Welcome to join the public evaluation program of ZimaOS. ZimaOS is evolved from CasaOS, and we have built a release version of ZimaOS for better hardware compatibility and update experience. It will perfectly adapt to the Zima series hardware and also be compatible with x86-64 systems with UEFI.

It is built using Buildroot and has stable OTA update functionality. Based on CasaOS, we have built a series of new applications. You can find the specific differences between it and CasaOS from the table below:
