## What it is
egui is an easy-to-use immediate mode GUI library written in pure Rust that runs on the web (via WASM), natively on desktop and mobile, and inside game engines. It ships with eframe, the official framework for building apps targeting Web, Linux, Mac, Windows, and Android.

## Use cases
- build a desktop GUI app in Rust
- create a web app in Rust compiled to WebAssembly
- add debug UI or tooling overlays to a game engine
- prototype interactive tools with minimal boilerplate
- write a cross-platform GUI that runs on web and native
- build simple editor or inspector windows for gamedev

## When to choose
- you want the simplest path to a Rust GUI on web and native
- you prefer immediate mode over retained-mode widget trees
- you need a GUI that integrates into an existing game engine
- you want a pure-Rust, unsafe-free UI library with high portability

## When to avoid
- you need pixel-perfect native platform look-and-feel
- you require complex retained-mode layouts or accessibility-heavy enterprise UIs
- you are building a large document-style application with heavy text editing
- your team prefers declarative/retained GUI paradigms like Qt or GTK

## Facets
- artifact type: library
- maturity: stable

- domain: web-development, cross-platform, developer-tools
- platform: rust, wasm, cross-platform, windows
