Ruffle is an Adobe Flash Player emulator written in the Rust programming language. Ruffle targets both the desktop and the web using WebAssembly.

Ruffle is in the proof-of-concept stage and can currently run early Flash animations. ActionScript support is still forthcoming; for more info, read the project roadmap.

Follow the official guide to install Rust for your platform.

• cargo run --package=ruffle_desktop -- test.swf

• Install Node.js
• Install wasm-pack

• cd web/demo
• npm install
• npm run serve
• Load indicated page in browser (usually http://localhost:8080)

• cd web
• wasm-pack build

If you have a collection of "real world" SWFs to test against, the scanner may be used to benchmark ruffle's parsing capabilities. Provided with a folder and an output filename, it will attempt to read all of the flash files and report on the success of such a task.

• cargo run --package=ruffle_scanner -- folder/with/swfs/ results.csv

• core contains the core emulator and common code
• desktop contains the desktop client (uses glium)
• web contains the web client (uses wasm-bindgen)
• scanner contains a utility to bulk parse swf files

You can support the development of Ruffle via GitHub Sponsors. Your sponsorship will help to ensure the accessibility of Flash content for the future. Thank you!
