The Best Spline Alternatives in 2026 for 3D Web and UI
Spline made 3D approachable for designers: a browser editor, a scene you can embed, and no render farm. People look for alternatives when they need real 3D modelling, when the scene has to be driven by app data, or when they want code instead of an embed.
We make ExodeUI, which is not a 3D tool. It appears here only for the interactive UI layer around a 3D scene. For the 3D work itself, the other tools on this page are the better choice.
Use Blender if you need real modelling, materials and physics and do not mind the learning curve. Use Womp or Vectary if you want browser-based 3D that is easier than Blender. Use Three.js or React Three Fiber if developers will build the scene in code and it has to react to app state. Spline is still the fastest path from a designer to an embeddable 3D scene, so switch when you hit a wall, not before.
Quick picks by job
| If you need | Use |
|---|---|
| Serious 3D modelling and rendering | Blender |
| Easy 3D in the browser | Womp |
| 3D product visuals for the web | Vectary |
| A 3D scene controlled by app code | Three.js and React Three Fiber |
| Interactive UI next to a 3D scene | ExodeUI |
How we compared them

- How much control you get over materials, lighting and animation
- What the output is: an embed, a video, a model file or code
The 5 best Spline alternatives
1. Blender
Best for: Real modelling, materials, simulation and rendering
- Platforms
- Windows, macOS, Linux
- Price
- Free and open source
- Output
- Rendered images and video, glTF and other model formats
Blender is the answer when Spline runs out of modelling power: proper topology, UVs, shaders, physics and a render engine. It exports glTF, which you can load in a web scene. The cost is time. Blender is a deep application, and a designer who only needs a floating shape will spend longer than they would in Spline.
Pros and cons
- Full modelling, sculpting and material tools
- Free with a very large learning library
- Exports glTF for web scenes
- Steep learning curve
- No one-click embed for a website
2. Womp
Best for: Designers who want soft, sculptural 3D without a modelling course
- Platforms
- Browser
- Price
- Free plan; paid plans available
- Output
- Rendered images and video, model export on paid plans
Womp is a browser 3D tool built around simple shapes, blending and materials. It is much closer to Spline in spirit than Blender is: open it, make something that looks good, export. It is strongest for product visuals and hero objects rather than animated, interactive scenes.
Pros and cons
- Very quick to get a good-looking result
- Runs in the browser with nothing to install
- Better materials than most design-tool 3D
- Less control over precise geometry than Blender
- Limited interactivity for web scenes
3. Vectary
Best for: 3D product visuals and configurators for the web
- Platforms
- Browser
- Price
- Free plan; paid plans available
- Output
- Embeddable 3D scenes and rendered images
Vectary sits between Spline and a product configurator tool. It has a browser editor, an embeddable viewer and support for real product models, which makes it a reasonable fit for e-commerce and product pages. The editor is less playful than Spline and more oriented to presenting a real object.
Pros and cons
- Embeddable viewer built in
- Handles imported product models
- Browser-based, so teams can share a link
- Less suited to stylised motion design
- Advanced features sit on paid plans
4. Three.js and React Three Fiber
Best for: 3D that has to react to real app state and data
- Platforms
- Any (JavaScript)
- Price
- Free and open source
- Output
- A 3D scene rendered in your own web app
If the scene needs to respond to scroll, a product variant, a user action or live data, code is usually simpler than an embed. Three.js is the underlying library and React Three Fiber wraps it for React. You lose the designer-friendly editor and gain full control, which is the right trade for a product team with front-end skills.
Pros and cons
- Full control over behaviour and performance
- Fits your existing build and design tokens
- No separate embedding workflow
- Requires a developer
- Easy to build something slow if you do not watch draw calls
5. ExodeUI
Best for: The 2D interactive UI that sits around a 3D scene
- Platforms
- Browser and desktop
- Price
- Free Community plan; Professional $29/month
- Output
- An open .exode file played by runtimes for web and mobile
ExodeUI does not model 3D. It handles the part that usually breaks a 3D landing page: the interface on top of the canvas, with states for loading, hover, selected variants and error. You design those states once and the same file runs in the app, so the 3D scene and the UI around it stop drifting apart.
Pros and cons
- State machines and springs for real UI states
- Same file on web and mobile
- MCP server for AI coding tools
- Not a 3D modelling or rendering tool
- No scene graph, lighting or materials
You have read the list. The one we make is one click away.
Free Community plan. One open .exode file that runs in React, Vue, Svelte, Angular, Solid, React Native, SwiftUI and Flutter.
Also worth a look
What Spline is still best at
Spline is the fastest way for a designer to make an attractive 3D object and put it on a page. The editor is friendly, the embed is a copy-paste, and the result loads without a developer. If that is your job, an alternative will probably slow you down. Look elsewhere when you need real modelling, real product data or tight control over performance.
Judge a 3D tool by what it does to page speed
A 3D hero can cost more performance than everything else on the page. Before choosing, check what the embed loads, whether it can be paused when off-screen, and how it behaves on a mid-range phone. Any tool that gives you a compressed model and a renderer you control will beat a heavy embed on a marketing page.
