Since 2013, the PhET sims have been developed in HTML5, which is the language we recommend.

HTML5 Source Code

The PhET HTML5 and Javascript source code lives on the PhET GitHub page. For instructions on getting your machine set up to develop simulations using the PhET libraries, take a look at our PhET Development Overview document:
