Build solutions that fight back.

In a very short period of time, COVID-19 has brought modern life to a screeching halt, disrupting our healthcare, education and economic systems. But we can fight back – with technology.

The 2020 Call for Code Global Challenge has expanded to take on COVID-19 in addition to climate change.

Created by David Clark Cause with Founding Partner IBM, and in partnership with the United Nations Human Rights and The Linux Foundation, Call for Code is the largest tech-for-good challenge of its kind.

Innovators and problem solvers: join us to create open source solutions that make an immediate and lasting impact. Now, more than ever, is the time to use technology for good.
