Companies Using Swiper

Swiper is the library nobody mentions in a pitch deck and millions of websites ship. Our October 2026 crawl finds it on 4,380,045 live domains, and 2,550,722 of them match a company record, a 58.2% match rate. It ranks 5th in JavaScript Libraries with 4.98%. Swiper is free under the MIT licence, with Vladimir Kharlampidi named in its licence file, so these are sites, not customers. For a seller, the question isn't who chose Swiper. It's who built the site, because on many of these domains the choice came with a page builder, theme or plugin.

What we count

A page counts when it has Swiper's slide markup, defines the Swiper global or loads a script named swiper.js or swiper.min.js. Two things follow. First, a site can count without showing a carousel: in a random sample of 80 Swiper pages we opened in October 2026, 59 rendered a slider and 21 loaded the library with none on the page we saw. Second, the file-name test also matches Tiny-Swiper, a separate library that GoDaddy's CoBlocks plugin loads as tiny-swiper.js. CoBlocks appears on 1.07% of Swiper domains, which caps that error at about one in a hundred. Our guide to technology detection methods covers how markup and script signals differ.

Elementor is the distribution channel

WordPress runs on 65.96% of the 4,331,092 domains in our clean live set, and Elementor on 42.62%. Elementor's developers explain why. In 2019, its 2.7 release moved the Image Carousel and Slides widgets from Slick to Swiper. The 3.26 update calls Swiper "a JS-based library used by Elementor to create a slider / carousel", says older versions loaded its stylesheet on every page, and finished moving all Elementor widgets to Swiper 8. In our sample, 34 of the 80 Swiper pages ran Elementor and 28 served Elementor's own bundled copy from its plugin folder. That copy is the real library, so these are real Swiper sites. Their owners didn't pick it; Elementor did. Counting themes, plugins and Shopify stores too, 44 of the 80 sampled pages got Swiper from a builder or add-on. Old Elementor builds leave old copies behind: one Swedish property firm still loaded Swiper 5.3.6 from Elementor with no carousel on the page.

Sales signal: on a WordPress site, a Swiper detection is about two times in three an Elementor detection (42.62% against 65.96%). WordPress agencies, Elementor add-on makers and hosting companies get more from this list than JavaScript tooling vendors do.

Growth, read carefully

The chart reads 3,360,806 domains in June, 4,027,609 in July, 4,101,364 in August, 4,319,947 in September and 4,380,045 in October. I wouldn't present the July step of 666,803 as adoption. The set of domains we crawl turns over every month, with dead sites dropping out and new ones coming in, and our detection signals widen over time; both moved the line. Exits are large too. 550,496 domains have dropped Swiper on at least one hostname since 16 March 2026, about 12.6% of today's count, and roughly one in ten of those still runs it on another hostname. A library that rides on site templates comes and goes with redesigns.

"Swiper's reach is mostly borrowed. Elementor and the WordPress themes around it decided for millions of sites, so I'd sell to the people who build those sites, not the people who own them." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: size the market at about 4.4 million domains and expect heavy turnover. No rival slider passes our switching tests, so a domain that drops Swiper is more likely redesigned or switched off than converted, which makes it a lead for site builders.

Who the companies are

59.57% of matched companies with a size band have 1 to 10 employees and 84.31% have 50 or fewer. 57.94% were founded in 2010 or later. The 33,950 companies above 1,000 staff use Swiper on specific surfaces. Accenture loads Swiper 11.2.10 from jsDelivr on its investor site. Johnson & Johnson, ADP and Cognizant load Swiper 11.0.5 from cdnjs on their careers sites, and Concentrix runs its careers site on Elementor. Boeing, Huawei and HDFC Bank show it on their home pages, and Orange's wholesale site still serves Swiper 4.5.1, released in September 2019.

Sales signal: at a large account the Swiper owner is whoever runs one site, often a careers or investor-relations team working with an agency. A Swiper file ten major versions behind, as on Orange Wholesale, marks a site nobody has rebuilt in years.

Where it's used

The United States has 513,655 matched companies, 20.1% of the total. Germany (170,707), the United Kingdom (167,884), Brazil (159,582) and India (151,345) follow, and the four big English-speaking markets hold only 32.8% together. Industries are spread thin: Construction leads at 4.37%, then Retail (4.14%), IT Services (3.75%) and Business Consulting (3.18%), and the top ten add up to 28.9%. Trade firms in our sample, from a German carpentry business to a water-damage restoration company, ran Elementor carousels.

Sales signal: local-services marketing (reviews, booking, lead capture) fits this base better than developer tooling. Germany and Brazil are big enough to deserve their own campaigns.

Next to the other sliders

No switching pair passes our tests. Sites stack sliders: 395,192 domains run Swiper and Slick together today, and 78% of the 506,909 ever seen with both still have both. OWL Carousel and Flickity both hold at 80.4%. Slick is moving again, with 2.0.0 released on 13 September 2026 after 1.9.0 in April 2018, but on our data it mostly sits on the same sites as Swiper rather than replacing it.

"Close to 400,000 sites load Swiper and Slick together. Few teams chose two slider libraries on purpose; they collected them, one theme or plugin at a time." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: page-speed and performance vendors have a concrete pitch for sites that load two or three slider libraries. Filter for Swiper plus Slick or OWL Carousel and lead with the duplicate weight.

The stack around it

jQuery runs on 83.45% of Swiper domains, core-js on 63.25%, jQuery Migrate on 57.61% and jQuery UI on 46.49%. Bootstrap appears on 25.2% and Tailwind CSS on 10.41%. GSAP is on 18.93% and Masonry on 17.76%. Hosting leans to shared WordPress hosts, with GoDaddy on 12.14% and Hostinger on 8.43%, and some sites load Swiper from a public CDN such as jsDelivr.

Sales signal: a jQuery-heavy stack marks WordPress sites rather than modern app builds. Hosting upsells, maintenance plans and rebuild agencies will find more of their buyers here than front-end framework vendors will.

Key takeaways

1. 4,380,045 live domains, 5th in JavaScript Libraries, and the largest carousel library we track.

2. Free and MIT-licensed. The paid products are Swiper Studio, from $8 a month, and premium plugins.

3. WordPress on 65.96% and Elementor on 42.62%: on a large share of these sites a page builder, theme or plugin chose Swiper.

4. Small, young, global: 59.57% with 1 to 10 staff, and only 32.8% in the four big English-speaking markets.

5. Sliders stack rather than replace each other.

How to use this list

Split the list by Elementor first. Elementor rows are leads for WordPress agencies, add-on makers and hosts; the rest, especially sites that bundle Swiper or load it from a CDN, are more often custom front ends. A workable opener for the first group: "Your site's carousel runs on Elementor's copy of Swiper. Here's how [product] makes that page faster without a rebuild."
