Relm4 is an idiomatic Rust GUI library inspired by the Elm architecture and built on top of gtk4-rs and GTK4/libadwaita. It provides a declarative, component-based model for building truly native cross-platform desktop applications with built-in async support.

Use cases

• build a native desktop app in rust
• create a cross-platform gui application
• write gtk4 apps with an elm-style architecture
• build a gnome/libadwaita application in rust
• declarative ui toolkit for rust
• native gui without a web runtime

When to choose

• you want truly native GTK4 apps in Rust with no web runtime
• you prefer the Elm model-view-update pattern for UI state
• you target Linux/GNOME primarily but also macOS and Windows
• you want strong documentation and reusable components

When to avoid

• you need a mobile or web frontend
• you want a non-GTK look or Flutter/Qt-style widgets
• your team has no Rust experience and wants a simpler language
