XigmaNAS is an open-source network-attached storage (NAS) server software with a dedicated management web interface. It is a continuation of the original FreeNAS code, which was developed between 2005 and late 2011. It was released under the name NAS4Free on 22 March 2012.^[1][2] The name was changed to XigmaNAS in July 2018. On SourceForge, it was elected "'Community Choice' Project of the Month" twice, in August 2015 and March 2017.^[3]

XigmaNAS is an embedded open-source NAS software distribution based on the latest release of FreeBSD.^[4][3] It is free software under the terms of the Simplified BSD license.^[5] It was developed from the original FreeNAS 7 code and updated to work with current FreeBSD releases^[1] while preserving FreeNAS's original m0n0wall/PHP architecture and introducing experimental support for the ARM architecture.^[6]

XigmaNAS supports sharing across Windows, Apple, and UNIX-like systems. It includes ZFS v5000, Software RAID (0,1,5), disk encryption, S.M.A.R.T., and email reports etc., with the following protocols: SMB, Samba Active Directory Domain Controller AD, FTP, NFS, TFTP, AFP, rsync, Unison (file synchronizer), iSCSI (initiator and target), HAST, CARP, Bridge, UPnP, and BitTorrent. All of this is configurable through its web interface.

XigmaNAS is installable on almost any boot medium including LiveCD, both for x86-64 and x86-32 computer platforms up to version 10.3.^[9] As of version 11.0, XigmaNAS no longer supports x86-32, but version 10.3 is still getting updates.^[10] XigmaNAS can be installed on Compact Flash, USB flash drives, SSD, hard drives or other bootable devices, and supports advanced formatted drives using 4 kB sectors. The software distribution is currently distributed in ISO image (.iso, approximately 370 MB), USB flash drive image (.img, approximately 320 MB) format, and in source form.

The original FreeNAS project derives from m0n0wall.^[11]

The FreeNAS 0.7 branch was end-of-life'd in late 2011 after the FreeNAS name was legally acquired by iXsystems, Inc. Starting with version 8.x, new iXsystems developers rewrote FreeNAS. Legacy FreeNAS 0.7 was no longer available for download.

The legacy FreeNAS 0.7 code was unable to be developed any longer under the same name, and a name change was necessary. The founder of FreeNAS (Olivier Cochard-Labbé) donated the original FreeNAS source code to the NAS4Free project. With the support of the former developers, namely Daisuke Aoyama and Michael Zoon, it carries on the original FreeNAS code base. FreeNAS 8.x.y and up is a software fork of the original FreeNAS with a new rewritten code base, continuing the old branded name.^[1] In 2018, the project applied for the XigmaNAS trademark to protect the brand^[12] prior to the release of v11.2.

Further readings prior to 2012 are referring to the legacy FreeNAS .07 precursor branch.
