Dragonfly is an interactive fiction game engine. It allows you to create and play interactive fiction games in your browser.

Simple development. For this, Dragonfly uses DFML: a simple and easy-to-understand language (JavaScript is practically not required).

No compilation, no engines, no virtual machines. It runs directly in the browser. You don’t need any special program to run your game. You can easily place it on any website.
