Bevy vs Stride

Bevy is a free, open-source game engine built in Rust for 2D and 3D games, visualizations, interfaces, and other graphical applications. It uses a custom Entity Component System, with components represented as Rust structs and systems as Rust functions. The engine includes 2D and 3D rendering, a composable render graph, skeletal and morph-target animation, scene loading, hot reloading, UI, and audio playback. Its 2D renderer supports sprites, texture atlases, cameras, materials, custom shaders, and render pipelines. The 3D renderer includes lights, shadows, meshes, materials, cameras, and glTF loading. The ECS-driven UI framework uses flex-box layout and can be composed in code or scenes. Scene changes can update running applications; hot reloading currently covers scenes, textures, and meshes. Bevy targets Windows, macOS, Linux, web, iOS, and Android, and is available through crates.io with cargo add bevy. Users choose MIT or Apache 2.0 licensing, with no license fees or sales cuts. It remains in development, with possible missing features, sparse documentation, and breaking API changes about every three months.

Stride is a free, open-source C# engine for building 2D and 3D games and interactive content on desktop and VR. Game Studio manages assets, scenes, sprites, interfaces and curves. The engine provides physics, navigation meshes, visual scripting, physically based materials, light probes, particles, post effects and customizable shaders, with DirectX 12 and Vulkan graphics APIs. C# 14, .NET 10, asynchronous scripting and hot reload are supported. Native Oculus and HTC Vive support includes VR previewing from the scene editor. Stride exports to Windows, Linux, Android and iOS, and is free to use, modify and distribute under the MIT license. Listed development requirements include Windows 10 or 11, an x64 CPU, a Direct3D 10-or-newer GPU, 4 GB RAM and 5 GB disk space. The project describes itself as community-driven, without full-time developers dedicated solely to its advancement.
