The website looks really interesting and very useful if it works like in the demo.

My only issue is $79 / mo starting plan looks a bit steep for casual development (I know there is a free option) but if you want to attract more buyers i think something like GitHub's pricing would be really attractive for prospective buyers like me (something like $22 / month for 10 private projects with 10 pages / min). Just a suggestion in case you're looking for feedback.
