Kontainer is a graphical user interface (GUI) application built with KDE Kirigami that provides a user-friendly way to manage Distrobox containers.
Container Management: Create new containers from various Linux distributions, delete existing containers, upgrade containers and list and view all containers.
Terminal Integration: Open terminal sessions inside containers using the system default terminal emulator and execute commands within containers.
Package Management: Install package files inside containers and automatic detection of appropriate package managers based on container distribution.
Desktop Integration: Generate desktop shortcuts for containers, full integration with the host system through Distrobox and color-coded container listing based on distribution.

Release notes supplied by the developer. These dates are not Flathub package publication times.
1.6.222 Aug 2026
Add Georgian translation, making Kontainer available in a new language.
1.6.14 Aug 2026
Fix Distrobox and container engine detection in Flatpak by using the POSIX shell builtin "command -v" instead of "which", which is not installed on all host systems. This resolves the "Container engine not found" error and the empty "Distrobox path" in the About page.
1.6.030 Jul 2026
Add optional container resource stats display with CPU and memory usage from Podman.
Add binary export and management window for exporting container binaries to the host.
Show Distrobox version and resolved binary path in the About page.
1.5.225 Jul 2026
Fix document portal path resolution for custom home directories and volumes in Flatpak. Folder selections now return real host paths so distrobox create receives the correct directory even without filesystem permissions.
