About

Launcher Studio is a modern, native GTK4 application designed to simplify the creation and management of .desktop files on Linux. Whether you need to fix a broken icon or create a shortcut for a standalone AppImage, Launcher Studio provides a powerful yet simple interface.

Key features:

  • Basic editor for name, executable path, and icon selection.
  • Advanced settings: Categories, Keywords, MimeTypes, and Startup notifications.
  • Raw Source View: Inspect and edit the .desktop file content directly.
  • Native integration with GNOME and Libadwaita (Dark/Light mode support).
