About

p5.js is built and organized to prioritize accessibility, inclusivity, community, and joy. Similar to sketching, p5.js has a full set of tools to draw. It also supports creating audio-visual, interactive, experimental, and generative works for the web. p5.js enables thinking of a web page as your sketch. p5.js is accessible in multiple languages and has an expansive documentation with visual examples. You can find tutorials on the p5.js website and start coding right now in the p5.js web editor. You can extend p5.js with many community-created libraries that bring different capabilities. Its community provides endless inspiration and support for creators.

p5.js encourages iterative and exploratory code for creative expression. Its friendly, diverse community shares art, code, and learning resources to help elevate all voices. We share our values in open source and access for all, to learn, create, imagine, design, share and code freely.

Community

The p5.js community shares an interest in exploring the creation of art and design with technology. We are a community of, and in solidarity with, people from every gender identity and expression, sexual orientation, race, ethnicity, language, neuro-type, size, disability, class, caste, religion, culture, subculture, immigration status, age, skill level, occupation, and background. We stand in solidarity with justice and liberation movements. We work to acknowledge, dismantle, and prevent barriers to access p5.js code and the p5.js community.

p5.js was created by Lauren Lee McCarthy in 2013 as a new interpretation of Processing for the context of the web. Since then we have allowed ourselves space to deviate and grow, while drawing inspiration from Processing and our shared community. p5.js is sustained by a community of contributors, with support from the Processing Foundation. p5.js follows a rotating leadership model started in 2020.
