## What it is
Ejecta is an open source runtime for iOS and tvOS that provides a fast JavaScript (JavaScriptCore), Canvas 2D, WebGL, and audio environment for HTML5-style applications. It acts like a browser that only displays a canvas element, letting canvas games and apps run as native apps without a WebView.

## Use cases
- run html5 canvas games as native ios apps
- package a javascript game for iphone or ipad without uiwebview
- deploy webgl games to apple tv
- execute javascript with canvas and audio apis natively on ios
- port an impactjs game to the app store
- avoid webview performance overhead for canvas apps

## When to choose
- you have an existing canvas or WebGL game written in JavaScript and want to ship it on iOS or tvOS
- you need better canvas/WebGL performance than a WebView can provide
- your app only needs canvas, audio, and basic JavaScript APIs without full DOM support

## When to avoid
- you need full DOM, CSS, or general web page rendering - use a WebView or a modern alternative like Capacitor
- you target platforms other than iOS/tvOS
- you need a project with active development, recent releases, or a clearly defined license
