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
