What is O3DE (Open 3D Engine)?

O3DE (Open 3D Engine) is a free, open-source, cross-platform, real-time 3D engine used to build games, cinema-quality worlds, and high-fidelity simulations. It is distributed under the Apache 2.0 license with no fees or commercial obligations. The engine uses a modular Gems architecture, so developers add or remove functionality like physics, rendering, or networking as precompiled modules, and it includes a physically based renderer, a prefab system with human-readable, source-control-friendly assets, and Python 3 scripting for extending the editor.

O3DE is developed under the Open 3D Foundation, part of the Linux Foundation, with an active open-source contributor community. Projects are built using CMake and each developer's native IDE and toolchain, making it suited to teams that want full control over engine source and build pipelines without licensing costs.
