    1. An open source Adobe Flash Player implementation, designed from the ground up to be efficient on current and (hopefully) future hardware.
      Almost everyone thinks Lightspark is a great alternative to Adobe Flash Player.
    2. Ruffle is a Flash Player emulator written in Rust. Ruffle runs natively on all modern operating systems as a standalone application, and on all modern browsers through the use of WebAssembly.

      Ruffle vs Adobe Flash Player opinions
      Almost everyone thinks Ruffle is a great alternative to Adobe Flash Player.
      Ruffle can emulate many Flash games. Ruffle doesn't support ActionScript 3 yet, but it's a good program to keep an eye on.
