We build infrastructure tooling.
Focused tools for infrastructure work that should be repeatable, on hardware you own.
ProvisionBerry
A fresh start for every Pi, a room at a time.
Re-image, identify and configure rooms full of Raspberry Pis from one repeatable run. Built for universities, schools, teaching labs and device teams.
- Reset a whole lab without rebuilding each card by hand
- Keep the right setup for every class, room and project
- Runs on your own network, with your images and playbooks
Casefile
A document for every resource, kept current.
A Terraform provider that documents each change as you make it, on hardware you own.
- A living document for every resource
- Written during the apply that changed it
- A local model on your own hardware
