Web applications like Gmail, Facebook, Campfire and Pandora are becoming more and more like desktop applications every day. Running each of these web apps in a separate tab in your browser can be a real pain.

Fluid lets you create a Real Mac App (or "Fluid App") out of any website or web application, effectively turning your favorite web apps into OS X desktop apps.

Creating a Fluid App out of your favorite website is simple. Enter the website's URL, provide a name, and optionally choose an icon. Click "Create", and within seconds your chosen website has a permanent home on your Mac as a real Mac application that appears in your Dock.

Fluid is free. You can download Fluid for free and create as many Fluid Apps as you like.

However, for $5, you can purchase a Fluid License which unlocks a few extra features:

1. Pin Fluid Apps to the Mac OS X Status Bar. (Fluid App Menu → Pin to Status Bar…)
2. Use Userscripts or Userstyles in your Fluid Apps. (Window → Userscripts)
3. Use Full Screen mode in your Fluid Apps. (View → Enter Full Screen)
