What Is My Website Built With? How to Check in Seconds

You don't need your developer, a password, or any technical skill to find out what your website is built with. Every site broadcasts clues in its code and its public domain records, and free tools read those clues for you. Paste in your web address and within seconds you'll know the platform, the plugins, the hosting company, and the domain registrar. Here's how to do it and what each answer means.

People ask us this for all sorts of reasons. Maybe you inherited the site from a previous owner. Maybe the person who built it stopped answering emails. Maybe you're just getting a quote and want to sound informed. Whatever the reason, the check itself takes about a minute.

What you'll need

• Your website address (for example, yourbusiness.com). That's it.
• A web browser. Any device works, including your phone.
• About one minute. No login, no install, nothing to download.

How to check what your site is built with

1. 1Open a free "built with" detector. These tools scan your site's public code and read the fingerprint that every platform leaves behind. You can use ours at Built With.
2. 2Paste in your web address and run the check. In a few seconds you'll see the platform, and often the specific theme and plugins the site is running.
3. 3Read the platform line first. This is the big one. It'll say something like WordPress, Wix, Squarespace, Shopify, or Webflow. That single word tells you how your site gets updated and who can help you with it.
4. 4Scan the hosting and domain rows. A good detector also shows your hosting company, server location, nameservers, DNS provider, and the registrar where your domain lives. Those are the accounts you'd need access to if you ever moved.
5. 5Note anything you don't recognize. If the host or registrar is a company you've never heard of, that's usually a sign your developer set everything up under their own account. Worth knowing now, not later.

What the platform actually tells you

The platform is more than trivia. It decides how much of your site you can manage yourself and who you'd hire if you need help.

If the tool couldn't detect anything, don't panic. Some sites sit behind a security service like Cloudflare that masks the fingerprint. It usually still shows the host and registrar, which are the details that matter most if you're trying to take control of a site. For the wider question of what can go wrong and how to spot it, our website problems hub walks through the common ones.

When you'd rather someone else keep track of all this

Knowing what your site is built with is step one. Keeping it updated, backed up, and secure month after month is the ongoing part, and that's the piece most busy owners quietly let slide. Our maintenance plans start at $99 a month and cover exactly that: platform and plugin updates, off-site backups, uptime monitoring, and a real person who already knows your setup when something needs attention.

We're a Seattle-area studio and we've been maintaining small-business sites since 2011, both across the Puget Sound and for clients around the country. If you'd like a straight read on what your site is running and what it needs, that's an easy first conversation.
