XigmaNAS review
A free ZFS NAS operating system with virtualization and extensive file services.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
XigmaNAS is a free, open-source network-attached storage operating system for home users and small businesses. It runs on user-provided hardware and provides web-based administration for storage, networking, access control, file sharing, monitoring, and related services. Its storage foundation includes ZFS pools, software RAID, point-in-time snapshots with retention settings, and Unix/POSIX users, groups, and permissions. LiveCD and LiveUSB installation options support embedded and full installation modes.
For storage and virtualization, XigmaNAS covers more than basic file sharing. It supports SMB/CIFS, NFS, FTP, SSH, iSCSI, and rsync, giving administrators several ways to expose files, block storage, and transfer services across a network. VirtualBox-based virtual machine hosting adds a virtualization option, while FreeBSD jails and container management extensions support additional workloads. These capabilities make it a strong fit for buyers who want ZFS protection and virtualization in one self-hosted system.
The main trade-off is focus. XigmaNAS is designed around a web-managed, self-hosted NAS rather than a broader multi-platform service, and it does not include AI features. Installation and operation also depend on hardware supplied and managed by the buyer. Choose XigmaNAS if free, open-source storage with ZFS, snapshots, permissions, file protocols, and virtualization matches your environment. Buyers seeking a wider platform ecosystem or AI-assisted functionality should consider an alternative.
