Blend4Web: Award-Winning 3D Web Solution

Blend4Web is a tool for creating interactive, web-based 3D content. The framework can be used for showcasing products, e-learning, game development, advertising and web design.

Why Blend4Web?

  • It works right in the web browser without installing any plug-ins (thanks to WebGL);
  • Not only does it render 3D graphics but it also integrates realistic physics and spatial audio;
  • It is extremely simple to use because it is based on Blender in which 3D scenes can be made and then directly exported, even as a standalone web page;
  • It is available as a fully functional open source version or as under a paid commercial license.
  • It does not depend on any non-free components or cloud services.

This repo mirrors the community edition SDK distribution which can also be downloaded from the official site.

What's Next. Basics

To reveal the engine settings, select Blend4Web from the upper panel menu.

Fast Preview

Preview scenes using Fast Preview button, located both at the bottom of the 3D View window and under the Render tab. In this case the scene will be exported inside some temporary storage and opened with the Scene Viewer.


Select either Blend4Web (.html) or Blend4Web (.json) option from the File > Export menu.

Exported HTML files are self-contained and can be opened with a generic browser right away. On the other hand, exported JSON (together with BIN) files should be opened with the stock Web Player or loaded into your own 3D web app. See this tutorial for more info.

SDK Index Page

Under the Render tab click SDK Index. The SDK index page will be opened in the default browser. Look through the demos, read the docs, run the Project Manager.
