CheckItOut, Personal Finance Manager CheckItOut is a new Web 2.0 application written for Ruby on Rails, which lets you manage your personal finances in a web browser. It's an open source project that you can install on your own server or have it hosted on a Ruby-friendly service. The online demo indicates it's a bit too bare-bones for my needs (for example, it doesn't appear to have any data-import tools at this point), but it's certainly an interesting project.
