## What it is
Gio is a Go library for writing cross-platform immediate mode GUIs, supporting Linux, macOS, Windows, Android, iOS, FreeBSD, OpenBSD, and WebAssembly. It uses GPU-based vector rendering with minimal dependencies on platform libraries for windowing, input, and drawing.

## Use cases
- build a cross-platform desktop app in Go
- write an Android app in pure Go
- create an iOS application with Go
- build a GUI that runs in the browser via WebAssembly
- make a fluid immediate-mode UI with GPU vector rendering
- package a Go GUI program as a native mobile app
- build a lightweight GUI with few dependencies

## When to choose
- you want a single Go codebase targeting desktop, mobile, and web
- you prefer immediate mode UI over retained widget trees
- you need efficient GPU-based vector rendering with resolution independence
- you want minimal dependencies beyond platform window/input libraries

## When to avoid
- you need a large ecosystem of prebuilt widgets and mature tooling like Qt or Electron
- your team is not working in Go
- you require pre-1.0 API stability, since breaking changes still occur in minor versions
- you need deep native platform integration beyond what Gio exposes

## Facets
- artifact type: library
- maturity: active
- function: gui, graphics, ui-components, animation
- domain: cross-platform, graphics, desktop-applications, mobile-development, web-development
- platform: windows, wasm, go, cross-platform, bsd
- tags: immediate-mode, gpu-rendering, vector-graphics, golang, gui-framework, linux, macos, android, ios
