What Bevy is

Bevy is a free, open-source game engine written in Rust for building 2D and 3D games, visualizations, user interfaces, and other graphical applications. Its engine and game logic use a custom Entity Component System: components are Rust structs and systems are Rust functions. The 2D renderer includes sprite sheets, cameras, textures, materials, custom shaders, and render pipelines; the 3D renderer supports lights, shadows, meshes, materials, and glTF loading. Animation features include skeletal rigs, blending, morph targets, and animation imports from glTF files. Bevy UI uses an ECS-driven, flex-box layout and can be composed in code or with the Bevy Scene format.

Scenes can be saved and loaded, and changes to scene files can be applied while an app is running. Hot reloading for assets currently covers scenes, textures, and meshes. Audio files can be loaded and played as assets. Bevy targets Windows, macOS, Linux, web, iOS, and Android; it is available as a library on crates.io and can be added to a Rust project with cargo add bevy. Users choose the MIT or Apache 2.0 license, with no license fees or sales cuts. The Bevy Foundation is a Washington State nonprofit supporting the engine. Bevy remains in development, with possible missing features, sparse documentation, and breaking API changes roughly every three months.

Who it suits

Bevy suits Rust developers building games or other graphical applications who want an open-source engine targeting desktop, web, and mobile platforms. It may also fit teams that value a custom ECS and are prepared to work with a project whose features, documentation, and APIs are still evolving.
