Companies Using Chart.js

With 10+ years in web crawling and technographic data analysis, I have examined Chart.js adoption patterns across 50M+ domains and 40K+ technologies. This analysis covers 303,679 active domains and the 213,015 companies we could enrich from them, a 70.1% match rate, as of our August 2026 crawl. The short version: Chart.js is the most deployed charting library on the web by an enormous margin, and most of that deployment was never a decision anyone made. All external claims are linked to their original sources.

1. Scale and trajectory

Chart.js is on 303,679 active domains, up from 248,870 in June 2026 across our current crawl window. Total detected domains, active and dormant, reached 329,097. Only 28,295 domains have dropped the library since we began tracking in March 2026, so attrition is small relative to the base. Some of the month-on-month movement reflects the domain set we crawl turning over between months, so the trend line is more reliable than any single step.

The open-source project itself is healthy. GitHub shows 67,400+ stars, 11,900+ forks and 117 releases through v4.5.1 in October 2025 (GitHub). The official documentation cites roughly 2.4 million weekly npm downloads (Chart.js docs). Those are the metrics of a mature, widely adopted tool.

"Three hundred thousand domains is a reach number, not an adoption number. Most of the sites we detect Chart.js on installed a theme, not a charting library." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: Treat the raw count as top-of-funnel reach and qualify hard. The buyers who can act on a charting pitch are the minority of this base who wrote the integration themselves.

2. Chart.js is a WordPress technology

This is the finding that reframes everything else. 96.65% of Chart.js domains also run jQuery. 75.09% run WordPress. jQuery Migrate is on 74.28%, jQuery UI on 55.79%, Masonry on 55.5%, Font Awesome on 52.38%, Isotope on 51.63%, Bootstrap on 45.18%, Contact Form 7 on 38.63% and Slider Revolution on 31.11%. Masonry, Isotope, Slider Revolution and Contact Form 7 together are the signature of commercial WordPress themes, the ones sold with a demo importer and forty bundled plugins. Chart.js is in that bundle.

The obvious objection is that WordPress is on a third of the web, so any large technology will look WordPress-heavy. That objection does not survive the reverse check. Chart.js is on only 2.41% of the 9,907,845 WordPress domains we detect, but 75.09% of Chart.js domains are WordPress. Against a corpus where WordPress is roughly a third of all domains, Chart.js is about 2.3 times over-indexed on WordPress. The concentration is real, and it is not an artefact of WordPress's size.

Sales Signal: The distribution channel for anything that competes with or extends Chart.js in this segment is the WordPress plugin directory and the theme marketplaces, not developer relations. A plugin that swaps the rendering layer reaches more of this base than any amount of npm marketing.

3. Customer profile: a small-business mass with an enterprise head

62.19% of matched companies have 1-10 employees and 85.89% have fewer than 50. Only 611 companies, 0.31%, sit in the 10001+ bracket. Yet the 50 most-followed organisations we detect are almost entirely enterprises: IBM, Tech Mahindra, Kotak Mahindra, Koç Group, AECOM, 3M, Baker Hughes, CEVA Logistics, Compass Group, Broadcom, UniCredit, Deere, Emerson, Siemens Healthineers, ADNOC, Lenovo, China Mobile and Arcadis among them.

Those two facts are not in conflict once you look at the detection URLs. IBM appears on community.ibm.com, 3M on investors.3m.com, Deere on dealerlocator.deere.com, Emerson on ir.emerson.com, Broadcom on community.broadcom.com, Synopsys on training.synopsys.com. For a large organisation a Chart.js detection is almost always one microsite, one investor relations page or one community forum, not a company-wide standard. Counting domains overstates how deeply any of these companies have adopted the library.

The age distribution is odd for a JavaScript library released in 2013. 39.86% of matched companies were founded in the 2010s, but 19.11% date from the 2000s, 10.29% from the 1990s, 5.58% from the 1980s and 10.24% predate 1980. More than a quarter of this base was founded before the year 2000. That is what happens when a library spreads through website refreshes rather than through engineering teams.

Wikipedia notes that Chart.js was created by London-based web developer Nick Downie in 2013 and is now community-maintained (Wikipedia). The MIT licence and zero cost made it the default starting point for JavaScript charting, and the theme ecosystem did the rest.

Sales Signal: Two playbooks, and they share almost nothing. For the micro-business majority, sell through the agency or the theme vendor. For the enterprise head, the buyer is a single team that owns one property, so expect small deals and short cycles rather than platform-wide agreements.

4. Industry and geography

The industry table is the second surprise. Real Estate leads at 8,627 matched companies (4.73%), then Construction (7,504, 4.11%), IT Services and IT Consulting (6,888, 3.78%), Business Consulting and Services (6,091, 3.34%), Advertising Services (5,493, 3.01%) and Financial Services (5,161, 2.83%). Software Development is seventh at 4,738 (2.60%). A charting library whose seventh-largest vertical is software is not being adopted by developers; it is being installed by whoever built the site.

Geographically Chart.js is unusually well spread. The United States leads with 45,822 domains, but Germany (15,387), the United Kingdom (12,942), Spain (11,596), Italy (10,806), India (9,930), France (9,361) and Brazil (9,248) follow closely. Most technologies we track show a much steeper drop after the United States. Chart.js does not, because it costs nothing, requires no contract and travels wherever WordPress themes travel. There is no sales motion to concentrate it in English-speaking markets.

Sales Signal: Southern Europe and Latin America are proportionally larger here than in almost any commercial tool. Spanish, Italian and Portuguese documentation and community presence would reach a genuinely underserved share of this base.

5. Migration patterns

Migration between charting libraries is remarkably quiet. Chart.js gained 70 domains from D3, 48 from ApexCharts.js, 45 from Highcharts, 24 from Google Charts, 22 from CanvasJS and 14 from amCharts. It lost 54 to ApexCharts.js, 47 to Highcharts, 29 to D3, 15 to Recharts, 14 to amCharts and 9 to ECharts. Net across those corridors is about +55 domains on a base of 303,679, which is statistical noise.

The shape is more informative than the magnitude, and it splits by generation. Chart.js wins against the older cohort: 2.4 domains taken from D3 for every one lost, and roughly six from Google Charts for each one going the other way. It loses to the React-era libraries: Recharts runs about three to one against it, and ApexCharts.js is slightly ahead on the exchange. Nobody is leaving Chart.js at scale. New React and Vue applications are simply starting somewhere else.

Sales Signal: Do not build a campaign around Chart.js churn; there is not enough of it to fund one. The opportunity is greenfield React and Vue projects that would once have defaulted to Chart.js, where Recharts and ApexCharts.js are already winning.

6. What the reviews add

G2 reviewers give Chart.js 4.4 out of 5 stars across 123 reviews (G2). The praise is consistent: ease of implementation, a responsive API, quick setup. So is the criticism: performance drops on large datasets, and there is no 3D or geospatial support. Chart.js renders to HTML5 canvas, which Wikipedia describes as "considered significantly easier to use though less customizable" than D3 (Wikipedia). That trade is the whole product. It is also why the tiny minority of teams with hard performance or chart-type requirements are the ones who ever leave.

Sales Signal: Dataset size and missing chart types are the only two complaints that reliably precede a switch. Prospects raising either are worth pursuing; prospects praising ease of setup are not going anywhere.

7. Key takeaways

1. Market position: #1 of 55 in Charting & Data Visualization with 68.67% share and 303,679 active domains, roughly thirteen times Highcharts.

2. What the number means: reach, not adoption. 75.09% of these domains run WordPress and 96.65% run jQuery, so most detections came bundled in a theme.

3. Core customer: 62.19% have 1-10 employees, concentrated in real estate, construction and consulting rather than software.

4. Enterprise footprint: real but shallow. 611 companies in the 10001+ bracket, and their detections sit on community forums, investor pages and dealer locators.

5. Competitive risk: not churn (net +55 across the visible corridors) but substitution at the point of new project creation, where Recharts and ApexCharts.js are taking React-era work.

8. Sales applications

Outreach template: "Hi [Name], I noticed [Company] runs Chart.js on [subdomain]. Most teams we speak to inherited it with a theme and never revisited it. Worth ten minutes to see what it is costing you on render time?"

Targeting strategy: On TechnologyChecker.io, filter for Chart.js plus company size 51-200 plus Software Development or IT Services. That intersection is small against the full base, but it is where the library was chosen rather than inherited.

Competitive angle: For the WordPress mass, compete on the plugin shelf. For the React-era greenfield, compete on framework-native ergonomics, which is exactly where Recharts is already beating Chart.js three to one.
