How to Check if a Website is On Squarespace
If you’ve ever come across a beautifully designed website and wondered, “Is this built on Squarespace?”, you’re not alone. Whether you’re a designer looking for inspiration, a business owner comparing platforms, or simply curious about how a site was made, there are several reliable ways to identify a Squarespace website.
Below is a full breakdown of the most accurate methods, from checking the source code to using online tools.
Checking the Source Code
If you’re comfortable taking a more technical approach, the website’s source code can reveal a lot. Even when a site is heavily customized, Squarespace usually leaves behind certain tell‑tale signs in the backend.
How to inspect the source code
Right-click anywhere on the webpage and select “View Page Source” or “Inspect.” Use Ctrl+F (Windows) or Cmd+F (Mac) to search the code.
Look for terms that commonly appear on Squarespace sites, such as:
squarespace.com (often found in image URLs or scripts)
sqsp (a common abbreviation used in Squarespace code)
static.squarespace.com (frequently appears in hosted assets)
templateID (may reveal the original template)
If you see any of these, there’s a strong chance the site is built on Squarespace.
Keep in mind that some site owners intentionally hide or modify these identifiers, so the absence of these clues doesn’t automatically rule Squarespace out.
How to Identify the Squarespace Template
Once you’ve confirmed the site is using Squarespace, you may want to figure out which template it’s built on. Squarespace doesn’t offer a public template checker, but there are a few ways to make an educated guess.
Ways to identify a Squarespace template
Search the source code for templateID
Compare the site’s layout to Squarespace’s official template gallery
Use browser extensions like Wappalyzer, which sometimes detect template families
Check the footer — some sites still mention their template name
Template detection isn’t always perfect, especially with custom designs, but these methods can point you in the right direction.
Using Online Tools to Verify the Platform
If you prefer a quick, non‑technical method, several online tools can scan a website and identify the platform it’s built on.
Popular tools for CMS detection
BuiltWith — a detailed technology profiler
Wappalyzer — a browser extension that identifies platforms and frameworks
WhatCMS — a simple CMS checker
These tools are helpful, but not always 100% accurate. Highly customized Squarespace sites may not be detected.
Using a mix of visual clues, code inspection, and online tools gives you the most reliable answer.
When It’s Hard to Tell
Some Squarespace websites are so customized that they barely resemble the platform. If you’re having trouble identifying one, here are a few reasons why.
Why detection can be difficult
Custom domains hide direct references to Squarespace
Heavy CSS or JavaScript overrides mask the default structure
Third‑party plugins change the site’s appearance
Developers may intentionally remove platform identifiers
In rare cases, a site may even use multiple platforms together, which makes identification more complicated.
Why It’s Useful to Know a Website’s Platform
Understanding what platform a website uses can be helpful for many reasons.
Designers can learn which templates or layouts inspire them
Marketers can analyze competitor websites more effectively
Business owners can make informed decisions about their own platform
Curious users simply enjoy knowing how things are built
Once you know what to look for, identifying a Squarespace website becomes much easier.
