Take Backpack offline with PackRat

Got a Mac? Use Backpack? Wish you could access your Backpack data while you were offline? Your wish has come true. PackRat is here.

PackRat is a desktop client for 37signals' Backpack web application. PackRat lets you use your Backpack data when you can't be online. Before you hit the road for the first time with PackRat, just sync up with Backpack and your data is duplicated in PackRat's database. View it to your heart's content. Edit it to your heart's content. View it in ways only a desktop application can. When you get back online, PackRat will automatically inform Backpack of all your changes and Backpack will be up to date. From then on you can just use PackRat and your Backpack site is automatically kept up to date.

David Chartier from The Unofficial Apple Weblog said "[PackRat is] the killer syncing and offline Backpack client that does even more than Backpack itself". Check out PackRat for yourself.
