## What it is
Skia is Google's open source 2D graphics library providing common APIs for drawing text, geometries, and images across hardware and software platforms. It serves as the graphics engine for Chrome, ChromeOS, Android, Flutter, and Firefox.

## Use cases
- render 2D shapes and text in a C++ application
- build a cross-platform custom UI toolkit with hardware-accelerated drawing
- draw images and bezier curves on canvas across mobile and desktop
- embed a graphics engine in a browser or app framework
- render PDFs or rasterize vector graphics

## When to choose
- you need a battle-tested, high-performance 2D rendering engine in C++
- you want consistent drawing APIs across Windows, macOS, Linux, iOS, and Android
- you are building a UI framework, browser, or design tool that needs GPU-accelerated 2D graphics

## When to avoid
- you need 3D rendering rather than 2D drawing
- you want a high-level ready-made UI widget toolkit rather than a drawing library
- your project is in a language other than C++ without bindings

## Facets
- artifact type: library
- maturity: stable
- function: graphics, image-processing, gui
- domain: graphics, cross-platform, developer-tools
- platform: cpp, cross-platform, windows
- tags: 2d-graphics, rendering-engine, text-rendering, canvas, gpu-accelerated, chrome, flutter, macos, linux, android, ios
