From the home page, read once just now, and public records: the domain's DNS, and the registries' own records of who holds each domain name and network (RDAP).

How we can tell
We read the home page once and look for clear signs only:
- A name in the page's code. Most builders write their name into every page, where visitors don't see it.
- A note from the server. Some platforms say who they are with every page they send.
- Files only one builder uses. Pictures and code loaded from that builder's own servers.
If none of those show, we say we couldn't tell rather than guess. Sites made by hand, and sites that hide what made them, look the same from outside.
Builders we can spot
WordPress, Drupal, Joomla, Squarespace, Wix, Shopify, Webflow, Weebly, GoDaddy's website builder, Ghost, HubSpot, TYPO3, Concrete CMS, Craft CMS, Umbraco, Sitecore, Duda, Framer, Jimdo, Blogger, Hugo and Jekyll.
Why it helps to know
- Help pages. Every builder hides its settings in different places. Search for your builder's name with "how to" and you'll find the right steps.
- Who to call. On Squarespace, Wix and Shopify the builder hosts the site too, so its support is the first call. On WordPress and Drupal it's whoever built the site, or your web host.
- Free help from us. PageKiwi for WordPress and PageKiwi for Drupal check your site from the inside, and our guides have steps for Squarespace, Wix and Shopify.
How to use it
- Type the website's address, like YourWebsite.com. Any site works, not only your own.
- Press Find out. It takes a few seconds.
- The first row names the builder, if we could tell, with our guides for it. The rows below say who hosts the site, its domain and its email.
What your results mean
- Built with
- The website builder or software that made the site. We name one only when the home page shows clear signs.
- We couldn't tell
- No clear signs. The site may be made by hand, or hide what made it.
- Where the website is hosted
- The company that owns the network the site is on, exactly as the registry records it.
When to use it
- You've taken over a website and nobody told you what it's built on.
- Before you hire someone to change it: it's one of the first things they'll ask.
- Help steps you've found don't match the menus you see.
- You like another site and wonder what made it.
Why it matters
- Help steps differ from one builder to the next, so knowing yours gets you to the right ones.
- A web person can quote sooner, and closer to the real cost, when they know what they're taking on.
