Growl offers you complete control over which notifications are shown and how they are displayed. You will not receive any notifications that you do not want, because you can easily turn notifications (specific ones or all of them) off.

Ease of use

When you start up a Growl-enabled application, it will “just work.” Your apps can start displaying notifications right away.

Consistency

Growl centralizes all your notification preferences into its preference pane - you can control them all from one place, and you know exactly how they are going to behave.

Powerful

Growl is very flexible. Notifications can be emailed to you or spoken instead of displayed on the screen.
