On the free plan you can manage sites you have hosted elsewhere or launch a demo site, while on the pro & business plans you can deploy "regular" sites (and indeed blueprints) to our cloud.

You can see the difference on the add site page between the 2 plans:

So once you have subscribed to the Pro Plan, the Launch New Site button becomes active. After clicking on this button you will be presented with a form to provide the initial details required to deploy the site, and confirm it's deployment.

|| Note that sites hosted on our Private Cloud are priced at $10/month pro-rated to a day. So if you only deploy a site for a day, you are only billed for that one day, and not the entire month.
