Catapult is an app launcher for Linux.
It allows you to easily launch apps, open files and do basic calculations with a keyboard-driven user interface.
This is free and open source software.
Key Features
- Custom plugins and themes can be loaded dynamically.
- Remember choices also for prefixes of search query, e.g. if searching for “music”, also save choice for “musi”, “mus”, “mu” and “m” (this should help avoid results jumping back and forth in certain cases).
- Uses GTK4.
- Very small codebase.
- Plugin support.
