What is Blend4Web?

Blend4Web is a framework for building interactive 3D content that runs directly in web browsers. It lets you create 3D scenes and applications using Blender as your design tool, then export them to web-ready formats without needing to rebuild your models in separate software. The platform includes a physics engine for simulating realistic object behaviour, making it suitable for product visualisers, educational simulations, games, and architectural previews. You can develop anything from simple interactive models to complex applications, and the freemium model means you can start experimenting without upfront costs.

Pros & cons

Advantages

Familiar workflow for Blender users; no need to learn a different design interface
Built-in physics engine saves time compared to integrating external libraries
Runs in browsers with no installation required; easy to share and deploy
Free tier lets you build and publish projects without paying

Limitations

Smaller ecosystem and community compared to alternatives like Three.js or Babylon.js
Performance on older devices or with very large 3D models can be limited
Commercial licensing required for some use cases; check terms if building for clients
