For anything to grow, you need three things:
Heat means work.
Upstream contributions, bug fixes, designs, docs--the rigorous work that drives the community.
Light means visibility.
For the projects, contributions, opportunities, challenges, and people that impact the community.
Love means culture and support.
Why we care. How we work. Actions that grow the community.
Twitter has been built on open source since the beginning. Openness is part of our DNA. The projects you see here were born at Twitter, and patches are always welcome!View All Projects
