About

About Flax Engine

Flax Engine is a 3D game-development environment with an editor, project tools and C# and C++ workflows. The official launcher downloads and manages the engine. Samples and documentation give developers a practical starting point for evaluating a small project.

Does InstallFlax.exe contain the complete engine?

It installs Flax Launcher, which then installs and manages engine builds. This page links the official rolling launcher endpoint rather than claiming a fixed Flax Editor version.

How do I install it?

Run InstallFlax.exe and follow the launcher setup. Review the EULA, install an engine build and create or open a project. The engine is a separate download; the installer size on this page is the launcher package.

What does it cost?

Flax is available to download and evaluate under its EULA. Commercial releases can incur royalties; the public licensing page explains its current 4% model and revenue threshold. Publicly viewable source does not make Flax an unrestricted open-source engine. Official terms: https://flaxengine.com/licensing/
