Companies Using ECharts

I work on how TechnologyChecker.io's data gets used in campaigns, and ECharts is a page where the list and the base tell two different stories. As of our October 2026 crawl, we find Apache ECharts on 4,689 live domains, and 2,039 of them match a company record, a 43.5% match rate. ECharts is free under the Apache License 2.0 (the project's FAQ says so directly), so these are sites, not accounts. A domain counts when a page loads an ECharts build, including from jsDelivr, or renders a chart container ECharts has marked. Copies bundled into an app under another name, and anything behind a login, are missed, so treat the count as a floor. Our detection methods post covers how signals like these are matched.

Growth trajectory

The chart reads 2,247 domains in June 2026, 3,733 in July, 4,284 in August, 4,566 in September and 4,689 in October. Most of that rise came in one step, June to July. Counts are not a like-for-like series over time: 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. That step reflects changes on our side, both the domains we cover and the signals we detect ECharts with, rather than a surge in adoption. Since August the line has flattened, adding 123 domains between September and October.

On exits, 737 domains lost ECharts on at least one hostname since we began tracking it on 16 March 2026. When we re-checked on 12 October, about 85 of those still showed it on another hostname.

"ECharts arrives with whoever builds the site, and on this list that's often an investor-relations agency rather than the company's own developers. Find the builder and you've found the buyer." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales Signal: Plan on the October count and don't read the June to July jump as a buying window. A domain that first appears in our data isn't necessarily a new build.

A footprint that leans Chinese

ECharts started at Baidu in 2013 and became a top-level Apache project in January 2021, according to the ASF. The base still shows that origin. China leads our matched companies with 467, about 1.8 times the United States (266), and Baidu Analytics runs on 12.35% of live ECharts domains, with CNZZ (1.86%) and 51.LA (1.4%) as well. Domain names undersell it: only 291 of 4,852 live domains end in .cn, because firms such as iQiyi (ec.iqiyi.com), LY.com (flights.ly.com) and Zhaopin use .com addresses. Thailand is third with 84 matched companies, India fourth with 81.

Sales Signal: If you sell into Chinese web teams, ECharts plus Baidu Analytics is a cleaner filter than the .cn suffix. If you don't, exclude Baidu Analytics sites before you build a Western campaign, or about one site in eight will be the wrong market.

Who the companies are

This base is older and larger than Recharts'. 40.34% of matched companies with a size band have 1 to 10 employees, but 147 companies, 8.35%, have more than 1,000, against 0.98% on Recharts. The 2010s are the largest founding decade at 39.24%, and 19.23% were founded before 2000. Industries spread thinly: Software Development leads at 9.88% and the top ten add up to 46.07%, with Higher Education (2.27%) and Environmental Services (1.62%) inside it.

The verified names show where large organisations use it. Semrush draws its AI Visibility Index with ECharts, Netskope its trust portal's maintenance timelines, the Apache Software Foundation its own projects directory, and Statistics South Africa its census charts.

Sales Signal: In our list, ECharts at a large company marks a data-heavy public page: a statistics portal, a public index, an investor site. Pitch data-visualisation services, reporting platforms and accessibility audits to the team that owns that page, not to central IT.

The investor-relations layer

Seventeen of the 50 companies in our named list carry ECharts on an investor-relations, annual-report or sustainability site. For 14 of those 17, the library came with a supplier's platform or template. Seven of the Thai investor sites we opened are served through ShareInvestor Thailand's listedcompany.com platform. Asmodee's and Protector Forsikring's investor sites load an ECharts build from Odin IR, a share-widget provider, and so does BW Offshore's website. PRIO's investor site loads an ECharts chart engine from MZiQ's stock viewer. Four Dutch annual reports, Arcadis, BAM, Van Oord and Unica, load ECharts 5.5.0 from the same file path, which points to one reporting template.

Keep that in proportion. Across the whole base, only 68 of 4,852 live domains carried ECharts on an investor-relations hostname and 14 on an annual-report or sustainability one in the same 12 October check. Ranking by LinkedIn following lifts listed companies to the top of the list.

Sales Signal: For IR-site agencies and reporting-software vendors, the chart library identifies the incumbent supplier. A listedcompany.com or Odin IR footprint tells you who built the site before you call the investor-relations team.

Why this profile has no migration table

Every charting corridor failed our checks. The libraries share sites far more than they replace each other: 493 live ECharts domains also run Chart.js, 284 run ApexCharts.js, 111 run D3 and 62 run Highcharts. The one row that looked like a flow, 30 domains dropping Highcharts while keeping ECharts against 6 the other way, turned out to be led by one supplier. In a sample of 12 we opened, 10 were company sites using Odin IR's investor widgets, and the drops cluster on 4 and 5 July 2026 for five of them. That looks like a vendor changing its chart engine, not customers choosing a library.

"Thirty domains leaving Highcharts sounds like a story until you open them and find the same investor-site widget on ten. That's one supplier's release, and we won't dress it up as a market shift." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales Signal: Don't run a "switch from Highcharts" campaign off this data. If you sell a charting product, the opportunity is with the platforms that embed one library across hundreds of client sites.

The stack around ECharts

Across the 4,844 live domains in our clean set, jQuery runs on 59.81%, core-js on 54.21%, Swiper on 43.87% and Bootstrap on 38.58%. Tailwind CSS reads 25.58%. Vue.js is the leading framework at 16.8%, often with Element UI (11.02%) and sometimes Layui (4.42%), another Chinese UI kit. Next.js reads 10.28%, React 5.76% and Angular 3.36%. On the server, Microsoft ASP.NET (6.63%) and Ruby on Rails (6.11%) lead. Google Analytics runs on 38.79%.

Sales Signal: Pitch modernisation carefully. A jQuery and Bootstrap site with ECharts can be a working portal nobody wants to rebuild, and the Vue plus Element UI group is a distinct buyer, worth its own sequence with Chinese-language material.

How to use this list

Start by splitting the list. Filter ECharts plus Baidu Analytics for the China-facing group, and ECharts without it for everyone else. Add a company size of 1,000 or more to reach the enterprise tail, then read the detection URL: an investor. or annualreport. hostname means an agency and the IR team, a main-site chart means an in-house web team.

A workable opener: "I noticed the charts on [page] are built with ECharts. Teams that publish data like that usually [pain point]; here's how [product] helps."
