Success Stories

Umbrel Pro device

Umbrel

Umbrel is a personal home cloud platform that lets anyone self-host their files, media, and applications with tens of thousands of installations worldwide. Umbrel chose Rugix for umbrelOS, powering devices like the recently launched Umbrel Pro, their premium home cloud server. Rugix was chosen for its robustness, builtin state management with clean factory resets, and highly efficient delta updates.

eChecker test bench with e-bike

eChecker

eChecker builds test benches for e-bikes, drive units, and e-scooters used by test institutes and manufacturers worldwide. Each test bench is controlled by an embedded Linux system, powered by and updated through Rugix. Rugix enabled eChecker to easily build custom system images and reliably deliver over-the-air software updates to test benches deployed across customer sites.

BatteryBrain device

BatteryBrain

"At Enmo, we use Rugix for our product, BatteryBrain—a device optimizing battery systems based on spot prices, battery health, production inputs, and electricity markets. Rugix has been essential in bringing BatteryBrain to a production-ready state as quickly and efficiently as possible. It has simplified the creation of a custom Raspberry Pi image and enabled seamless over-the-air (OTA) updates."
