Stride

Stride, formerly Xenko, is a free and open-source cross-platform C# game engine for building 2D and 3D games and applications. It is highly modular and designed for realistic rendering and VR, giving game makers flexibility in how they build. Game Studio, the bundled editor, lets you create and manage game content visually.

You can also skip the editor entirely: Stride ships CLI templates that scaffold a project from the command line, including genre starters for FPS, 2D platformer, top-down RPG, third-person platformer, and VR. Games are written in C# on .NET, with Direct3D and Vulkan graphics backends.

Stride is MIT licensed and supported by the .NET Foundation. The engine builds from source on Windows, with optional iOS, Android, and ARM64 components, and a community toolkit of C# helpers extends it further.
