Open source is an essential tool for the tech community, providing open and accessible platforms for accomplishing everything from building websites to artificial intelligence. Yet the drivers behind open source are often individuals, and their commitments of time, energy and inspiration are truly an act of personal philanthropy; many players in the movement do it on their own time. 

 We talked about how open source can accelerate social good last month in SSIR, and increasingly, open source is critical for nonprofits and individuals who may not have the funds to build out software from scratch or license expensive and cumbersome enterprise software. 

 At the Case Foundation, we’re committed to contributing to the open source community and recognizing others who are doing so too. These 18 people have made a personal commitment to sharing their digital work with the online community. Learn more about them and how you can follow their work on Twitter below.
