KAppMan – KDE AppImage Manager

A lightweight, KDE-native AppImage manager built with Python + PyQt6.

Features

• Auto-integrate AppImages from any directory you choose
• Desktop entries auto-generated in ~/.local/share/applications/ (XDG compliant)
• Folder watcher — drop an AppImage and it's integrated instantly
• Configurable watch directory — set it from the GUI or CLI
• Live theme switching — pick any .qss file from a directory; ships with four themes:
  • Catppuccin Mocha (default)
  • Catppuccin Macchiato
  • Catppuccin Latte
  • Breeze Dark
• Custom themes — drop your own .qss into the themes directory and it appears in the selector instantly

2. Drop it into kappman/themes/ or any custom directory
3. In the GUI, point the Themes Directory field to your folder

Your theme choice and directory are persisted to ~/.config/kappman/config.ini.
