There is too much info on the main page. I have looked at the page briefly twice (while writing this) and I still don't know what the app does. That scrolling image in the middle should tell me what it does, and not show me an abstract example of a screenshot of the app.
Upon looking at the page a third time, I see the following: web + database apps made easy create portable, open-source PHP/MySQL/Ajax web apps in minutes.
That doesn't sound specific enough. What problem is this solving and why should I care?
Looks like you put all of your links in the navbar in the header. Maybe you can reduce the number of links there and move some of the others either throughout the page or to the footer (e.g. the blog, contact us, etc.)
The 'free 14-day trial' button doesn't jump off of the page enough. It's your only call to action but it doesn't grab me, per se.
Other than that, congrats on actually launching.
I am not being mean, just trying to give constructive feedback.
Good luck!
[edit] All of the above was for the marketing site...not the service itself.
