I'm actually quite liking the looks of your service, and I'll probably start using it soon. I have only a few suggestions for additional features:

1. Check for open ports, to allow for non-websites (is my ssh server running) 2. icmp ping. (My ssh server is inaccessible. Is my networking/router down, or is it just my computer/program crash) 3. RSS feed for each defined check. This would allow integration with other services like IFTT. 4. Push notifications. First party or via other services; I personally send Pushbullet notifications for stuff via [1] (and currently looking at [2]), previously with npm and bash scripts; Pushover is fairly similar, and I've seen a newish offering called Pushkeep. Generalized webhooks might also work (I believe Pushbullet can be used this way, not sure about others).
