What is it?

Nau Engine is a free and open-source game engine aimed at being versatile and accessible. The project states that it carries no licensing limitations, royalties or fees, and may be used for any purpose, including commercial work.

The entire source code lives in a Git repository, so developers can study it for educational purposes, build it themselves, create forks, or write add-ons. Development is open to outside contributors.

The engine is built for Windows with Visual Studio 2022 (MSVC v143 and the Windows 10 SDK), CMake presets, and Python 3.10 or newer. Dependencies are managed through vcpkg, and build output is installed into an output folder.
