I like the concept and have longed for this for some time, but I'm not a fan of the big sign up button without an easy way to know the price (maybe t's through that button? I dunno and don't want to put the effort in if the price isn't reasonable). My suggestion: make a pricing link or put pricing into on the front page.

(I'm on a mobile device, so these comments may not apply to a full size browser.)

Thanks for the feedback! We'll definitely look at the right way to surface more info before signing up. (For the record, it's $5/month.)

I'd been planning to do something like this as a little side project. Never considered the fact that it could be monetized. Oh well, you live and learn. At least I don't have to feel guilty about never starting it now.

Congrats on shipping!

Thanks!

Seems like https://gemnasium.com but for node and python. Looks nice though.
