## What it is
Relm is an idiomatic, asynchronous, GTK+-based GUI library for Rust, inspired by the Elm architecture. It lets developers build desktop applications using an Elm-style model-update-view pattern on top of GTK.

## Use cases
- build a desktop GUI app in Rust
- write GTK applications using the Elm architecture
- create cross-platform desktop software with Rust
- manage GUI state with a model-update-view pattern
- build async GTK apps without manual callback wiring

## When to choose
- you want to build a native desktop GUI in Rust with GTK
- you prefer the Elm model-update-view architecture for UI state
- you want an idiomatic, async-friendly alternative to raw gtk-rs callbacks

## When to avoid
- you need a web or mobile UI rather than a native desktop app
- you prefer Qt or another non-GTK toolkit
- you need a very mature ecosystem with extensive widget documentation beyond GTK

## Facets
- artifact type: library
- maturity: active
- function: gui, ui-components, state-management
- domain: desktop-applications, cross-platform, developer-tools
- platform: windows, rust, cross-platform
- tags: gtk, elm-architecture, mvu, desktop-gui, async, linux, macos
