People. Processing is a community effort led by a small group of volunteers.

Lead Developers
Ben Fry and Casey Reas started Processing in Spring 2001 and continue to obsessively work on it. In 2012, they started the Processing Foundation along with Dan Shiffman, who formally joined as a third project lead.

Libraries, Tools
The core Processing software is augmented by libraries and tools contributed through the community. These inventive extensions are a bright future for the project. We have a list of Contributed Libraries and Contributed Tools posted online. These contributions can't be underestimated. For example, see how Karsten Schmidt (London) has transformed Processing through the toxiclibs library and how Damien Di Fede (Austin) has extended the project into programming sound through his minim library.

Processing.js is an autonomous sister project to Processing. It is run by David Humphrey, Jon Buckley, and Mike Kamermans. It was started by John Resig and nurtured by Al MacDonald before it found a home at Seneca College’s Centre for Development of Open Technology (CDOT).
