What's your website built on?

Type in any website and we’ll look under the hood: WordPress, Wix, Squarespace, GoHighLevel, Webflow, Shopify and 31 more. Then see what that means for your speed, your Google rankings and whether you can take it with you.

We only read the public homepage, the same code any browser sees. Nothing is saved.

The big picture

Most websites run on one of a few families.

WordPress alone runs 40.7% of all websites, and 30.9% use no system we can name at all (often custom code). Among sites that do use one, Shopify has 7.6% of the market, Wix 6.1% and Squarespace 3.5%, with Webflow and Duda around 1% each. Builders in the same family work the same way underneath, so here’s every builder the tool knows, grouped by how it works.

WordPress

Free software you install on a web host, then add a theme and plugins.

WordPress

Other install-it-yourself systems

Like WordPress: software on a web host, a database, and add-ons that each need updates.

Joomla, Drupal, Ghost

Drag-and-drop builders

All-in-one: you rent the builder, the hosting and the templates together, for a monthly plan.

Wix, Squarespace, GoDaddy Website Builder, Weebly, Square Online, Hostinger Website Builder, Jimdo, SITE123, Strikingly, Webnode, Tilda, Carrd, Google Sites

Designer tools

Visual tools made for designers. More design freedom and cleaner code than drag-and-drop builders, still hosted on their platform.

Funnel and CRM platforms

Marketing software with a page builder inside. Built for funnels and lead capture first, websites second.

GoHighLevel, ClickFunnels, Kajabi, Kartra, Systeme.io, HubSpot CMS

Online store platforms

Built to sell products: cart, checkout, payments and inventory, with a website around them.

Shopify, BigCommerce

Agency and industry platforms

A marketing company builds and hosts the site for you, often on its own or a white-label platform, tied to a contract.

Duda, Scorpion, FindLaw (LawyerMarketing.com), Justia, Hibu, Thryv

Custom code on a modern framework

Hand-built by a developer on a modern framework. The same family as ours.

Next.js, Astro, Gatsby

Market share figures: W3Techs, August 2026 (all websites) and July 2026 (share of sites using a known system).

Why we built this

Your builder decides more than how your site looks.

It decides who controls your speed and your SEO settings, what you pay every month to stay online, and what happens if you ever want to leave. Most owners have never been told. This tool is the conversation we have on almost every call, written down so anyone can use it.

If you’re weighing a new site, here’s how our High-Performance Websites work, and why we wrote about keeping a website secure.

Questions

Good questions people ask about website builders.

How do you know what a website is built on?

Every builder leaves fingerprints in a site's public code: the servers its images and scripts load from, tags it adds to every page, and notes in the server's response. The tool reads the homepage, the same code any browser sees, and matches those clues. It shows you which clues it found, so you can see how it knows.

Why does it matter what my website is built on?

It decides who controls your speed, your SEO settings and your security, what you pay every month, who can make changes, and whether you can take the site with you if you leave. Two sites can look the same and work completely differently underneath.

Is WordPress bad?

No. It runs about 4 in 10 websites, you own it, and it can be excellent. The catch is upkeep: WordPress, PHP, the theme and every plugin need regular updates, and heavy page builders can slow it down. A well-cared-for WordPress site beats a neglected anything.

Is Webflow better than Wix or Squarespace?

For designers, often yes: more design freedom and cleaner code. For an owner who wants to make edits themselves, Wix and Squarespace are easier. All three host your site on their own platform, so you pay a plan to keep it online. Webflow can export page code on its Workspace plans, but not your blog or CMS content.

Can I move my website off Wix, Squarespace or GoHighLevel?

Usually by rebuilding it. Most hosted builders don't let the site itself leave their servers, though your words, photos and domain are yours to bring. When we rebuild a site, we redirect every old page address so your Google rankings carry over.

What are JDS1 websites built on?

Next.js, the framework made by Vercel, hosted on Vercel's global network. Every page is built ahead of time, the code lives in GitHub with a history of every change, and each change gets a private preview and a person's approval before it goes live. You own your content and your domain.

The tool couldn't tell what my site is built on. Why?

Some sites block tools like this one, and some are custom-built or hide their builder well. Pick your builder from the list instead. If you don't know it, whoever built or hosts your site can tell you, or we can look with you on a call.
