Firstly, excellent execution of a very useful little tool. I could really use something like this on my site.
That said, I think I could probably build a less polished version in about an afternoon, and having something native provides peace of mind and flexibility.
That's not to detract from your offering, but my hunch is that you'll find a good customer base in larger companies that have a hard time approving development of anything non-business critical. There's immediate appeal in quick integration and allowing the maintenance to be handled by a non-technical person.
