Companies Using Three.js

With 10+ years in web crawling and technographic data analysis, I've spent hundreds of hours tracking how JavaScript graphics libraries gain and lose traction across the web. Three.js occupies a unique position in our dataset: it's the dominant WebGL library by a wide margin, with 112K GitHub stars, 47,000+ commits (source), and 2.7 million weekly npm downloads (source), yet its 3,483 active domains place it modestly in the broader Charting & Data Visualization category. Below is my analysis of 2,896 enriched companies matched to LinkedIn profiles from our April 2026 crawl.

1. Growth trajectory

Three.js was first released in April 2010 by Ricardo Cabello, but our detection data only picks it up starting March 2016 with 5 domains. That six-year lag reflects how long it took for WebGL to become mainstream in production websites (as opposed to demos and experiments). From those 5 domains, Three.js grew to 3,585 active domains by March 2025, a 717x increase over nine years. The growth curve has been remarkably steady with no plateau: active domains roughly doubled every 18-24 months between 2018 and 2024. The acceleration from 2020 onward (295 domains in January 2020 to 3,585 by March 2025) coincides with the explosion of 3D product configurators, virtual showrooms, and interactive marketing sites that the pandemic triggered.

"Three.js's growth never spiked and crashed like many JavaScript libraries do. It's one of the steadiest adoption curves in our entire dataset, which tells me the use cases are real, not hype-driven." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: The consistent upward trajectory means the addressable market for Three.js services, tooling, and consulting is still expanding. Sales teams targeting creative agencies and product visualization firms should note that Three.js adoption is accelerating, not plateauing. The WebGPU transition (r171, September 2025) made WebGPU production-ready with zero-config imports, and may trigger another growth wave as Safari 26 brought WebGPU to iOS for the first time.

2. Customer profile

The Three.js customer base is overwhelmingly small: 66.5% of companies have 1-10 employees, and 85.3% have fewer than 50. This is a tool for small creative studios, freelance developers, and boutique agencies. The 2010s-founded cohort dominates at 41.42%, with 2020s startups at 18.34%, meaning nearly 60% of Three.js users are digital-native companies less than 15 years old.

The enterprise tail is thin but notable. Ford uses Three.js on ford.com itself, not just a microsite. Bombardier, a $7B+ aerospace company, deploys it across their main domain. Morningstar runs it on their DBRS credit ratings subdomain. These aren't casual experiments: they're production deployments at public companies with rigorous security and performance requirements. The Walt Disney Company's go.com detection and MD Anderson Cancer Center's deployment show Three.js reaching into media, healthcare, and research contexts far beyond its creative-agency core. NASA Glenn Research Center uses Three.js for satellite communication visualization and lunar terrain mapping, while Google maintains an official Three.js overlay library for Google Maps.

Sales Signal: The 66.5% micro-business concentration means pricing and packaging should target freelancers and small studios (sub-$100/mo tools). But the enterprise examples prove that Three.js scales, so a separate enterprise tier for companies needing 3D product visualization, data visualization, or virtual tours is viable. The academic institutions (Tulane, Cambridge University Press, Mancosa) suggest an education/research vertical worth targeting with volume licenses.

3. Industry and geographic concentration

Three.js is genuinely horizontal. No single industry exceeds 5.8%, and the top 10 industries collectively account for just 36.5% of the base. Advertising Services (5.8%) and IT Services (5.69%) lead, but the spread across Real Estate (2.82%), Construction (2.71%), Financial Services (2.29%), and Design Services (2.29%) reflects the breadth of 3D visualization use cases.

Geographically, the US leads at 24% but doesn't dominate the way it does for most SaaS tools (where US share typically exceeds 40%). Europe collectively accounts for over 32% of Three.js adoption, with France (6%), Germany (5.9%), Spain (5.3%), and Italy (5.1%) all showing strong presence. This European strength likely reflects the creative agency and architecture/real estate sectors in those markets, where 3D visualization has been widely adopted for property marketing and product design.

Sales Signal: The European concentration opens a clear go-to-market angle. France, Germany, Spain, and Italy together represent a larger market than the UK for Three.js services. Teams selling 3D configurator platforms, hosting, or managed services should consider European-language support as a differentiator. The real estate and construction verticals (5.5% combined) represent a fast-growing niche where 3D visualization is transitioning from nice-to-have to expected.

4. Migration patterns

Three.js's migration data reveals a library losing users to more specialized tools. The largest outflow is to A-Frame (151 companies lost vs. 31 gained), a 4.9:1 loss ratio. A-Frame is Mozilla's WebXR framework built on top of Three.js itself. So these aren't really losses; they're teams moving up the abstraction stack from raw Three.js to A-Frame's declarative HTML-like syntax for VR/AR content. PIXIjs drew 67 former Three.js users (vs. 10 gained), suggesting some teams decided they needed 2D performance, not full 3D. Highcharts had a more balanced flow: 84 companies moved from Three.js to Highcharts, while 34 went the other direction.

"The A-Frame migration corridor is the most interesting signal. Companies aren't abandoning 3D; they're choosing higher-level abstractions built on Three.js's own foundation." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: The A-Frame outflow represents an opportunity, not a threat. These are teams that still need 3D but want it easier. Tools and services that simplify Three.js (React Three Fiber, Spline, Threlte) are filling this gap. For migration service providers, the Highcharts-to-Three.js corridor (34 companies) represents teams upgrading from 2D charts to 3D. Targeting Highcharts users with "ready for 3D?" messaging could capture this natural upgrade path.

5. Technology ecosystem

The typical Three.js customer runs MonsterInsights (10.4%) for Google Analytics integration, Hotjar (8.12%) for session recording, and Microsoft Clarity (7.05%) for heatmaps. This analytics-heavy stack suggests these websites care about measuring user engagement with their 3D content, not just displaying it.

On the framework side, AngularJS (3.70%) leads over Vue v2 (2.25%), which is surprising given AngularJS's deprecated status. This likely reflects older enterprise deployments that added Three.js to existing Angular apps rather than greenfield React or Vue projects. The styled-components (2.83%) presence signals a React-ecosystem overlap. CMS adoption leans toward Joomla (1.42%) and Drupal (1.04%) rather than WordPress, which is atypical and may reflect the developer-oriented audience preferring platforms with more customization control.

Sales Signal: The AngularJS overlap is a flag: 107 companies are running Three.js on a deprecated framework. These teams need migration support. Any vendor offering Angular-to-React (or Angular-to-Vue) migration services should specifically target Three.js users, since the 3D rendering layer adds complexity to framework migrations. The Hotjar overlap (8.12%) also signals that these companies are actively optimizing their 3D UX, making them receptive to performance monitoring and optimization tooling.

6. Key takeaways

1. Three.js is the undisputed leader in browser-based 3D, with 10x the domain adoption of Babylon.js (314 domains) and 270x the npm downloads (2.7M vs ~10K weekly).

2. Growth remains strong at roughly 40% year-over-year through 2024-2025, with no plateau in sight.

3. The customer base is 85% small teams (under 50 employees), but enterprise deployments at Ford, Bombardier, and Morningstar prove it handles production workloads.

4. Europe accounts for 32%+ of adoption, unusually high for a JavaScript library and driven by creative, real estate, and architecture sectors.

5. The A-Frame migration pattern (4.9:1 loss ratio) signals demand for higher-level 3D abstractions built on top of Three.js.

6. Previously used count of 37,953 sites shows massive experimentation; the 3,483 active deployments are the survivors that found lasting use cases.

7. Sales applications

Outreach template for Three.js agencies: "I noticed [Company] is running Three.js on [detected URL]. Our data shows 66% of Three.js users are small teams. Are you hitting performance or maintenance bottlenecks as your 3D content grows? We help teams like yours with [specific service]."

Targeting strategy on TechnologyChecker.io: filter for Three.js + AngularJS overlap (107 companies needing framework migration), or Three.js + Real Estate industry (74 companies likely building virtual tours).

Competitive angle: companies that recently dropped Three.js for A-Frame (24 in the last year alone) may be struggling with the transition. Reach out with WebXR migration support.
