## What it is
Ebitengine (formerly Ebiten) is an open-source 2D game engine for Go with a simple image-based drawing API. It supports desktop, mobile, web (WebAssembly), and console targets with GPU-accelerated batched rendering, input handling, and audio playback.

## Use cases
- build a 2d game in go
- deploy a go game to webassembly
- make a mobile game with golang
- 2d game engine with simple api
- render sprites and text in go
- play ogg mp3 wav audio in a go game
- handle keyboard mouse and gamepad input in go

## When to choose
- you want to write 2D games in pure Go with a minimal API
- you need one codebase targeting desktop, mobile, and web
- you want GPU-accelerated rendering with automatic batching and texture atlases
- you prefer a production-proven engine used in shipped commercial games

## When to avoid
- you need 3D rendering or a full editor-driven engine like Unity or Godot
- you need a large asset pipeline, physics engine, or built-in editor
- you require platforms beyond those officially supported (e.g., consoles other than Switch/Xbox)

## Facets
- artifact type: framework
- maturity: stable
- function: game-engine, graphics, audio-processing, image-processing
- domain: cross-platform
- platform: go, windows, wasm, browser, cross-platform
- tags: 2d-graphics, gamedev, shaders, gamepads, texture-atlas, nintendo-switch, game-development, macos, linux, android, ios
