Back Your Stack!

We started Back Your Stack to help companies discover the open source projects they are using that need financial support. Our goal is to arm champions in each company with a tool to help them make the case internally for supporting the projects they depend on. We want to make it easy for you to review your company’s open source stack and provide a way for sustaining it.


Shiny new look!

We relaunched our homepage to better reflect what we do and how you can join this movement. Check out the sections for Open Collective Chapters and Hosts, how to become a Sponsor or a backer and swing by the most active collectives!
