Fluid is an application that allows you to create your own .app (application in your applications folder) from any website. It works great on sites such as GoogleReader or GoogleMail, as well as MobileMe and many other.
Fluid itself is a very small application. When launched, Fluid displays a little tiny window where you specify the URL of a WebApp you’d like to run in a Site Specific Browser. Provide an application name, specify a Location and an Icon (see flickr for lots of icons), click ‘Create’ and you’ll be prompted to launch the new native Mac app you’ve just created.
Fluid also offers the ability to convert your favorite webapp into a MenuExtra SSB – an SSB that exists only as an icon in your OS X system Status Bar next to other MenuExtras like the Clock and Spotlight. Click the MenuExtra SSB’s icon and your chosen webapp appears as a drop down window. Perfect for sites you access multiple times a day (Twitter clientsÂ Hahlo, email, or Digg) – see image below. Works especially great with iPhone webapps on your desktop.
Apple is promising this kind of webapp implementation in the new 10.6 OSX but we hope that this does not affect Fluid development. The application is fantastic and new features are added all the time.
If you rely or use webapps often, Fluid is a must!
