A project called FreeCORE describes itself as an independently maintained continuation of TrueNAS® CORE, built on the FreeBSD operating system, according to its website, freecore.org.
According to the source, FreeCORE takes the TrueNAS CORE 13.3 codebase and carries it forward as its own operating system, separate from any official TrueNAS CORE development. The project organizes its releases into a “train” of versions: 13.3 is listed as the base version, 15.0 is described as the current version, and 15.1 is listed as the next version in development.
The site states that release 15.0-U1 is considered stable. It also says that systems currently running TrueNAS CORE 13.3 can upgrade directly to 15.0 in place, after which they can continue receiving updates through FreeCORE’s ongoing update train. The website does not provide further detail on what changes or improvements are included between the 13.3 and 15.0 releases beyond referencing a changelog for the 15.0 version.
For installation, FreeCORE provides a guide at freecore.org/install along with downloads, including a disk image labeled FreeCORE-15.0-U1.iso. The site indicates that existing TrueNAS CORE 13.3 systems can perform an in-place upgrade to move onto the FreeCORE train rather than requiring a fresh installation, though the source text does not elaborate on the technical steps involved.
The project lists several channels for community contact and support. These include an IRC channel, #freecore, hosted on the Libera.Chat network, as well as a general contact email address, [email protected]. A separate email address, [email protected], is listed specifically for reporting security-related issues.
In an acknowledgments section, the FreeCORE site credits FreeNAS, TrueNAS CORE, FreeBSD, and OpenZFS. It further notes that original authorship of the underlying code is credited in the license headers of the source files, indicating that FreeCORE builds directly on top of existing open-source components rather than starting from scratch.
The source text does not specify who develops or funds FreeCORE, nor does it detail the reasons for the project’s creation, such as whether it responds to changes in the official TrueNAS CORE roadmap. It also does not provide a timeline for when the 13.3, 15.0, or upcoming 15.1 releases became or will become available. Readers seeking more background on the project’s origins, governance, or relationship to TrueNAS CORE’s original maintainers would need to consult additional sources beyond what is presented on the FreeCORE website.
