What is jQuery?

jQuery is a long standing JavaScript library for DOM work and Ajax. It is still common on older and CMS sites.

In the tech stack detector, jQuery shows up in the JavaScript group. Knowing a site runs jQuery tells you how it is built and what it is set up to do.

How to detect jQuery

Look for jquery.min.js in the page scripts or a global jQuery object.

You do not have to dig through page source by hand. Paste the website into the detector above and it reports jQuery along with the CMS, analytics, pixels, hosting, payments, chat, email, and CRM the site uses.

Why it matters for agencies

Knowing a prospect runs jQuery (or does not) shapes your pitch. The detector also flags the gaps: if a site has no CRM, no chat widget, no review tool, or no ad pixel, that is a clear opening for a GoHighLevel CRM, an AI chat or voice agent, review automation, or a paid ads setup.
