Kamma; Open Source and Open Data

Published 23rd April 2020

Both the website you’re reading and the products and services we build make extensive use of open source and open data. As well as being part of our core values, we believe that the creators and contributors of all things open have their efforts recognised and we want to thank everyone involved for their generosity in making and continuing to make their source code, data and fonts available and for making them usable.
