Creating 3D animations for the web has never been easier. With the power of modern JavaScript libraries and WebGL, developers can now build interactive 3D scenes, immersive games, product visualizations, and much more—all running smoothly in the browser.

In this post, we’ll explore the top 5 JavaScript libraries for 3D animation that are leading the way in 2025. Whether you’re a seasoned developer or just getting started with 3D on the web, these libraries offer powerful tools to bring your vision to life.

1. Three.js

⭐ Best for: Full-featured 3D rendering and animation

Three.js is the most widely used JavaScript library for 3D on the web. It abstracts the complexities of WebGL and makes it easier to create and animate 3D objects, lights, cameras, and materials.

Key Features:

• Powerful rendering engine based on WebGL
• Support for lights, shadows, materials, and shaders
• Built-in animation system
• Works with external 3D models (GLTF, OBJ, etc.)
• VR and AR support

2. Babylon.js

⭐ Best for: Game development and immersive 3D experiences

Babylon.js is a powerful open-source 3D engine built for the web. It’s feature-rich and comes with its own playground for experimenting and prototyping 3D scenes.

Key Features:

• Full physics engine support
• WebXR ready (for AR/VR)
• Advanced material and lighting system
• Built-in GUI and audio engine
• Support for large scenes and complex interactions

3. GSAP (GreenSock Animation Platform)

⭐ Best for: Smooth, timeline-based animations

GSAP isn’t a 3D library on its own, but when combined with Three.js or Pixi.js, it becomes a powerful tool for animating 3D objects. Its performance and ease of use make it a favorite among developers and animators alike.

Key Features:

• Timeline and sequencing control
• Works well with canvas, SVG, WebGL, and CSS

Zdog is a pseudo-3D engine for creating delightful vector-style animations. It’s simple, fun, and perfect for adding character to your site or app without heavy WebGL overhead.

Key Features:

• Flat design with 3D-like perspective
• Easy to animate using built-in rotation and scale
• Great for logos, mascots, and playful visuals

5. Spline

⭐ Best for: Designers and no-code/low-code workflows

Spline is a web-based 3D design tool that lets you visually build 3D scenes and export them to your site using JavaScript. It’s ideal for designers and developers looking for a simple way to integrate 3D visuals.

Key Features:

• Visual editor for 3D design
• Built-in animations and interactions
• Easy JavaScript embedding
• Real-time collaboration

Final Thoughts

Adding 3D animations to your web applications is a great way to captivate users, enhance engagement, and showcase content in a memorable way. Whether you’re creating a game, an animated product page, or a unique portfolio, the right library can make all the difference.
