Change Katalon Studio theme

  • You might find the Dark theme in version 9.0.0 difficult to read as the black text is displayed on gray background. Go to System Settings > Appearance, and change the theme to Dark. The theme should work normally as previous versions.

Enable Dark theme

By default, Katalon Studio is in Light theme. To enable the Dark theme, go to Window > Themes > Dark.

Restart Katalon Studio to apply the new theme.

To switch back to the Light theme, select the Light option.
