I've been able to find http://www.macbartender.com/ that allows to organize and clean up Mac OS X menu bar.
Are there any alternatives to this application?
This is a very vague question, but some programs with similar features to Bartender are:
Broomstick is the easiest way to hide menubar icons that you don’t like. While most apps that create a menubar icon allow you to hide it, some apps don’t provide this option. Broomstick lets you take back control of your menubar!
AccessMenuBarApps is a simple app that gives the user instant access to all menubar apps by showing a reduced app menu (so that there is more space for menubar apps). Activating/Deactivating of the reduced app menu can be triggered by keyboard shortcut, mouse gesture, click on the menubar icon or click on the dock icon.
