How we work
Ideas, built into something usable.
Too many good ideas die in a repo nobody ships. We carry them all the way to tools people actually use.

Products
Open tools built with the people who will use them — clinics, co-ops, city offices, small NGOs. Free forever, no tier above them.
- Six tools in active use across 34 countries
- Apache-2.0, self-hostable, no lock-in
- Built with the people who use them, not for them
