Bevy Engine Features Getting Started Learn News Community Foundation Assets Examples Donate A refreshingly simple data-driven game engine built in Rust Free and Open Source Forever! Get StartedData DrivenAll engine and game logic uses Bevy ECS, a custom Entity Component System Fast: Massively Parallel and Cache-Friendly. The fastest ECS according to some benchmarksSimple: Components are Rust structs, Systems are Rust functionsCapable: Queries, Global Resources, Local Resources, Change Detection, Lock-Free Parallel Scheduler2D RendererRender real-time 2D graphics for games and apps Features: sprite sheets, dynamic texture atlases, cameras, textures, and materialsExtensible: custom shaders, materials, and render pipelinesCommon Core: builds on top of Bevy's Render Graph3D RendererA modern and flexible 3D renderer Features: lights, shadows, cameras, meshes, textures, materials, gltf loadingExtensible: custom shaders, materials, and render pipelinesCommon Core: built on top of Bevy's Render GraphRender GraphCompose custom render pipelines using a graph structure Parallel: Render Graphs are automatically rendered in parallelModular: Build composable and reusable render logic using Render Graph nodesBackend Agnostic: Not tied to a specific graphics APIAnimationA capable animation systemSkeletal rig animation driven by an ECS-based joint APIPlay multiple animations at the same time by smoothly blending between themUse blend shapes / morph targets to animate vertices directlyImport animations from GLTF filesCross PlatformSupport for all major platforms: Windows, MacOS, Linux, Web, iOS, AndroidBevy UIA custom ECS-driven UI framework built specifically for Bevy Built directly on top of Bevy's ECS, Renderer, and Scene pluginsCompose UIs dynamically in code or declaratively using the Bevy Scene formatUse a familiar "flex box" model to layout your UIsScenesCreate, save, and load ECS worlds using Bevy's Scene system Loading: Loading scenes preserves entity IDs (useful for save games)Instancing: Instancing creates linked duplicates of scenes with new entity IDsHot Reloading: Changes to scene files are automatically applied to running appsSoundLoad audio files and play them on demand Load audio files as AssetsPlay audio Assets using Audio entitiesHot ReloadingGet instant feedback on your changes without app restarts or recompiles Asset changes are immediately reflected in running Bevy appsYou can currently hot-reload scenes, textures, and meshesAny asset type can be integratedProductive Compile TimesGame development is an iterative process. You can't afford to wait for compiles With Bevy you can expect 0.8-3.0 seconds with the "fast compiles" configurationCompare that to other popular Rust game engines, which can take over 30 seconds to compile a single newline insertion!Free and Open SourceAn engine made by and for the developer community 100% free.
