Comparison · Threekit vs Obox
The photorealistic Threekit alternative built for jewelry.
- Real-time ray-traced gemstones - actual physics, not PBR approximation.
- Embed on Shopify, WooCommerce, BigCommerce, Magento, Webflow via a snippet - no enterprise IT project.
- Mobile-first WebAssembly stack - smaller payload than JavaScript-based configurators.
- Engineering partnership - your models, our build, no DIY dashboard to operate.

Choosing between Obox and Threekit
We respect what Threekit built. They're not the wrong choice - they're the wrong shape for some of our customers.
Choose Obox if
- You're a jewelry brand and gemstone fidelity is core to the purchase decision.
- You want a fast time-to-launch on Shopify Plus, WooCommerce, BigCommerce, or Magento - embed via a snippet, no enterprise-IT integration project.
- Mobile performance matters - dormant on the product page, lightweight payload, WASM-accelerated render.
- You want sales-led pricing scoped to your project - not enterprise contracts sized for Fortune 500 budgets.
Choose Threekit if
- You need one platform across automotive, furniture, fashion, and jewelry - multi-vertical consistency matters more than per-category depth.
- You have enterprise IT infrastructure ready to integrate via their REST API and 3D Studio workflow.
- Your gemstones are accent details, not the primary visual subject of the product.
01 · Jewelry-native
Built for jewelry, not retrofitted from another vertical.
Threekit serves an admirable breadth of categories - automobiles, furniture, fashion, eyewear, and jewelry - all from a single platform. That breadth is its strength for multi-product enterprises. For a jewelry brand, it also means the shader library, the model conventions, and the configuration logic were designed against a generic shape.
Obox was built first for jewelry. Our material presets ship with the metals jewelry brands actually sell. Our gemstone library is tuned for the optical properties of jewelry stones. Our model conventions handle the geometry of rings, pendants, and bridal pieces - including the constraints of stone-setting (prong, bezel, channel, pavé) that don't apply to furniture or footwear.
Generic 3D platforms cover many verticals well enough. A jewelry-specialised platform delivers depth specifically for rings, pendants, and bridal collections - the same way developer-focused tools tend to outperform generalist ones for engineering teams.
02 · Real-time photorealism
Ray-traced gemstones - physics, not approximation.
The optical behaviour of gemstones - is what gives jewelry its life. Approximating these effects with flat or PBR shaders produces a stone that reads as a coloured ball. Computing the physics in real time produces a stone that reads as a stone.
Most web-based 3D configurators in this space - including Three.js-based stacks - use PBR materials. PBR is fast and broadly correct for matte and metallic surfaces, but it can't represent the chromatic dispersion or multi-bounce internal reflections that give gemstones their characteristic sparkle.
Obox uses real-time ray-tracing specifically for the gemstone passes - refraction is computed with separate IOR values for the red, green, and blue channels, which is what produces visible chromatic dispersion. The output is a diamond that breaks light the way a real diamond does. For jewelry, where the gemstone is often the most expensive component of the piece, that fidelity is the product.
03 · Mobile-first performance
Lighter payload, faster on the device shoppers actually use.
Premium jewelry browsing happens on mobile. Mobile makes up the majority of e-commerce traffic across fashion and accessories - the device a shopper uses to consider a ring is more often a phone than a desktop. A configurator that delivers a desktop-class experience but ships a desktop-class payload is the wrong trade-off for jewelry.
Obox compiles its renderer to WebAssembly from Rust. WebAssembly modules typically parse and execute faster than equivalent JavaScript on mobile devices, with more predictable memory behaviour than JavaScript's garbage collector can deliver. JavaScript-only 3D stacks pay a parse-and-execute tax on every interaction.
On the product page, the Obox widget is dormant until a shopper opens it: zero impact on Largest Contentful Paint, Cumulative Layout Shift, or Interaction to Next Paint. When activated, the configurator targets 60 fps on mid-tier mobile devices from the last several years - the device floor jewelry retail actually has to support.
