Top 10 companies building browser-based 3D viewers

The short answer: a platform when the viewer is the product, a pipeline when the problem is the CAD, a studio when the viewer must live inside your own stack

For a manufacturer that needs a viewer wired to configuration and quoting, start with Threekit or Zea; for a company whose real problem is thousands of CAD files that never reach the web, start with VNTANA; for a brand that wants a hosted viewer on product pages next week, look at Emersya, Zakeke or Vectary; when the viewer has to sit inside your own React front end and talk to your own PIM or ERP, hire a custom studio such as the Culver City team at #5. The upside is measurable but vendor-reported: in Shopify's Rebecca Minkoff case study (Shopify blog, 2020–2021 cohort, single-merchant data), shoppers who viewed a 3D model were 44% more likely to add it to cart and 27% more likely to order. For a custom build, budget from the typical Clutch project band of $10,000–$49,000 (Clutch pricing guide, updated September 2026).

How this list was built: fit to the viewer job first, headcount and funding ignored

The job we ranked against is narrow on purpose: a 3D model of a real product, machine or site opens in a browser tab, on a phone as well as a desktop, without a plug-in or an app, shows the right variant, and loads fast enough that the visitor does not leave. Vendors that cover more of that job, from converting the source geometry to rendering it in WebGL or WebGPU to connecting the viewer to the systems that hold the truth about the product, sit higher.

Every company was checked on its own website on September 20, 2026, and where noted on its Clutch listing. Where a vendor does not publish a price, a timeline or a city, the table says "not published" rather than guessing. Customer results quoted by vendors are labeled as the vendor's own data, because none come with a method or a baseline.

The order is by fit, not by size or funding: an enterprise configuration platform sits at #1 and a geospatial engine at #8 even though it renders more 3D data than anyone else here, because it is the right choice for a city, not for a chair. Deliberately ignored: Clutch review counts, which reward age over quality; award lists; and the "AI" label, since nearly every vendor added one this year. Region was not a ranking factor, but four of the ten are US-based and one is Canadian, since a US buyer usually wants a North American contract.

The comparison table: what each vendor publishes about focus, budget, timeline and region

The budget and timeline columns contain only figures the vendor publishes on its site, pricing page or Clutch listing. Only one of the ten publishes a budget bracket and a timeline; for the rest, the first conversation is a scoping call, and the quote depends on how many models you have and how clean the source files are.

The ten companies: what each does, a representative project, and when to pick it

1. Threekit: a viewer that is also a configurator and a quoting tool

Threekit is a Chicago company founded in 2005. Its platform sells complex configurable products: a WebGL viewer and 3D configurator, AR output, and what the site now calls an AI sales agent that turns a buyer's requirements into a valid configuration and a quote through the customer's existing CPQ, ERP and commerce systems.

Representative projects on its site include Andersen Windows & Doors, Sloan and Ulrich Lifestyle Structures. Threekit's own data claims a 95% increase in website leads for Andersen from the AI sales agent and 4× faster quoting at Sloan (Threekit homepage, 2026, vendor-reported, no baseline); it also reports 150+ manufacturers live.

Pick Threekit when the viewer is the front end of a sales process: rules, pricing and a quote have to come out of the same model the buyer rotates. Do not pick it for a catalog of simple products with no option logic; pricing is not published, and the CPQ integration is where the budget goes.

2. VNTANA: the pipeline that gets CAD into a web viewer at scale

VNTANA is based in Van Nuys, in the Los Angeles area, and describes itself as enterprise digital asset management software that automatically converts, optimizes and publishes 3D and CAD assets to every channel. It accepts 40+ CAD formats, including SolidWorks, Revit, Creo, CATIA, STEP and JT, and outputs GLB, USDZ, FBX, OBJ and STL. An enterprise web viewer comes with it, along with an API, webhooks and connectors to PLM, ERP, PIM and ecommerce systems such as PTC Windchill and Centric PLM.

Its case-study page lists Kohler, Bobcat and Michaels. Pricing is custom enterprise licensing scaled to storage and live 3D models, with a free trial for standard formats (site, checked September 2026); no figures are published.

Pick VNTANA when the blocker is not the viewer but the thousands of engineering files behind it: a manufacturer with a Windchill vault and a website that still shows line drawings. Do not pick it when you have fifty products and a designer who can export a GLB by hand, or when you need a bespoke front end.

3. Emersya: hosted 3D viewers and customization for consumer brands

Emersya has been around since 2012, per its copyright line, and positions itself as an all-in-one 3D and AR platform for online product customization, immersive visualization and rendering automation for brands and retailers. The output is a WebGL viewer embedded on a product page, an AR view on mobile, and automated renders from the same 3D master, so the product imagery and the viewer never disagree.

The site shows a Samsonite C-Lite viewer, a Salomon colorway design tool and a Beyerdynamic headphones viewer; its case-study page also names Vacheron Constantin, Whirlpool and Factor Bikes. A pricing page exists, but figures are not published.

Pick Emersya when you are a consumer brand with a finished catalog, good modeled assets, and a marketing team that wants viewers, configurators and render automation from one vendor without hiring engineers. Do not pick it when the viewer has to encode engineering rules or feed a quote, or when your team needs to own the rendering code; you are renting the viewer.

4. Zea Inc: CAD-to-browser digital twins for industrial products

Zea is a Montreal company whose tagline is that it transforms CAD and business data into interactive digital twins, from production to sales, documentation and after-sales support. The products sit on Zea Engine, a WebGL-based 3D engine with CAD integration, and include configurators, interactive parts catalogs, technical illustrations and a SimStream visualizer for CAE results.

Success stories on the site cover Trebro, Motrec and Taiga Motors: industrial vehicle and equipment makers whose assemblies run to thousands of parts. No pricing, timeline or team size is published.

Pick Zea when the same 3D model has to serve sales, service manuals and a parts lookup, and when the source is a large CAD assembly rather than a designed marketing asset: a dealer clicking a part on an exploded view to order it is exactly the case. Do not pick it for a consumer product page or a brand experience; the engine is built for engineering data.

5. A custom viewer build shop in Culver City: Three.js and React Three Fiber inside your stack

Todor3D is an immersive web development studio founded in 2020, with 40-plus engineers across three continents, 300-plus delivered projects and 25 reviews at a 5.0 rating on Clutch. Its stack is WebGL, Three.js, React Three Fiber and WebAR/WebXR, and its practice areas are 3D & Immersive, Custom Software Engineering and AI Solutions. The homepage lists a closet configurator in the $10,000–50,000 bracket built over four months and a jewelry configurator in the same bracket.

Unlike the platforms above, what you get is code you own: a viewer component built into your own React front end, with the asset pipeline, the variant logic and the integration to your PIM, ERP or cart written for your case. The published brackets run from $10,000–50,000 to $100,000–250,000+, with timelines from 4–10 weeks to 4–12 months, which is unusual on a list where most vendors publish nothing.

Pick the studio when the viewer must match your design system, when the data behind it lives in systems no platform connector covers, or when you want no per-model license fee at scale. Do not pick it when a hosted platform already does what you need at a monthly price, or when you want a fifteen-year track record; its history is shorter than Threekit's or Emersya's, and you will be maintaining the code after handover.

6. Soft8Soft (Verge3D): a toolkit for teams that already model in Blender or 3ds Max

Soft8Soft makes Verge3D, a toolkit for web interactives, product configurators, e-learning and browser games built from Blender, 3ds Max or Maya scenes, with a no-code logic system called Puzzles. The copyright line dates the company to 2017. It is Three.js-based, and its manual is candid: UASTC-compressed textures can come out up to 3× larger than the source image over the network, so Verge3D keeps the original when that happens (Soft8Soft Verge3D manual, texture compression chapter).

Projects linked from the site include the NASA/JPL Mars rover simulator on eyes.nasa.gov, a Volvo Cars 3D showroom and a GE Digital Energy testimonial. Licenses are sold per product; prices were not captured, and no headquarters is published.

Pick Verge3D when you have an in-house 3D artist who lives in Blender or Max and you want that person to ship a viewer without a JavaScript developer. Do not pick it when nobody on your team models, when you need deep commerce integration, or when you want a vendor accountable for the result; it is a tool, not a service.

7. Vectary: a browser design tool with an embeddable viewer and AR output

Vectary is a fully browser-based 3D design tool with photorealistic real-time rendering, augmented reality, interactions and animations, built to create and share 3D content for the web. It imports CAD, supports VR headsets, and outputs a web viewer that can be embedded on a page. Its homepage shows a logo wall with Panasonic, NASA and Sharp, but no case-study pages, and it publishes neither pricing, headquarters nor team size.

Pick Vectary when the person producing the viewer is a designer rather than an engineer, the products are visually simple, and the goal is a quick embedded viewer or AR preview for a landing page or a pitch. It is also a reasonable way to prototype before committing to a custom build. Do not pick it when you need volume, governance or a viewer that pulls variant data from a back end, and ask for references before signing.

8. Cesium GS: the viewer for cities, sites and anything with coordinates

Cesium is a Philadelphia company that calls itself the open platform for software applications designed to unleash the power of 3D data. Its stack is CesiumJS, an open-source WebGL viewer for geospatial data; 3D Tiles, an OGC standard for streaming massive models; and Cesium ion for hosting and tiling. A free community account exists on Cesium ion; enterprise pricing is not published.

Its engineering blog has the most concrete public numbers on this list. Draco compression took a 1.1-million-building New York City tileset from 738 MB gzipped to 179 MB and load time from 18.9 s to 10.5 s (Cesium blog, April 2018, engine vendor benchmark, geometry only).

Pick Cesium when the thing being viewed has a location: a construction site, a wind farm, a city district, a drone survey. Do not pick it for a product on a white background; a single chair does not need a globe, and the effort goes to tiling and streaming, not to materials and lighting.

9. Zakeke: a hosted viewer and customizer for D2C storefronts

Zakeke is a Milan-based SaaS platform that describes itself as an AI platform for D2C brands and manufacturers, connecting 3D, customization and virtual try-on with automated workflows. It plugs into ecommerce storefronts with a WebGL viewer, an AR view and an API, and sells through self-serve tiered plans plus an enterprise tier with a free trial (site, checked September 2026); the figures were not captured.

Success stories on its resource hub include La Fabrique à Sachets, Design Italian Shoes and Kaze Club: small and mid-sized brands whose products are personalized rather than engineered. Its homepage claims 25,000+ brands, the vendor's own figure.

Pick Zakeke when you run a Shopify, WooCommerce or similar store, your products come in colors, materials and printed options, and you want a viewer live in weeks. Do not pick it for industrial products, for a catalog that needs CAD conversion at scale, or for a bespoke front end; it is a hosted layer on top of your store, and it looks like one.

10. VisCircle GmbH: a German agency for custom configurators and viewers

VisCircle is a German agency founded in 2013 that calls itself your digital agency for 3D configurators and interactive web experiences. Its projects page lists a Volkswagen AG Virtual Studio, a lighting configurator for Allied Maker in the United States and work for Ege Carpets of Denmark. No stack, pricing, timeline, team size or city is published on the pages we fetched.

Pick VisCircle when you are a European manufacturer, or a US brand with European operations, and want a custom configurator from an agency with a decade of the same specialization. Do not pick it if you need a documented technology stack before signing, a US contract and time zone, or a price bracket before the first call; none of that is public, and it is here as a specialist, not because it is easy to evaluate.

How to choose for your own project: five questions that separate a viewer demo from a viewer that ships

Most viewer demos look the same on a vendor's laptop; the differences show up on a mid-range Android phone and in the month after launch. These five questions surface them before the contract.

1. What does the final model weigh in the browser, and how did you get it there? The median web page in the HTTP Archive Web Almanac 2024 weighs 2,652 KB on desktop and 2,311 KB on mobile, so a single uncompressed model can outweigh the entire page around it. Ask for a target in megabytes and the pipeline that hits it: Draco or meshopt for geometry, KTX2 for textures, level-of-detail switching. A vendor who cannot name a number has not done it at your scale.

2. Where do the variants come from? If the viewer shows options, ask which system is the source of truth and how the viewer reads it. A configurator that stores its own option list will drift from your ERP within a quarter. Gartner's 2025 survey of 632 B2B buyers found that 69% reported inconsistencies between website information and what sellers told them (Gartner, June 2025); a viewer that disagrees with the quote adds to that number.

3. What happens on a phone that cannot run it? WebGL fails on some devices and some corporate browsers, so ask what the fallback is: a static render, a video, a message. Ask for the load-time target too: Renault measured a 13% conversion lift for every second of Largest Contentful Paint improvement across 10 million visits (web.dev case study, 2021), and a 3D viewer is the heaviest thing on most product pages.

4. Who owns the code and the assets after launch? With a platform, you rent the viewer and keep the assets; with a studio, you should own both, so put the repository, the build pipeline and the source files in the contract. GoodFirms' 2026 app-cost survey of agencies puts maintenance at 15–25% of build cost annually; ask who does that work and at what rate.

5. Show me one project like mine and let me talk to the client. Vendor-reported results on this list have no baselines. A 20-minute reference call with a buyer in your industry tells you more than a case-study page; if the vendor cannot arrange one, weigh that against the size of the bet.

Frequently asked questions from buyers comparing 3D viewer vendors

What is a browser-based 3D viewer?

A browser-based 3D viewer is a component on a web page that renders a 3D model in real time with WebGL or WebGPU, so a visitor can rotate, zoom, change options and sometimes view it in AR without installing an app or a plug-in. The model is usually a glTF or GLB file, and the viewer either comes from a hosted platform or is built with a library such as Three.js.

How much does it cost to build a 3D product viewer?

A custom viewer typically lands in the $10,000–$49,000 band that Clutch reports as the most common software project size (Clutch pricing guide, updated September 2026); the one vendor on this list that publishes brackets lists $10,000–50,000 and 4–10 weeks for a small scope. Platform fees are mostly unpublished. The largest variable is asset preparation: converting and optimizing CAD often costs more than the viewer code.

Can a 3D viewer connect to our ERP or PIM?

Yes, and that is the main reason to choose one vendor over another. Threekit connects configurations to CPQ, ERP and commerce systems; VNTANA offers an API, webhooks and PLM, ERP and PIM connectors; Zea reads CAD and business data together; a custom studio writes the integration for your specific systems. Ask which system remains the source of truth for options and prices.

How large can a 3D model be for the web?

A few megabytes is the practical ceiling for a product viewer on a phone. The google/model-viewer maintainers advise that it is rarely necessary to use more than a few MB for high-quality rendering on a mobile device with proper compression, and that files over about 20 MB should be treated as problematic (model-viewer GitHub discussion #2716).

Do 3D viewers actually increase sales?

The published evidence is positive but vendor-reported and single-brand. In Shopify's Rebecca Minkoff case study (Shopify blog, 2020–2021 cohort), shoppers who viewed a 3D model were 44% more likely to add to cart and 27% more likely to order; Gunner Kennels reported a 5% lower return rate after adding 3D models (Shopify blog). On the demand side, Baymard's product-page benchmark finds 25% of ecommerce sites lack images with sufficient resolution or zoom (Baymard Institute, 2025–2026), which is the gap a viewer fills. Run your own A/B test before extrapolating.

Should we build a viewer or use a platform?

Use a platform when your products are standard, your catalog is large and a monthly fee is acceptable; build when the viewer must match your front end, pull data from systems no connector covers, or avoid per-model fees at scale. McKinsey's 2026 B2B Pulse found 73% of decision-makers are comfortable placing orders over $50,000 online (McKinsey, ~4,000 respondents, May 2026), so either way the viewer is a sales channel; choose on integration and ownership, not on the demo.
