Run tool window

The Run tool window displays output generated by your application. If you are running multiple applications, each one is displayed in a tab named after the run/debug configuration applied.

If you re-run an application, the new output overwrites the contents of the tab. To preserve the output of an application, even if you re-run it, pin the output tab.

Learn more from Debug a Vue.js application, Debug an Angular application, and Debug a React application.

The appearance of each tab depends on the type of the application being run and can include additional toolboxes and panes.

The main toolbar of the Run tool window lets you rerun, stop, pause, or terminate an application. The following table contains descriptions of the buttons that are common for most applications.
