There are many graphical environments available for Linux. The most popular are GNOME and Plasma, which use GTK and Qt respectively. frameworksAlthough what's designed for Linux usually works on other systems, not everything performs equally well in every installation. For that reason I created an interface for YT-DLP using Vibe Coding.Because Parabolic It's very good, but it annoys me to use GTK applications on my desktop. For virtual machines I use GNOME Boxes, but I'll probably switch to Board when they release their first stable version.
What is Karton? It's an application under development that It was presented at GSoC 2025 y aims to be an alternative to GNOME BoxesBut it's for KDE users. Its name is quite amusing: as is almost always the case with KDE, it has the letter K, and the full name would be the material from which boxes are usually built (for GNOME Boxes).
Karton is still under development
The reason for creating Karton is integration. Most users opt for GNOME Boxes when they want something simple to run virtual machines. The intention is Create a native application for Qt-Quick/Kirigami with libvirt in the background.
Now, although there are a couple of videos published like the one above, right now there's little to nothing you can do. At least not on my computer. What's available allows you to see the existing boxes (like the GNOME Boxes) and create them, if you're using an ISO of something already released (it doesn't work with Ubuntu 26.04 beta, for example). But opening them, in my tests, doesn't work.
Among the future plans:
- Include support for snapshots, so we can revert to a previous state.
- Add system monitor to view CPU and RAM usage.
- Redesign the user interface.
- Installer improvements.
I'm keen to switch from GNOME Boxes to Karton, but it'll have to be worth it. We'll have to wait and see how development progresses.
