Edge Collective

Accessible infrastructure for communities living at ‘the edge'.

Edge Collective is a distributed research, teaching, and facilitation cooperative working to help individuals and communities increase the capacity of their vital food, water, energy, and communications infrastructure to adapt to challenging environments.

All of the research, designs, and code that we produce are freely available in our archives as Free and Open Source / Creative Commons. (You can read more about our philosophy here.)

We support our work through donations and via 'pay-as-you-can' arrangements. Cheers!
