We just launched on HackerNews. (https://news.ycombinator.com/item?id=25740780)
Not much of a response so far (only 7 upvotes) but we've gotten some traffic which is great.
I think there are a few possible reasons for the lack of a great response:
Poor timing? (though I saw a post that said Monday 4PM-5PM PT was generally good - which is around when we posted)
The title was too specific (focused on the AWS market when our tool will eventually be generic)
No PMF :(
