OpenFL is an open-source Haxe framework implementing the classic Flash/AIR APIs for building games and creative applications. A single codebase compiles to native C++, JavaScript/WebGL, Neko, HashLink, or AIR across desktop, mobile, web, and console targets.
Use cases
- build a cross-platform 2d game with one codebase
- port an old flash actionscript game to html5
- make a mobile app with flash-like display list apis
- develop a game for ios android and web at once
- use haxeflixel or starling to build a game
- create gpu-accelerated web graphics with webgl
- migrate adobe air app to open source stack
When to choose
- you know ActionScript 3 or the Flash API and want a modern open-source successor
- you need one Haxe codebase deployed to native desktop, mobile, and HTML5
- you want to build on engines like HaxeFlixel, HaxePunk, Starling, or Away3D
When to avoid
- you need a mainstream ecosystem with large hiring pools like Unity or Godot
- you want pure JavaScript/TypeScript web development without Haxe
- your project needs cutting-edge 3D rendering beyond the Stage 3D pipeline
