Wave version 2 has been released and it's available as an open-source project. I feel that a good direction to go in might be to offer this new version as open source. After it gains some good traction it might be a good strategy to build some new tools and plugins for the project in order to monetize it. This way I can continue maintaining the project and adding new features.
Although the software is free to use; only users with a DevDojo Pro (https://devdojo.com/pro) account can access all the video tutorials and the discussion/issues private repo.
At least this way the script can be available to as many developers as possible to help them create their own profitable SAAS application.
Either way, I'll be excited to create some SAAS products using this script as well. Happy coding!
