RakuOS is an immutable Linux distribution based on Fedora, with a choice of KDE Plasma, GNOME and COSMIC desktops. It combines an immutable, read-only base system with the full package flexibility of a traditional Linux distribution. While the core system updates atomically and can be instantly rolled back, the system's persistent overlay lets the user install any package, either through the dnf package manager or the distribution's own software center called RakuOS Software. Installation of Flatpak packages is also supported. RakuOS uses the performance-optimised CachyOS Linux kernel and also includes a graphical CPU scheduling utility to fine-tune the system for gaming, workloads or power efficiency use cases.
To compare the software in this project to the software available in other distributions, please see our Compare Packages page.
Notes: In case where multiple versions of a package are shipped with a distribution, only the default version appears in the table. For indication about the GNOME version, please check the "nautilus" and "gnome-shell" packages. The Apache web server is listed as "httpd" and the Linux kernel is listed as "linux". The KDE desktop is represented by the "plasma-desktop" package and the Xfce desktop by the "xfdesktop" package.
Colour scheme:green text = latest stable version, red text = development or beta version. The function determining beta versions is not 100% reliable due to a wide variety of versioning schemes.

Been using various Ublue distros over the last couple years, but settled on Bazzite last year, just moved one of my machines wholesale to RakuOS, there's ALOT of improvement there over the other ublues. The RakuOS Software app is especially interesting, lots of settings there in the gui. It's essentially the AIO for package management and looking forward to seeing how it evolves, but as is now pretty damn good.
Support is solid; had some minor hiccups, but Matrix chat support was pretty quick to sort it out and now a new build will come to address those issues for others to not have to deal with them.
For those on an existing Ublue distro, rebasing will keep your data, BUT will erase any overlays, flatpak, distrobox configs and such, honestly not a HUGE deal, just something to make note of before moving over (I think the dev is working on a means to relink all that).
The more current kernel, the more cohesive UI experience with a setup, welcome app, etc, is already a pretty refined experience vs using ujust and such (which is not bad, just less intimidating for new users to Linux in general).
This distro even in these earlier stages is shaping up to be a more evolved immutable distro. This is not a knock on the others out there, but this one already feels more newbie-friendly for those coming on. For the distrohopper I'd recommend this; only be mindful you'll need to reinstall overlays and flatpaks (data preserved, just need to reintegrate), if coming from another distro, tho the Dev team has stated they'd address that at some point so all that is relinked, reinstalled, for now the manual way is the way to go for reinstalling/relinking with existing data (and there are ways to do all that).
Steam worked great, it installed, and just had to log back in and all my existing ondisk library games were there and ready to roll.
The CachyOS kernel is a nice to have there. Up to date and such.
Using the KDE variant.
This is a happy medium between immutability and flexibility in packages.

As a user of a custom Fedora Kinoite image for some time, I am very impressed with RakuOS. I am running it on a laptop at the moment.
RakuOS is unique in it's approach of allowing users of Fedora's atomic spins to easily install packages with dnf (or rakuos install) -- something that Fedora atomic distros usually don't allow (instead the user has to manually keep track of their rpm-ostree overlays). That is a breath of fresh air that allows users to install packages without having to use Flatpaks, distroboxes, brew etc. (of course you can still do all that if you wish). It takes away the need for someone to develop their own custom base image using Blue Build type services. Instead you have complete freedom to decide what you want on your base system using familiar package managers, with the benefits of image rollback and automatic package updates.
RakuOS comes with a nicely designed RakuOS Software application that allows you to set what base image you want ("main", more up to date "staging", and very nicely for those of us that like to be on the bleeding edge -- a rawhide version). The RakuOS update checker can be set for different frequencies and includes overlay packages, Flatpak updates and Appimage update. In addition the usual package search and install is provided by the GUI.
There is also a nice RakuOS Welcome app that will set up Gaming, Virtualization and AI (with Ollama).
I like that the developer allows users to shape their system. The flagship desktop is the KDE. Gnome and Cosmic are also offered. Cosmic is listed as "Beta", but it's what I've been using and works flawlessly. The one decision the developer has made for users is using the CachyOS kernel instead of the Fedora Kernel. For the NVIDIA version, this requires a DKMS build of the proprietary NVIDIA drivers. This is something gamers will probably appreciate and the CachyOS kernel is well regarded.
I didn't give it a 10 simply because this OS is in early development and no doubt there is some room for improvement (online documentation will undoubtedly flesh out, for example), but honestly it's a really good OS in it's current state.
