Gabtastik is a WebKit based Site Specific Browser (SSB) for web chat services currently in Beta that runs on Windows XP, Windows Vista and Mac OS X 10.4 or later computers. The Adobe Flash Player is the only other requirement besides an account at Facebook and / or Google Mail.

The beta version does not offered a lot of add-ons over the original chat applications on the websites. We already covered performance and the only two additional features are transparency which can be set in the desktop client and the ability to quickly switch between both chats. But that is more or less also provided in modern browsers where users can simply switch between tabs to do the same.

Interestingly enough the Mac client of Gabtastic in version 0.20 is supporting meebo as well providing access to several Instant Messengers like AIM, MSN and Yahoo while the Windows 0.21 version does not support these yet. The creators definitely have to add more value to the application to make it a must have alternative.
