Simpler tools for
a better world

Software now runs nearly everything, and the tools used to build it have grown harder to use every year. Dashboards sprawl. Settings multiply. The people building the world’s products spend more of their day working around their tools than working with them.

Califa was founded to change that. The company believes that when technical tools become simple, everything downstream improves. Companies ship faster. Teams keep their best people. The software that reaches the public respects the time of the people using it. By simplifying the tools that build the world, Califa makes the world a better place.

  • Distributed by default.

  • Supported by friends who work at

  • “Califa has been steadily improving.”
