Software, electronics and automation – lean, self-hosted, built to last.

Low-Resource · Self-Hosted · No Vendor Lock-in

PRINCIPLES
Lean

No dependency that hasn't earned its place. No framework that creates more problems than it solves.

Self-Hosted

What runs on a small server needs no cloud contract. Control stays with the operator.

Lasting

Built to last. Maintainability and readability over trends and technical activism.
