UI Toolkits/

Crates that offer fully-featured UI toolkits suitable for real application development.

Primarily, this category aims to include only Rust-driven toolkits intended to be used to implement standard desktop and mobile applications in Rust itself. This intentionally excludes toolkits that offer bridges or bindings to other non-Rust UI toolkits, such as Qt, GTK, Electron, Flutter, React, FLTK, etc. This category also excludes toolkits that are primarily for games, such as Bevy.

Other GUI-related crates can be found at https://areweguiyet.com/.

Slint

Slint is a native GUI toolkit with a declarative language for embedded, desktop, and mobile applications.

  • Stable 1.x API
  • Uses an easy to learn Domain specific language
  • Native look and feel with a built-in widget set
  • Live preview and editor integration
  • Support for AccessKit
  • Focus on small footprint and performance
  • Triple-licensed: GPL, a royalty-free license for desktop/mobile, and a commercial license for proprietary embedded use

egui

Well suited for applications with complex visualizations, multimedia, or those that directly use an OpenGL context.

Inspired by Dear ImGui; for bindings to Dear ImGui see imgui.

Notes:

  • Immediate-mode style API, which comes with advantages and disadvantages
  • Relatively simple to integrate with game engines and other GUI frameworks
  • Support for AccessKit and a built-in screen reader
  • Pleasant appearance out of the box
  • Does not support platform-native look and feel
