The jQuery CDN lists the latest stable build of each jQuery Core branch, plus jQuery UI, jQuery Mobile and QUnit. Each build has its own link.[1]
jQuery CDN is a content delivery network specifically designed to serve the popular jQuery JavaScript library. It allows developers to include jQuery in their websites without downloading and hosting the library on their own servers. By leveraging a CDN, websites can benefit from improved load times as users may already have the jQuery file cached from visits to other sites using the same CDN. jQuery CDN offers various versions of the library, allowing developers to choose the one that best suits their needs. It supports both HTTP and HTTPS protocols and provides fallback options to ensure the library is loaded even if the CDN is temporarily unavailable. This service is an excellent choice for developers looking to optimize their website's performance while using jQuery.

Rough guide, not a measurement: each description is written automatically from the site’s technology stack and the site has not confirmed it. A site is counted once, in the first group its description fits (shop, help and docs, blog, marketing site; otherwise the whole site). Descriptions that only guess (“likely”, “may”) are left out.

Its story
2013
jQuery 2.0.0 files were published on the CDN. This branch dropped Internet Explorer 6, 7 and 8, so sites needing those browsers stayed on 1.x.[2]
2016
jQuery 3.0 added a slim build without ajax and effects to the CDN. Sites that use other libraries for those jobs can load less code.[6]
2019
jQuery 3.4.0 was expected to be the last minor release of the 3.x branch before the work on jQuery 4.0. Its files were served from the CDN first.[7]
2023
jQuery 3.7.0 folded the Sizzle selector engine into jQuery itself. The library no longer depends on a separate Sizzle project.[8]
2026
jQuery 4.0.0 is the first major release in almost ten years. It drops IE 10 and older and uses ES modules, and its files are on the CDN.[3]
