Who builds p5.js and Processing?
p5.js (2013–present) and Processing Java (2001–present) have been maintained by volunteer contributors, who support the projects in critical ways. Over the past quarter-century, nearly a thousand contributors have built Processing Java and p5.js together.
However, free time is a privilege not equally available to all, and without funding open source work, biases in time inequality show up in OSS communities, too. To acknowledge time inequality, Processing Foundation offers two types of project-based funding to support contributors.
In 2025, Processing Foundation piloted the Developers in Residence Program in p5.js following the 2.0 release, supporting several stewards and developers in welcoming new contributors and improving stability and documentation. Since then, the Developers in Residence Program has been expanded to support more contributors and more projects.
In 2026, Processing Foundation is piloting the Open Source Software Microgrants Program. Although there are only a handful now, the goal is to learn from the pilot and gradually grow this program in a way that best supports the contributor community.
