The github link is a really hidden small icon. I probably also don't care about the source, but if it is hidden, it looks like it is difficult to get and/or install.

Your front page says of the paid version: "Don't worry about installations, hosting and upgrades. All plans include a 30-day free trial. No credit card required."

My first impression was that it is hard to upgrade. Maybe not true, but it is what is communicated by the site.
