What is KRunner?

KRunner was introduced with KDE 4 as a quick‑launch tool, evolving into a powerful command line interface that can be invoked with Alt+F2 or the custom shortcut. Over the years it has grown to support plugins for web searches, unit conversions, and even scripting, making it a mature component of the KDE ecosystem.

It is aimed at KDE users who want a single keystroke to access almost anything: launch programs, open documents, or run shell commands. Its minimal UI keeps the focus on speed rather than visual flair.

Compared to Windows PowerToys Run, KRunner feels more integrated with the desktop. It offers deeper command‑line access and a plugin architecture that lets you extend it with custom scripts, while PowerToys Run is more limited to launching and searching within the Windows environment.

Best for: Power users on KDE who need a fast, keyboard‑driven launcher with extensibility.

Tips for Windows users

If you’re moving from PowerToys Run, set the KRunner shortcut to Alt+F2 or a custom key. Use the same command syntax for launching apps (just type the program name). For file opening, type the file path or use the file picker plugin. Calculations work the same way; just type the expression. Remember that KRunner can also run shell commands, so you can replace PowerToys Run’s custom scripts with simple terminal commands.
