Spline vs Three.js: no-code 3D or code 3D?
Spline is a visual, no-code 3D design tool; Three.js is a JavaScript library for building 3D from code. Which suits your project and skills?

Quick answer
Use Spline to design and ship interactive web 3D visually, with no code. Use Three.js when you need full control, performance and custom logic and have a developer to write it. Spline is fastest for designers; Three.js is most powerful for engineers.
Spline and Three.js both put 3D on the web, but from opposite ends. Spline is a visual, no-code editor — you design scenes, add interactions, and export or embed them without writing code. Three.js is a JavaScript library: total control, but you build everything in code.
So the real question is who's building it and how much control you need. Here's the honest breakdown.
| Dimension |  Spline |  Three.js |
|---|---|---|
| Approach | Visual, no-code editor | Code (JavaScript) |
| Speed to a scene | Fast — design and export | Slower — build in code |
| Control & flexibility | Good, within the editor | Total — anything is possible |
| Performance tuning | Limited | Full control |
| Who it's for | Designers | Developers |
| Custom logic | Built-in interactions | Unlimited (you code it) |
| Best for | Hero scenes & quick web 3D | Complex, performant 3D apps |
Choose Spline if…
- You're a designer who wants 3D without code
- You need a hero scene or product visual fast
- Built-in interactions cover your needs
- You value speed over deep optimisation
Choose Three.js if…
- You (or a dev) are comfortable in code
- You need full control and performance
- The 3D has custom logic or heavy scenes
- It's a real 3D app, not a single visual
The honest verdict
For a designer who wants an interactive 3D hero or product scene on a site, Spline wins on speed and ease. For a performance-critical, logic-heavy 3D experience built by a developer, Three.js is the right foundation.
Many great sites use Spline for a signature moment and hand-code the rest. Pick Spline to move fast as a designer; pick Three.js when control and performance are non-negotiable.
