Thanks for the feedback.

I blurred the screenshots as they didn't look nice. I just have an ugly prototype so far. I wanted to ask for more feedback and validate the market more before spending more time on making the system nicer.

Currently you cannot sign up. You can only enter your email in a list and get notified when the product launches.

Cool. Still, I wouldn't blur them. I think this is a difficult market to be in. Think back to all the hosted CMS's in the past. If there is really demand, there will be a free solution that you run yourself.

A free self-hosted solution is definitely competition. But many people will probably still think it is convenient to use a hosted service and pay for it.

It's the same with Gmail, salesforce, 37signals products and many other services. There are almost always free open-source alternatives, but not everybody wants to deal with installation, hosting and maintenance of those solutions.
