Floem is a native Rust UI library with fine-grained reactivity, inspired by Xilem, Leptos, and rui. It provides a declarative, ergonomic API for building high-performance cross-platform desktop applications with GPU or CPU rendering.

Use cases

  • build a native desktop app in Rust
  • create a reactive GUI with fine-grained signals
  • build a cross-platform UI toolkit application
  • write a performant declarative UI in Rust
  • build custom widgets with flexbox and grid layout
  • create animated UI transitions in a Rust app

When to choose

  • you want a native Rust GUI with reactive signals and high performance
  • you need cross-platform desktop support (Windows, macOS, Linux) with GPU or CPU rendering
  • you prefer a declarative, ergonomic API inspired by Leptos-style reactivity
  • you need Flexbox/Grid layout and customizable, themeable widgets

When to avoid

  • you need a fully stable, v1-guaranteed API — the project is still maturing with occasional breaking changes
  • you want to target mobile or web platforms
  • you need a large ecosystem of third-party widgets and mature tooling
  • you prefer an immediate-mode or imperative UI model
