Glad someone noticed :) Almost felt too silly but then I just decided to add it anyway.
I would not really consider it off the ground yet, I launched on ProductHunt (#5 product of the day) which gave some initial users, and from then on mostly been cold emailing people. (Every site has some issues, so I can just point people to a free first report and its already useful)
Actually I find marketing/getting traction harder than building it in the first place.
