Pro Edition - Paid. Full functionality as reflected in documentation. No limits for project complexity.
CloudaIDE Pro licenses are per named developer, and not per PC, Server, Database or Location. Therefore you need just one license for one named developer, even if you are running multiple instances on multiple machines. They are not limited in time (ethernal). The deployment of compiled application is free.
Under the support contract a named developer will be entitled to receive incident based technical support by e-mail.
