Bevy vs GDevelop

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.

GDevelop is an open-source game engine for creating and publishing games with visual, drag-and-drop tools that do not require code. JavaScript is available for scripting. It supports web, Windows, macOS, Linux, iOS, and Android, with publishing destinations including Google Play, Steam, desktop, web, iOS, and gd.games. Built-in multiplayer services include lobbies, leaderboards, and player accounts. The Free plan costs nothing and includes multiplayer and online services, thousands of Asset Store assets, and Android and desktop publishing once per day. Paid plans include full access to the mobile app, and the Pro plan supports project sharing with teammates. Support options include community resources, professional Discord channels, commercial troubleshooting, and custom development. Education plans provide anonymous student accounts, project access, and classroom resources. Subscriptions can be billed monthly or yearly, with annual savings of up to 40%, and can be canceled at any time; access ends after the paid period.
