All three CapivaraOS distros reach public beta

July 21, 2026

When we opened this blog back in June, the project had no public image at all. A month later, all three distributions in the family have an ISO you can download: Marsh (KDE Plasma), Pup (Xfce) and Snout (GNOME).

All three are beta releases. They are already usable day to day, but still being stabilized — some rough edges may remain, and that is exactly why we would like you to try them and tell us what you find.

Marsh — KDE Plasma

The founding distro of the family, and the most heavily styled: a global menu at the top, a bottom dock and a dark theme by default, for people who like a full, highly customizable desktop. See the Marsh page.

Pup — Xfce

The lightweight option, aimed at computers with at least 4 GB of RAM. It uses Fedora's stock Xfce environment, without heavy decoration, but with the same visual identity as the others. It is the smallest of the three images. See the Pup page.

Snout — GNOME

For those who prefer GNOME as it is: no dock, no global menu, no third-party themes. Snout ships Fedora's official GNOME Workstation environment, and CapivaraOS's identity shows up in the wallpapers, the boot splash, the login screen and the "About" panel. See the Snout page.

A new visual identity

All three images debut the new CapivaraOS logo — a walking capybara, original artwork made for the project. It replaces the previous logo everywhere: wallpapers, icons, boot splash, login screen and installer. We also rebuilt the photographic wallpapers, using capybara photos from Wikimedia Commons under free licenses, with the photographer's credit embedded in the image.

ISOs now ship up to date

One fix worth calling out: the images now ship with Fedora's updates already applied. That was not the case in the first Marsh ISOs — the updates repository was being skipped while the image was composed, so anyone installing found around a thousand update packages waiting on first boot. That is fixed, and the build now runs an automatic check that stops the process if the image comes out outdated.

Downloading safely

Every image is on the Download page, each with its own link and SHA-256 checksum. We recommend verifying the checksum after downloading — it is quick, and it proves the file did not arrive corrupted or tampered with. The instructions are on that page, and a .sha256 file ships alongside every ISO.

For your own safety, download only from this site and our official SourceForge project. Be wary of any CapivaraOS-named ISO coming from another source.

What's next

The focus now is stabilization: listening to people who installed it, fixing whatever turns up and maturing the three editions. If you give one a try, tell us how it went — what worked as much as what broke. Open an issue on GitHub or reach out through our contact form.
