Ruffle detects all existing Flash content on a website and automatically processes it in the Ruffle Player to ensure smooth updates for websites that still rely on Flash content. The emulator is able to work in all modern operating systems (Microsoft Windows, Mac OS X, Linux) as a standalone desktop application, as well as in all popular web browsers (Mozilla Firefox, Safari, Google Chrome, Microsoft Edge, Brave, Opera, Vivaldi) thanks to using WebAssembly. With this application, you can easily play Flash content as if the Flash is still installed. Ruffle is a free Adobe Flash Player emulator written in the Rust programming language.
