Fluid

Fluid gives your favorite Web apps a home on your Mac OS X Desktop.

Are you a Gmail, Facebook, Campfire or an insert-your-favorite-webapp-here fanatic? Do you have 20 or more browser tabs open at all times? Are you tired of some random site crashing your browser and causing you to lose your (say) Google Docs data in another tab? If so, site-specific browsers (SSBs) provide a great solution for your webapp woes. Using Fluid, you can create SSBs to run each of your favorite Web apps as a separate desktop application. Fluid gives any webapp a home on your OS X desktop including Dock icon, menu bar, and logical separation from your other Web browsing activity.

How does it work? Fluid itself is a very small application. When launched, Fluid displays a small window where you specify the URL of a webapp you'd like to run in a site-specific browser. Then provide a name, click 'Create' and you'll be prompted to launch the new native Mac app you've just created. Use it to run YouTube, GTalk, Flickr, Basecamp, Delicious, .Mac webmail, or any other webapp as a separate desktop application. Anytime you click a link to another site in an SSB, the link is opened in your system default Web browser, keeping your SSB dedicated to the original site you've specified.
