## What it is
Ruffle is an open-source Adobe Flash Player emulator written in Rust, targeting desktop and the web via WebAssembly. It supports ActionScript 1, 2, and 3 and ships as desktop apps, browser extensions, and a web player.

## Use cases
- play old flash games and animations in the browser
- run swf files on modern operating systems without flash player
- restore flash content on a website after flash eol
- emulate actionscript 3 content safely
- embed a flash player replacement via npm package

## When to choose
- you need to run or preserve legacy Flash/SWF content
- you want a safe, open-source alternative to Adobe Flash Player
- you need a player that works across desktop, web, and browser extensions

## When to avoid
- you need 100% compatibility with complex ActionScript 3 content, as support is still incomplete
- you need to author new Flash content rather than play existing SWF files

## Facets
- artifact type: application
- maturity: active
- function: simulation, graphics, wasm, gui
