What application launchers are available for Ubuntu?

What are some alternative launchers that can be used to launch programs in Ubuntu's default Unity desktop?


One that I use and like is Albert.

It's very similar to OS X's Spotlight Search, especially in how it looks, but I've found it to be invaluable if you're a keyboard-heavy power user.

You have to install it via a PPA (not in the official repos yet):

sudo apt-add-repository ppa:flexiondotorg/albert
sudo apt-get update
sudo apt-get install albert

On the first launch you will have to set the hotkey to launch Albert, but that's fairly easy:

I've set it to Ctrl-Space.


Docky is a great app, you can install it with:

sudo apt-get install docky

GNOME Pie is another great one that can be installed with:

sudo apt-get install gnome-pie

(Launch with CTRL + ALT + A - this hot key is customizable.)


Cairo-Dock is also good, and can be installed with:

sudo apt-get install cairo-dock

Plank is another good one that can be installed with:

sudo apt-get install plank
