Ask HN: What do you use to manage all your domains and hosting?

Doing a little market research here: Those of you who have a lot of projects, domains, and hosting accounts out there -- how do you keep it all managed?

I am familiar with a mac app called Domain Brain [1], but I was wondering if there were a SaaS app out there that can alleviate this pain of managing this.
