Call for Code

Now in its third year, the Call for Code initiative is the largest technical challenge of its kind. The 2020 Call for Code Global Challenge asks the world’s developers to build solutions for COVID-19 and climate change. The world is facing unprecedented, interconnected challenges, and we believe technology can help.

Our Initiative

The Call for Code Global Challenge — created by David Clark Cause and supported by Founding Partner IBM and Charitable Partner United Nations Human Rights — invites developers and problem solvers around the world to build solutions that fight back against the most pressing issues of our time. Together with The Linux Foundation, top solutions are open sourced and deployed.
