FreeNAS vs OpenMediaVault

FreeNAS and OpenMediaVault are Open Source network-attached storage operating systems. Both support the SMB, AFP, and NFS sharing protocols, provide a web interface for easy management, and feature a plugin system for installing and managing additional applications.


This Open Source project was started in October 2005 by Olivier Cochard-Labbé and quickly grew as a popular network-attached storage operating system. By September 2009, the development team realized that FreeNAS would need to be completely rewritten in order to incorporate modern features like a plugin architecture, updates to the base system, and a modern User Interface. To carry this out, the original FreeNAS Team transferred the project to iXsystems, who moved from a m0n0wall and PHP-based architecture to one based on FreeBSD’s NanoBSD embedded build system, the Python programming language, the Django CMS, and the Dojo JavaScript toolkit.


OpenMediaVault is the Debian-based successor to the original FreeNAS .7 project. It has been in development since 2009 and is primarily designed to be used in home and small office environments.
