Maintainer activity

1 person did triage or write work on this repository in the last 12 months.

Counts unlabeled, assigned, unassigned, milestoned, demilestoned, locked, unlocked over the last 12 months. These are issue and pull request events that require triage or write permission. Commits and code review are not counted. labeled and renamed are excluded because GitHub issue forms record the issue author as the actor. Figures from October 11, 2026. This count is not comparable across projects: each project's automation decides which of these events a person emits.

How this project is maintained

Around half of the issues opened in the past year never receive a reply. 100% of open issues come from outside the core team, so the backlog reflects real-world use rather than internal planning. 67% of tracked open issues have had no activity in three months, so the open count overstates what is actively being worked. Only 11% of issues opened in the past year have been closed.

Detailed Description

ZimaOS is a lightweight operating system for network-attached storage devices that runs on Zima series hardware and generic x86-64 systems with UEFI support.

ZimaOS addresses the need for a streamlined, efficient NAS operating system by building on CasaOS with improvements in hardware compatibility and update mechanisms. It is constructed using Buildroot and emphasizes minimal resource consumption and I/O efficiency. The system includes stable over-the-air update functionality alongside offline update capabilities, and provides enhanced disk management features compared to its predecessor.

Organizations and individuals running Zima hardware such as ZimaBoard, ZimaBoard2, ZimaBlade, or ZimaCube should choose this system for native optimization. It also suits users with generic x86-64 systems like Intel NUC who want a lightweight NAS operating system. The README positions ZimaOS as an evolution of CasaOS with specific improvements in hardware support and update experience, though it does not provide detailed comparisons to other NAS operating systems.

The project is maintained as a public evaluation program with active discussion channels in the community forum. Installation is straightforward, requiring UEFI boot mode and using standard USB imaging tools. The tool supports installation on virtualization platforms such as Proxmox, extending its deployment flexibility beyond physical hardware.
