CheckSite is a handy tool for web designers/developers.

I got tired of keeping a terminal window open to monitor my clients' websites. CheckSite gives me an integrated and unobtrusive way to do this through the OSX Notification Center. The app runs in 64-bit mode too, which is a prerequisite for me.

The developer is responsive and open to feedback, and I think the app is reasonably priced.
