TrueNAS is the world’s most popular Open Source storage operating system and is the most efficient solution for managing and sharing data over a network. It is the simplest way to create a safe, secure, centralized, and easily accessible place for your data. TrueNAS Open Storage provides unified storage for file, block, object, and application data.

TrueNAS can be installed on virtually any hardware platform and is suitable for home, business, and enterprise applications. There are three editions of TrueNAS that enable a broad range of applications while sharing common management tools and enabling data transfers:


TrueNAS CORE is free and Open Source and is the successor to the wildly popular FreeNAS. It runs on virtually any x86_64 system and provides a broad set of features for many users. Plugin applications like Plex, NextCloud, and Asigra allow the functionality of a system to be customized for many use cases.


TrueNAS Enterprise is provided as part of an iXsystems hardware purchase. Systems can have either single or dual controllers to enable High Availability (HA). It can also be provided with Enterprise-grade support from iXsystems.

The current major version of CORE/Enterprise is 13.0. The content in this section documents this version. Documentation for previous major versions is available in the Documentation Archive. This includes the latest 12.0 release notes.
