An open-source, multi-platform 3D engine for building AAA games, cinema-quality worlds, and high-fidelity simulations.
O3DE (Open 3D Engine) is an open-source, real-time 3D engine that enables the creation of AAA video games, cinema-quality 3D worlds, and high-fidelity simulations. It is licensed under Apache 2.0, meaning developers can use it without any fees or commercial obligations. The engine is designed to be multi-platform and supports a project-centric workflow for flexible development.
Game developers, simulation engineers, and 3D content creators working on professional-grade projects requiring a free, open-source alternative to commercial engines.
Developers choose O3DE for its fully open-source model under a permissive Apache 2.0 license, eliminating licensing costs and restrictions. It offers a modular, extensible architecture suitable for AAA-quality projects across multiple platforms, backed by a community-driven development process.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Licensed under Apache 2.0, allowing free use, modification, and distribution without any fees or commercial obligations, as highlighted in the GitHub description.
Built to meet high-performance standards for top-tier game development, enabling cinema-quality 3D worlds and simulations, per the key features.
Enables development and deployment across various operating systems and hardware, making it versatile for different target platforms.
Supports integration of third-party SDKs like Wwise audio engine, as noted in the optional requirements, allowing customization for professional workflows.
Requires multiple steps with Git LFS, CMake, Visual Studio workloads, and manual configuration, as detailed in the installation guide, which can be time-consuming and error-prone.
As a newer open-source project, it lacks the extensive asset libraries, tutorials, and plugin ecosystems of established engines like Unity or Unreal Engine.
Documentation is spread across external sites (o3de.org) and may have gaps or be less comprehensive compared to commercial engines, relying on community contributions.
O3DE is an open-source alternative to the following products:
Unity is a cross-platform game engine and development environment used to create 2D, 3D, VR, and AR games and interactive experiences.
Unreal Engine is a powerful real-time 3D creation tool developed by Epic Games, used for game development, film production, architecture visualization, and other interactive experiences.
