from guessing.
Can I check a site that is not mine?
The technology, search-engine and accessibility readings, yes — they are read from one ordinary page load, and none of them names a weakness somebody could use. The security reading is different and needs you to declare that the site is yours.
Does it work on a site that is not a CMS?
Yes. A hand-built site, a static site, a framework, a shop platform — we report what the page says. Where there is no generator at all we say that too, which is itself informative.
