FreeCORE describes itself as an independently maintained continuation of TrueNAS CORE 13.3, built on FreeBSD. In the project's own words, it 'carries the TrueNAS CORE 13.3 system forward as an independently maintained operating system on FreeBSD.' It runs its own update train with three named points: 13.3, marked as the base version it forks from; 15.0, marked as current; and 15.1, marked as next. Within the 15.0 line, the specific build FreeCORE-15.0-U1 is stated to be stable, and TrueNAS CORE 13.3 systems are said to be able to upgrade straight to 15.0 in place, then continue receiving updates on FreeCORE's own train rather than staying on TrueNAS CORE's.

For installation, the project provides a guide at freecore.org/install, a downloads page, and the specific ISO file FreeCORE-15.0-U1.iso, alongside separate documentation covering the in-place upgrade path from TrueNAS CORE 13.3. A changelog is linked from the 15.0 entry in the update train, though its contents are not reproduced on the page itself.

The project lists three ways to reach it: an IRC channel, #freecore on Libera.Chat; a general contact address, hello@freecore.org; and a separate address for security reports, security@freecore.org. It closes with a note that original authorship is credited in the source's license headers, without naming a specific license, and a thanks line crediting FreeNAS, TrueNAS CORE, FreeBSD and OpenZFS together, without specifying what each project contributed.

The page does not name any individual or organization behind FreeCORE, and it gives no date for when the project started or when 15.0-U1 was released. It also does not explain why an independently maintained continuation of TrueNAS CORE 13.3 exists in the first place.

Key facts

  • FreeCORE describes itself as an independently maintained continuation of TrueNAS CORE 13.3, built on FreeBSD.
  • The project's update train lists 13.3 as the base version, 15.0 as current, and 15.1 as next; the current build, FreeCORE-15.0-U1, is stated to be stable.
  • TrueNAS CORE 13.3 systems can upgrade in place straight to 15.0, then continue on FreeCORE's own update train.
  • The only listed contacts are an IRC channel, #freecore on Libera.Chat, a general email, hello@freecore.org, and a security email, security@freecore.org; no individual or organization is named as maintainer.
  • The page credits FreeNAS, TrueNAS CORE, FreeBSD and OpenZFS together and says original authorship is credited in the source's license headers, without naming a specific license.

Why it matters

For anyone still running TrueNAS CORE 13.3, FreeCORE offers a concrete next step: an in-place upgrade to a newer base, 15.0, that keeps receiving updates on FreeCORE's own train instead of leaving those installations frozen on the last release. The project describes the result specifically as carrying TrueNAS CORE 13.3 forward as an independently maintained operating system on FreeBSD, continuation rather than a from-scratch rewrite. That the current build, 15.0-U1, is already labelled stable, with a working install guide, a named ISO to download, and documented in-place upgrade steps, means the offer is something a TrueNAS CORE 13.3 administrator could act on today rather than just a stated intention.

Who it affects

This is aimed squarely at people already running TrueNAS CORE 13.3, the version FreeCORE's in-place upgrade path is built for. It also concerns anyone deciding whether to trust an unofficial continuation of that system, described on the page as an independently maintained operating system on FreeBSD: no company or individual is named behind the project, only an IRC channel and two email addresses, one general and one for security reports.

How to use it

The project publishes an install guide at freecore.org/install and a downloads page carrying the current build as the file FreeCORE-15.0-U1.iso. Existing TrueNAS CORE 13.3 systems have a separate, documented path: an in-place upgrade straight to 15.0, after which the system continues on FreeCORE's own update train, currently 13.3 as the base, 15.0 as current, and 15.1 as next. A changelog is linked from the 15.0 entry, though its contents are not shown on the page itself. The page lists three ways to reach the project: the #freecore IRC channel on Libera.Chat, a general contact address, hello@freecore.org, and a separate address for security reports, security@freecore.org.

How solid is it

The only source here is the project's own website, which states plainly that its current build is stable and backs that with a working install guide, a named ISO file and separate in-place upgrade documentation, so the practical claims are at least specific and actionable rather than vague marketing language. But nothing on the page is independently verified: no maintainer, company or individual is named, no date is given for when the project started or when 15.0-U1 shipped, and no specific software license is stated beyond a general note that original authorship is credited in the source's license headers. The changelog linked from the 15.0 entry, which would be the natural place to check what actually changed, is not reproduced on the page itself.

Risks and caveats

Because FreeCORE names no accountable individual or organization, anyone adopting it is trusting an operation reachable only through an IRC channel and two email addresses with an in-place upgrade of an existing TrueNAS CORE 13.3 installation. The page gives no explanation for why an independently maintained continuation of TrueNAS CORE 13.3 exists in the first place. It also credits FreeNAS, TrueNAS CORE, FreeBSD and OpenZFS together in a single thanks line without specifying what each project actually contributed, and it names no specific license, only a general assurance that original authorship is credited in license headers, leaving the exact terms governing use and redistribution unclear from the page alone.
