Companies Using jQuery Mobile

jQuery Mobile is a strange row to analyse: a framework its own maintainers deprecated in 2021 that still sits on 287,539 domains in our October 2026 crawl, with 201,818 of them matched to a company, a 70.19% match rate. I wanted to know who chooses it. In our sample, about 3% of live pages did; for the rest, a WordPress theme or plugin made the choice.

What the signal catches

A domain counts when a page defines jQuery Mobile's version property or loads a script named like jquery.mobile.js or jquery-mobile.min.js. That second clause is the one that fires on most sites, and the file usually isn't where you'd expect. I sampled 1,497 clean domains and fetched each on 16 October. Of the 1,339 live pages, 1,060 (79.2%) were Divi sites; on 935 of them the jQuery Mobile file loaded straight from Divi's own folder, and the rest had Divi with combined or renamed scripts. Another 69 got it from 10Web's Photo Gallery, Slider and Facebook Feed plugins, 49 from the EventON calendar and 19 from Serious Slider. Only 40 pages (about 3%) served their own copy or a CDN copy outside WordPress. Divi's file even confuses the version field: in the same sample, 1,086 detections recorded a "version" that starts with 4 or 5, which is the theme's or plugin's version from the ?ver= query string, not a jQuery Mobile release.

The dead-page check came in under our threshold. 19 sampled domains no longer resolved and 13 were error, suspended or default pages, 32 of 1,497 (2.14%), and we found no gambling cluster. (Our technology detection methods post explains how script-path rules like this one are matched.)

Sales signal: a jQuery Mobile hit is, four times out of five, a Divi detection. Sell to it as a Divi site.

Growth trajectory

The chart reads 243,285 domains in June 2026 and 287,539 in October. I wouldn't call that growth. The set of domains we crawl turns over every month, with dead sites dropping out and newly found ones added, and our detection signals widen over time, so the June to July step is mostly coverage. The line tracks the installed base of the themes and plugins that bundle the file. Since we began tracking it on 16 March 2026, 41,905 domains have dropped it on at least one hostname, and in mid-October 4,393 of those still ran it on another.

"Almost none of these 287,539 domains chose jQuery Mobile. They chose Divi, or a gallery plugin, and the library came along. That's why it outlived its own deprecation." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: the size of this list moves with Divi, not with mobile development. If Elegant Themes drops the file in a future Divi release, the count will fall without a single owner deciding anything.

Who the customers are

67.09% of matched companies with a known size have 1 to 10 employees and 22.29% have 11 to 50. They're established: the 2010s (35.46%) and 2000s (20.15%) lead, and only 12.43% were founded in the 2020s. The industries are local services, led by Construction at 6.02%, and no vertical passes 6.1%. This is the classic agency-built WordPress site.

The enterprise names follow the same pattern at a smaller scale. 1,544 companies have more than 1,000 staff (1,123 at 1,001 to 5,000, 205 at 5,001 to 10,000 and 216 above), and the ones I opened run jQuery Mobile on one WordPress property: Starbucks' and DLA Piper's alumni networks, Fastenal's careers site, Boston Medical Center's jobs site, the University of Chicago's research office. The deliberate users are a small group with older builds: a telecom phone catalogue, a retailer and two university logins on the last stable release, and two more on custom builds.

Sales signal: at large companies the owner is a marketing, alumni or recruiting team running a WordPress microsite. That team buys WordPress care, hosting and design, not developer tools.

Industry and geography

The United States has 59,344 matched companies, but Europe is larger. Germany (18,690), the United Kingdom (16,798), Spain (12,229), France (11,545), the Netherlands (8,818) and Italy (6,915) add up to 74,995. The top three match our Divi profile, where Germany and the United Kingdom also follow the US.

Sales signal: European WordPress agencies and hosts serving German, Spanish and French small businesses are the natural channel for any product that sells to this list.

Switching: what the data can and can't say

We publish no switching table here. The two overlaps the data shows aren't switching. 6,607 jQuery Mobile domains also trip our Onsen UI rule today, but that rule matches cookie-consent script names, so the pair measures consent plugins on WordPress sites. Flutter overlaps on 32 domains today (40 ever), small enough to be a handful of companies running a Flutter app beside a WordPress site.

"When a jQuery Mobile site drops it, the cause is usually a theme update or a rebuild, not a decision about mobile frameworks. Track Divi releases, not framework trends." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: the 41,905 domains that dropped it since March are worth a look for rebuild and migration agencies, since some of them rebuilt their sites. Check the live site first, because some closed.

The stack around it

Percentages are of the 282,715 domains with stack data. WordPress is on 94.65%, Divi on 80.42% and jQuery on 100%. jQuery Migrate (94.55%) is WordPress's compatibility layer, jQuery UI shows on 21.25% and Swiper on 14.64%. Google Analytics runs on 54.52% and Google's Site Kit plugin on 13.02%. Elementor is on 4.01%, and that contrast is the cleanest evidence that this list is Divi's, not WordPress's in general.

Sales signal: the gaps are what a set-and-forget WordPress site lacks: performance work, security hardening and analytics beyond Google's free tag. Security scanners already flag the outdated jQuery Mobile file on Divi sites, according to Freshy's guide, which gives a natural opening line.

Key takeaways

• 287,539 domains, but 79.2% of live sampled pages were Divi sites and about 3% served their own copy.
• Deprecated on 7 October 2021; the count follows Divi's installed base, not adoption.
• Small, established businesses: 67.09% at 1 to 10 staff, 12.43% founded in the 2020s.
• Europe outweighs the US: 74,995 matched companies in six European countries against 59,344.
• The 25.91% category share sits on a total inflated by a broken Onsen UI rule.

Sales applications

Outreach template: "Your site at [domain] runs Divi, which loads an outdated jQuery Mobile file that security scanners flag. We help Divi sites clean that up and speed up. Worth a 15-minute look?"

Targeting: filter jQuery Mobile domains for Germany, the United Kingdom or Spain and 1 to 50 employees, then exclude the domains without Divi to get a clean Divi small-business list.

Competitive angle: for page-builder and theme vendors, this is a list of Divi sites with an old dependency; a migration offer that removes it has a concrete hook.
