TweetDeck, the popular Adobe AIR-based Twitter client, started offering a web-based version of its service in Google’s Chrome Web Store late last year. There, it quickly became one of the most popular apps in the store. Today, TweetDeck is launching a limited beta of the web-based version of TweetDeck that will also be available to users of other browsers. Specifically, TweetDeck Web will work with Chrome, Firefox 3.6 and 4, as well as Safari. Support for IE9 and Opera is coming soon.
TweetDeck is obviously not the first Twitter client to go this route. Seesmic, for example, has been offering a web-based version of its client for a long time already. Just like Seesmic, TweetDeck’s web version will look very similar to the original desktop-based product. One major difference, however, is that it will no support Twitter streaming.
For now, this is a private beta only. Only whitelisted TweetDeck accounts will be able to access to the beta at this point. You can sign up to be whitelisted here.
