The short answer: a creative studio for the campaign, a product studio for the configurator, a platform for the catalog

For a launch site or brand experience, shortlist Active Theory, Little Workshop, makemepulse and Noomo. For a configurator or 3D product page that has to talk to an ERP, a pricing engine or a checkout, look at darkroom.engineering, MetaDesign Solutions and the Culver City studio at number four. For hundreds of configurable SKUs, or for CAD and geospatial data, a platform such as Threekit, Zea or Cesium usually beats custom code. Most engagements land in the $10,000–$49,000 band Clutch reports as the typical software project (Clutch pricing guide, data updated September 2026).

How this list was built: fit to the job first, headcount last

Every company was checked on its own website, and its Clutch profile where one exists, on September 20, 2026. To qualify, a vendor had to show publicly a named WebGL, Three.js or React Three Fiber project, a published stack, or a product that renders in the browser. Art-outsourcing shops that do not ship to the web were left out.

The order follows fit to three buyer jobs: brand experiences, product configurators and viewers, and CAD or data visualization. It is not a ranking by size or review count. Deliberately ignored: award tallies, logo walls without case studies, and vendor-reported results without a baseline. Where a company does not publish a budget, timeline or headcount, the table says "not published". Nothing is estimated.

Comparison table: company, focus, budget range, timeline and region

The twelve companies, what each does well, and when each is the wrong call

1. Active Theory: brand experiences from Los Angeles with a $25,000 floor

Active Theory has built large-scale WebGL brand experiences since 2012 as an in-house team with its own web toolset. Clutch lists two to nine staff, a $25,000 minimum project and $150–199 per hour (checked September 2026).

Pick them for a campaign or launch site where visual quality and rendering performance decide whether the piece gets shared.

When not to pick them: a team this size is not the natural home for a multi-year product roadmap with ERP integration, and the work page on activetheory.net only renders with JavaScript, so verify projects in a browser first.

2. darkroom.engineering: React Three Fiber inside a real product, with commerce attached

Formerly Studio Freight, darkroom.engineering is a distributed design and development studio across Spain, Italy, France, Argentina and the USA. Its published stack is specific: WebGL, Three.js, React Three Fiber, Lenis, Next.js and GSAP, with Sanity, Contentful and HubSpot for content, plus headless commerce. Named projects include Ibicash, Framer and the Bad Omens site.

Pick them when the 3D scene has to live inside a React or Next.js application with a CMS and a checkout, not as a microsite someone rebuilds next year.

When not to pick them: no pricing, founding date or headcount is published, so the first call is about budget fit, and with five countries involved, ask which time zone owns delivery.

3. Little Workshop: real-time 3D for the browser and the trade-show floor

Little Workshop, founded in Paris in 2010, makes real-time 3D experiences for all platforms and lists WebGL, Unity and Unreal Engine as its stack. Named projects include Netlify's "5 Million Devs", Equinox and Paramount Studios.

Pick them when the same 3D content must exist as a web experience and as an installation, kiosk or app, so one studio owns the canonical asset.

When not to pick them: no pricing, timeline or team size is published, and the portfolio is experience-led, so a configurator with pricing rules and an order handoff sits outside the published profile.

4. A Culver City studio founded in 2020 that publishes its brackets and timelines

Todor3D positions itself around 3D configurator development and immersive web work, with WebGL, Three.js, React Three Fiber and WebAR/WebXR as the stack and three practice areas: 3D & Immersive, Custom Software Engineering and AI Solutions. Founded in 2020, the studio reports 40+ engineers across three continents, 300+ delivered projects and 25 Clutch reviews at 5.0, and publishes brackets of $10,000–50,000, $50,000–100,000 and $100,000–250,000+, with timelines of 4–10 weeks, 3–6 months and 4–12 months. The homepage lists a closet configurator ($10K–50K bracket, four months) and a jewelry configurator in the same bracket.

Pick the team when you need a configurator with a fixed budget and a published timeline, and want the backend, pricing logic and integration from one vendor.

When not to pick them: founded 2020, so the track record is shorter than the 2005–2012 vendors here. For a purely art-directed campaign site, a creative studio's portfolio will matter more than an engineering bench.

5. makemepulse: consumer brand experiences and retail games on Three.js

makemepulse works from Paris and London across immersive web, mobile games and e-commerce, and sponsors Three.js Conf Paris. Case studies include an AI shopping experience for Brunello Cucinelli, "Benno's Light" for the Claims Conference and the Rösti Fall loyalty game for McDonald's France.

Pick them when the audience is consumers and the goal is engagement or loyalty; the Cucinelli case shows they can carry that into retail.

When not to pick them: pricing, timelines and team size are not published, and the portfolio is campaign-driven, so for a permanent product tool ask who maintains the code afterward.

6. Noomo: 3D storytelling sites with published six-figure brackets

Noomo, in Los Angeles with a San Francisco presence, builds 3D storytelling websites and immersive experiences, plus brand video and AI-driven work. The site names Vogue Business, Salesforce and Intel's ai.io as clients. Unusually for a creative agency, it publishes brackets: $50K–100K, $100K–300K and $300K+ (checked September 2026).

Pick them when a US marketing team has a flagship site to launch and a budget that starts in the mid five figures.

When not to pick them: a $20,000 product viewer is below their floor, founding year and team size are not published, and there is no configurator or CAD work on the site.

7. Utsubo: a technology-first studio already shipping WebGPU

Utsubo, in Osaka and Kyoto, calls itself a technology-first creative studio and lists WebGPU, WebGL and Three.js as its stack across web, games and installations. Its blog names BMW, Louis Vuitton, Warner Music, Kia, League of Legends and JR as clients.

Pick them when the brief pushes past a standard Three.js scene, or you want a partner already shipping WebGPU rather than promising to.

When not to pick them: the client list is self-reported on the studio's blog, so ask for full case studies. Pricing and team size are not published, and the Japan time zone constrains a US team expecting same-day answers.

8. MetaDesign Solutions: a 400-engineer offshore bench with a documented Three.js pipeline

MetaDesign Solutions, founded in 2006 in Gurugram with offices in Brisbane and Detroit, is a general software firm with a dedicated Three.js practice: configurators, architectural visualization, WebXR and 3D data visualization, claiming 20+ shipped Three.js projects. It calls React Three Fiber its default and publishes a full asset pipeline: Drei, Zustand, glTF, DRACO, KTX2, GLSL and Rapier physics.

Pick them when the budget is tight, the scope is large and you want a US-hours contact in Detroit in front of an offshore team.

When not to pick them: the Three.js case studies are anonymized ("Premium Furniture Brand", "Architecture Firm"), so the 3D work cannot be verified from the site.

9. Supermarket: an R3F studio with a prototyping tier before you commit

Supermarket Design, in Dartington, Devon, builds all its 3D work in React Three Fiber, alongside Next.js, Prismic and GSAP. Named projects include the Agglayer Visualizer for Polygon, Zeek's Zoo for Matter Labs and Fleetbuilder for Highland; the client list adds Meta, Lululemon, Bupa and Google. It offers starter sites, custom builds, retainers and "mini builds" for prototyping.

Pick them when an idea needs a proof of concept before a full budget is released, or when you want a retainer rather than a one-off.

When not to pick them: the site promises affordable prices but publishes no figures, and team size is not stated, so several parallel workstreams may exceed what they can staff.

10. Threekit: the platform route for hundreds of configurable SKUs

Threekit, founded in 2005 and headquartered in Chicago with offices in London, Ottawa, Paris and San Francisco, is a visual commerce platform rather than a studio: 3D configurator, AR and an AI guided-selling agent integrated with CPQ, ERP and commerce systems. Case studies cover Andersen Windows & Doors, Sloan and Ulrich Lifestyle Structures; the company reports 150+ manufacturers live and 4× faster quoting at Sloan (Threekit's own data, 2026, no baseline).

Pick them when the catalog has hundreds of configurable products, a CPQ already exists and you need rendering at scale.

When not to pick them: it is a license, not a one-time build, so model the multi-year cost; for a single flagship product, the platform is more than the job needs.

11. Zea Inc: native CAD data turned into configurators and parts catalogs

Zea, in Montreal, runs on its own WebGL engine and turns CAD and business data into interactive digital twins for production, sales, documentation and after-sales. Products include configurators, parts catalogs, technical illustrations, the SimStream CAE visualizer and Zea Cortex; success stories name Trebro, Motrec and Taiga Motors.

Pick them when the source of truth is engineering CAD and one model has to serve sales, service manuals and spare-parts ordering.

When not to pick them: this is a platform for industrial data, not a creative studio, and pricing is not published.

12. Cesium: the open standard when the subject is a city, a site or the planet

Cesium GS, in Philadelphia, maintains CesiumJS, the OGC-adopted 3D Tiles standard, the Cesium ion hosting service and Cesium for Unreal. Recent blog posts cover the Hopeworks Camden digital twin (August 2026) and a technology hub opened with Bentley Systems (September 2026). The same blog published the compression benchmark WebGL teams still quote: the Khronos "Buggy" model went from 7.6 MB to 0.82 MB with Draco (Cesium, 2018).

Pick it when the data is geospatial: terrain, buildings, infrastructure, photogrammetry. A free Cesium ion community account is enough to prototype.

When not to pick it: Cesium is a library and platform, so you still need a developer, possibly one of the studios above, to build the application, and product configurators are outside its scope.

How to choose for your own project: six questions that separate a demo from a pipeline

Every studio here can make a beautiful scene. The differences show up on a mid-range phone, in the month after launch, and when the catalog changes.

1. Who owns the source code and the 3D assets at the end? Platforms license; studios should transfer, including editable model files, not only the exported glTF.
2. What is the file budget per scene, and what compression do you use? The median web page already weighs 2,652 KB on desktop (HTTP Archive Web Almanac, 2024); one uncompressed model can match that. A vendor that names Draco and KTX2 unprompted has done this before.
3. What is the performance target on a phone, and how do you measure it? Renault found every one-second improvement in Largest Contentful Paint raised conversion 13% across 10 million visits (web.dev case study, 2021 data). Ask for a device list.
4. How does the scene connect to our pricing, ERP or PIM? A configurator that cannot read option rules from the system that holds them will be wrong within a quarter.
5. What does maintenance cost, and who does it? Agencies surveyed by GoodFirms budget 15–25% of build cost per year (GoodFirms app cost survey, 2026). If the vendor has no answer, you are the answer.
6. Show a project whose brief looked like ours, with the client named. Several studios here list clients without case studies. A named project with a description of what was built is the minimum.

FAQ: what buyers ask before hiring a WebGL company

What does a WebGL development company actually do?

It builds interactive 3D that runs in a browser without a plugin or download: product configurators, 3D viewers, brand experiences, digital twins and data visualizations. Most use Three.js or React Three Fiber on top of WebGL, and increasingly WebGPU, and the work spans modeling, front-end engineering and integration with commerce, CPQ or CAD systems.

How much does WebGL development cost?

Published figures on this list run from $10,000 to $300,000 and up: the Culver City studio at number four publishes brackets from $10,000–50,000 to $100,000–250,000+, Noomo starts at $50K and Active Theory's Clutch minimum is $25,000. Clutch reports $10,000–$49,000 as the typical software project and an average total of $132,480 (Clutch pricing guide, 2026). Platforms such as Threekit price as licenses and do not publish figures.

How long does a WebGL project take?

Only one company on this list publishes timelines: 4–10 weeks for a first-bracket project, 3–6 months for a mid-size build and 4–12 months for the largest. Everyone else quotes per project. Asset work sets the schedule more than code does, so ask how many models are in scope and what you can supply.

Should I hire a studio or license a 3D platform?

License a platform when many products share a structure, a CPQ or ERP already exists and you have a team to manage content; Threekit, Zea and Cesium are the platforms here. Hire a studio when the experience is unique, the product count is small, or you want to own the code. GoodFirms puts senior developers at $110–200+ per hour in the US, $40–100+ in Eastern Europe and $30–70 in India (survey of 267 app companies, August 2026).

Does 3D on a product page change sales?

The evidence is vendor-reported but consistent in direction. Shopify's case data for Rebecca Minkoff showed shoppers who viewed a 3D model were 44% more likely to add to cart and 27% more likely to order, and AR users were 65% more likely to purchase (Shopify, 2020–2021 cohort, single brand). Treat those as an upper bound and measure your own add-to-cart rate before and after launch.
