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

For a brand experience or launch site on Three.js, shortlist Active Theory, makemepulse, LUSION and Noomo. For a configurator or 3D feature inside a React product with a checkout or ERP behind it, look at darkroom.engineering, basement.studio, MetaDesign Solutions and the Culver City studio at number four. For hundreds of configurable SKUs, Threekit's platform usually costs less than custom code. Most engagements land in the $10,000–$49,000 band Clutch reports as typical for a software project (Clutch pricing guide, September 2026).

How this list was built: a public Three.js footprint first, headcount last

Every company was checked on its own website, and on Clutch where a profile exists, on September 20, 2026. To qualify, a vendor had to name Three.js, React Three Fiber or WebGL in its stack, or show a shipped browser-rendered project. Studios whose sites expose nothing but a tagline were left out.

The order follows fit to three buyer jobs: brand experiences, product-integrated 3D built with React Three Fiber, and platforms for large catalogs. 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 figure is not published, the table says so; nothing is estimated.

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

The ten studios, in order of fit

1. Active Theory: a small Los Angeles team with a published floor

Active Theory was founded in 2012 in Los Angeles and describes itself as blending "story, art & technology as an in-house team of passionate makers" with its own web toolset. It is the one creative studio here with a public price signal: Clutch lists a $25,000 minimum project and a $150–199 hourly band.

Its work page requires JavaScript to render, so verify named projects in a browser. Pick Active Theory for a campaign or launch experience where a senior team of two to nine people and a mature toolset matter more than headcount. When not to pick them: the team is small, no timeline is published, and a configurator with ERP wiring and a long maintenance tail is a different job from the brand work the studio is known for.

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

makemepulse works from Paris and London and describes its mission as bringing "standout immersive experiences to everyone, everywhere": immersive web, mobile games and e-commerce. It sponsors Three.js Conf Paris, as direct a stack statement as a studio can make.

Published case studies include an AI shopping experience for Brunello Cucinelli, the Rösti Fall loyalty game for McDonald's France, and Benno's Light for the Claims Conference. Pick makemepulse when the brief is a brand moment or a game-like retail activation. When not to pick them: no budget, timeline or headcount is published, and the portfolio is campaign-led, so an enterprise configurator with pricing rules is not where its public work sits.

3. LUSION: one Bristol team for design, motion, 3D and code

LUSION Creative Studio, based in Bristol, UK, says it combines "design, motion, 3D, and development" into visually striking digital experiences. Its project pages include Dream Machine for Porsche, Oryzo AI and Atlas Motion, pieces where the 3D scene carries the narrative rather than decorating it.

The argument for LUSION is that design and engineering come from one room, removing the hand-off where WebGL projects lose fidelity. Pick it for a single high-craft experience where visual quality is the deliverable. When not to pick them: founding year, headcount and pricing are not published, and there is no Clutch profile to cross-check, so the first call has to cover team size, availability and what happens when a project outgrows its scope.

4. A Culver City studio with published brackets and R3F in its stack

The Culver City, California studio Todor3D was founded in 2020 and reports 40+ engineers across three continents and 300+ delivered projects, with 25 reviews and a 5.0 rating on Clutch. Its practice areas are 3D & Immersive, Custom Software Engineering and AI Solutions; its stack is WebGL, Three.js, React Three Fiber and WebAR/WebXR. Unusually for this list, it publishes brackets: $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 in the $10,000–50,000 bracket with a four-month timeline, and a jewelry configurator in the same bracket. Pick the studio for a Three.js or R3F configurator with custom software behind it, a US contracting entity, and a bracket to plan against. When not to pick them: founded in 2020, the track record is shorter than the 2005 and 2006 vendors here, and the site publishes no engineering write-ups, so ask for a technical walkthrough of a shipped R3F project first.

5. darkroom.engineering: React Three Fiber inside a Next.js product

darkroom.engineering, formerly Studio Freight, is a distributed studio across Spain, Italy, France, Argentina and the USA. It describes its job as turning "ambitious digital ideas into reliable products", from design and full-stack development to motion, WebGL and headless commerce.

The published stack is the most complete of any studio here: WebGL, Three.js, React Three Fiber, Lenis, Next.js and GSAP, plus Sanity, Contentful and HubSpot. Listed work includes Ibicash, the Bad Omens site, and Framer as a client. Pick darkroom when the 3D element sits inside a real product, next to a CMS and a store, and one team should own all of it. When not to pick them: no pricing, headcount or timeline is published, and a team spread over five countries needs an explicit agreement on overlap hours before a US buyer signs.

6. basement.studio: an R3F studio that publishes how it builds

basement.studio calls itself "a digital studio crafting brands, websites, 3D experiences, and products". Listed work includes Vercel Ship, Daylight, KidSuper and Shop MrBeast, with Avionix and Ranboo on its about page.

What earns it a place on a Three.js list is its engineering blog. The "bsmnt chronicles" post documents React Three Fiber with Drei and PostProcessing, Three.js, GSAP, Next.js and Vercel, a camera system built on Drei's camera controls, and a WebGL ticker that keeps shaders in sync. That is detail a technical lead can evaluate. Pick basement for a consumer or commerce brand that wants a documented R3F build. When not to pick them: headquarters, headcount and pricing are not published, so contracting entity, time zone and budget floor must be settled in the first conversation.

7. Noomo: 3D storytelling sites from Los Angeles with six-figure brackets

Noomo is a Los Angeles studio with a San Francisco presence that builds "3D storytelling websites and immersive digital experiences where craft and narrative become one". Services cover 3D websites, WebGL development, brand video and AI-driven experiences; clients listed include Vogue Business, Salesforce and Intel's ai.io.

Noomo is one of two vendors here that publish brackets: $50K–100K, $100K–300K and $300K+ on its own site. Pick Noomo for a narrative-led site, a US contract and a budget that starts at $50,000. When not to pick them: the floor rules out the typical Clutch band, no timeline is published, and the portfolio is storytelling rather than configurator work, so option logic and pricing rules belong with a product studio.

8. Utsubo: a technology-first studio already working in WebGPU

Utsubo works from Osaka and Kyoto and describes itself as "a technology-first creative studio crafting ambitious digital experiences with no technical limits": web, games and interactive installations. Its named stack is WebGPU, WebGL and Three.js, a rare public WebGPU statement on this list.

Its own blog lists BMW, Louis Vuitton, Warner Music, Kia, League of Legends and JR as clients. Pick Utsubo when the brief pushes the browser to its limit, or when an installation and a web experience share one pipeline. When not to pick them: the client list is self-published without case-study detail, pricing is not published, and the Japan time zone leaves a US buyer a narrow window for daily contact.

9. MetaDesign Solutions: a 400-engineer offshore bench with a documented pipeline

MetaDesign Solutions is a Gurugram, India software company founded in 2006, with Brisbane and Detroit offices and 400+ engineers on its site. Its Three.js service line covers configurators, architectural visualization, WebXR and 3D data visualization, with more than 20 shipped Three.js projects claimed.

The technology page is specific: Three.js, React Three Fiber as "our default for React projects", Drei, Zustand, WebGPU, GLSL, glTF with DRACO and KTX2, WebXR and Rapier. The price argument is regional: Clutch's most common band is $25–$49 an hour in India against $50–$99 in the US (Clutch pricing guide, September 2026). Pick MetaDesign for a larger team at an offshore rate. When not to pick them: the Three.js case studies are anonymised, the Samsung and Coca-Cola logos are not tied to 3D work, and no pricing is published, so ask for a reference call on a named Three.js project.

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 platform rather than a studio: a 3D configurator, AR and AI guided selling integrated with CPQ, ERP and commerce systems. Its site cites its Three.js contribution and claims 200+ global brands.

Published case studies include Andersen Windows & Doors, Sloan and Ulrich Lifestyle Structures. Threekit reports a 95% increase in website leads at Andersen when customers engage its AI sales agent, a vendor-reported, single-customer figure with no baseline (Threekit homepage, 2026). Pick Threekit when the product has hundreds of configurable SKUs and sales already runs on CPQ. When not to pick them: pricing is not published, and you are buying a platform with its constraints, not a bespoke experience.

How to choose for your own project: four questions that separate a vendor from a portfolio

Write down the job first: launch experience, product-integrated feature or catalog. Then ask every shortlisted vendor the same questions.

1. Which shipped project is closest to ours, and can we speak to that client? A logo wall is not an answer; ask for the live URL and a client-side contact.
2. What is the asset budget per scene, and how do you enforce it? The median web page already weighs 2,652 KB on desktop (HTTP Archive Web Almanac, 2024); one uncompressed model can exceed that alone. A serious vendor names a megabyte target and its compression, such as Draco, which cut a Khronos sample buggy's geometry from 7.6 MB to 0.82 MB (Cesium benchmark, 2018).
3. What does year two cost? Agencies surveyed by GoodFirms budget maintenance at 15–25% of build cost per year (GoodFirms, 2026). A vendor who cannot name a retainer has not thought about it.
4. How will the 3D piece talk to our stack? For a configurator, that means the pricing source, the CMS and the order path; a studio that has only built stand-alone pages will hesitate.

FAQ: the questions buyers ask before hiring a Three.js studio

What does a Three.js development company actually do?

It builds interactive 3D that runs in a browser without plugins: configurators, 3D product pages, launch experiences, data visualizations and browser games. Three.js is an open-source JavaScript library on top of WebGL; React Three Fiber (R3F) wraps it for React. The work covers asset preparation, scene and shader programming, performance tuning for phones, and integration with the system that feeds the scene its data.

How much does Three.js development cost?

Clutch reports $10,000–$49,000 as typical, with an average total of $132,480 skewed by enterprise work (Clutch pricing guide, September 2026). On this list, Active Theory's minimum is $25,000, Noomo's brackets start at $50,000, and the Culver City studio's entry bracket is $10,000–50,000. Senior developer rates run $110–$200+ an hour in the US and $30–$70 in India (GoodFirms survey of 267 app companies, 2026).

How long does a Three.js project take?

Between one month and a year. Only one vendor here publishes timelines: 4–10 weeks for a small build, 3–6 months for a mid-size one and 4–12 months for a large program. Asset preparation is the hidden variable, because CAD or photography has to become optimized glTF before scene work starts, so ask for a schedule split into asset pipeline, build and device testing.

Three.js or React Three Fiber: which one should I ask for?

Ask for React Three Fiber if your product is already built in React; ask for plain Three.js if it is not. R3F keeps the 3D scene inside the same component tree as your forms and checkout, which is why darkroom.engineering and basement.studio build with it and MetaDesign Solutions calls it its default for React projects. A stand-alone campaign page is simpler in plain Three.js.

Will a 3D scene slow down my website?

Only if the assets are unmanaged. The model-viewer maintainers advise that a few megabytes is rarely exceeded for high-quality mobile rendering with proper compression, and that files above about 20 MB are a problem (google/model-viewer maintainer guidance). Speed has a price: across 10 million Renault visits, each one-second improvement in Largest Contentful Paint was associated with a 13% higher conversion rate (web.dev case study, 2021). Lazy-load the scene and keep the first paint free of 3D.
