CasaOS is still recommended constantly as the easy way into running a home server. It is worth knowing, before you follow that advice, that its makers have moved on.

What the maker says now

Visit the CasaOS site and the message is not subtle. It tells you that CasaOS has been upgraded to ZimaOS, and directs you to that instead.

That is the maker’s own page doing the redirecting, not a rumour or a forum theory.

What the code says

The CasaOS releases page tells the same story in a different way. The most recent published release is v0.4.15, from 19 December 2024.

Checked on 21 September 2026, that is more than 20 months without a release.

For most software that would be a warning sign. For software whose job is to sit permanently on a machine exposed to your home network, handling your files, it is a more serious one. Security fixes arrive in releases. No releases means no fixes arriving through the front door.

What this means if you are already running it

Your setup has not broken and will not break tomorrow. CasaOS still works, and nothing about the announcement stops a running system from running.

But you are now maintaining something the maker is not. Two practical consequences:

The underlying system still gets updates, and CasaOS does not. CasaOS is not a complete operating system. It installs on top of an existing Linux, which per its own repository is officially tested on Debian 12, Ubuntu Server 20.04 and Raspberry Pi OS. You can keep patching that base normally. The CasaOS layer sitting on top is the part that has stopped moving.

Anything it does not already support, it never will. New container features, new hardware, changes in how the apps you rely on are packaged: none of that is coming.

Should you move

It depends entirely on what the machine does, and the honest answer is not the same for everyone.

If it is a media box or a toy, there is no emergency. Keep the base operating system patched, do not expose it to the internet, and move when it suits you rather than in a hurry.

If it holds anything you would be upset to lose, treat this as a prompt rather than a crisis. Not because CasaOS will fail, but because an unmaintained management layer is a slow-accumulating risk on a machine whose whole purpose is keeping things safe.

If you have not installed anything yet, this one is easy. Do not start on a project its own maker has stopped developing. Pick something with a live release schedule, and you will find the choice is a short list.

The wider point

This is the failure mode worth understanding in home server software generally. Projects rarely announce that they are finished. They get quietly replaced by the same team’s next thing, the website changes, and the old recommendation carries on circulating in articles and forum replies for years afterwards.

The check takes thirty seconds and works for anything: open the project’s releases page and look at the date on the newest one. A project shipping every few weeks is alive. A project that last shipped in 2024 is telling you something, whatever the article that recommended it says.
