Companies Using Video.js

I expected the Video.js list to be media companies and product teams that chose an open-source player. They're in it, but they're the minority, and getting to them took a correction. Our crawl first matched Video.js on 777,498 live domains, because the rule also counts stylesheets that name its classes. When I opened 70 of those at random in a browser, 62 loaded and only 13 ran the Video.js script; 47 carried its stylesheet and nothing else. So this page counts the 222,177 domains where the player script runs, as of our October 2026 crawl, 135,802 of them matched to a company.

Weebly is two thirds of it

Weebly runs on 67.79% of the domains in this count. Its page script loads an old Video.js build, one that reports no version, along with MediaElement.js 2.9.5, on pages with or without a video. 11 of the 12 Weebly pages in my sample ran it, and two of them showed a player. Square Online sites, which we almost always detect as Weebly too, are 14.75%. WordPress (8.85%) and ClickFunnels (5.85%) follow, and the rest are sites where our crawl read a version from the running script.

Sales signal: a Weebly domain in this list is a Weebly customer first. If you sell video tools, filter Weebly out and work the versioned sites.

What we left out

Duda is the largest group we removed. Its runtime stylesheet included Video.js class names on every Duda site I loaded, and its runtime script fetches Video.js 5.11 from Video.js's CDN only when a page contains a Duda video widget. In the 40 days to mid-October, 312 of the 188,365 Duda domains we read reported a running version, and only those stay in. HighLevel's Video element, Moodle themes and slider plugins leave the same stylesheet-only trace.

Sales signal: stylesheet-only sites aren't Video.js users, but they are builder customers who could switch on a video widget. That's a Duda or HighLevel conversation, not a Video.js one.

Versions in use

The script reports its version, which is the clearest sign it ran. In the 40 days to mid-October, our crawl read one on 58,509 domains. 7.x leads with 21,316 and 8.x has 20,446, ahead of 5.x (9,039), 4.x (4,395) and 6.x (3,278). None reports 10.x yet.

Sales signal: the 16,712 domains on versions 4 to 6 run builds several major releases old. For a video platform or an agency, that's a concrete upgrade list.

Growth trajectory

There's one point on the chart: 222,177 domains in October 2026. The running-player test uses version readings from the last 45 days, so earlier months can't be rebuilt on the same basis, and I'd rather show one honest point than a line that mixes two definitions. Exits are counted on the wider basis: since March 2026, 121,824 domains dropped a Video.js signal on at least one hostname, stylesheet-only domains included, and about 13.5% of those still carry it on another. Later points won't be a same-domain comparison either, because the set of domains we crawl turns over every month, with dead sites dropping out and new ones added, and our detection widens over time.

"Three in four Video.js pages I opened carried its stylesheet and nothing else. Counting only running players cut the number by more than two thirds, and the page is more useful for it." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: track this count by version, not by total. A rising 8.x share means sites are upgrading; a rising Weebly share says nothing about video.

Who the customers are

75.35% of matched companies with a known size have 1 to 10 employees, and only 1.14% (1,393) have more than 1,000. The large ones take two routes. Some host the library: IBM's community site loads 7.21.6 from cdnjs, Disney's careers site 8.21.1 from Video.js's CDN, Wipro 8.21.1 inside its own site code and Reliance Industries 7.20.3. Others get it inside Brightcove Player, which uses Video.js as its underlying player framework: Boeing (8.24.1), Cisco (8.23.4), Mary Kay (7.21.4) and Siemens's press site (8.23.0).

Sales signal: at a large account, a Brightcove script next to the player means an existing video platform contract. A self-hosted build means an in-house team owns playback, and that's who you talk to.

Industry and geography

Medical Practices leads at 5.2%, then Retail (3.94%), Construction (3.8%) and Individual and Family Services (3.28%), with Non-profit Organizations (2.46%) and Restaurants (2.44%) in the top ten. The United States has 76,667 matched companies, 64.3% of the 119,273 in the top 15 countries, ahead of the United Kingdom (10,256), Canada (7,423) and Australia (6,150). MediaElement.js, which WordPress carries, has a flatter map: the US holds 36.9% of its top 15.

Sales signal: the small-business end of this list is English-speaking clinics, shops and restaurants, mostly on Weebly. Pitch them on the website, not the player.

Overlap with other players

There's no migration table, because no rival passes our switching tests. MediaElement.js overlaps most, and for a mechanical reason: Weebly's page script loads both libraries, so two thirds of this count runs MediaElement.js 2.9.5 as well. YouTube embeds, Plyr, JW Player and Flowplayer also appear beside Video.js, and most domains that ever ran one of them with Video.js still run both.

"Video.js and Plyr show up as rivals in every comparison post. Since October 2025, Plyr's creator has been designing the skins for Video.js 10." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: a site running Video.js beside YouTube embeds may be splitting its video between self-hosted files and YouTube. Ask which one it would keep.

The stack around it

Across the 222,177 live domains in our stack analysis, Cloudflare's CDN runs on 75.77%, Google Analytics on 64.41% and Snowplow Analytics on 62.84%, the last because Weebly's pages load it. Lodash (62.91%) and Underscore.js (62.87%) sit at almost the same share as each other. jQuery is on 82.17%, and Matomo reaches only 1.64%.

Sales signal: analytics tags here say more about Weebly than about the business. Use Matomo, or the absence of Weebly, as a filter for sites that chose their own stack.

Video.js today

Video.js is free under the Apache 2.0 licence. Brightcove led the project until 2025, when Mux took over as steward, according to videojs.org. Mux was founded by Steve Heffernan, who created Video.js, and the VIDEO.JS name is still a Brightcove trademark. In October 2025 Mux announced Video.js 10, a rewrite built with the people behind Plyr, Vidstack and Media Chrome, and the GitHub repository now lists v10 as stable. None of the domains reporting a version in our crawl runs 10.x yet.

Sales signal: v10 is a ground-up rewrite, so moving a 7.x or 8.x install to it is a migration project, not an update. That's agency work, and a reason for some teams to look at a hosted player instead.

Key takeaways

1. 222,177 live domains where the player runs, 4th of 86 in the category with 6.03%.

2. Weebly sites are 67.79% of them.

3. We left out 555,169 domains whose stylesheets only name Video.js classes, Duda the largest group.

4. 58,509 domains reported a running version, mostly 7.x and 8.x.

5. Large companies run it themselves or inside Brightcove Player.
