Our Agency plan customers have a possibility to show their panel to their clients or teammates without downloading or installing the code.
There is a button called Send to client which creates a special temporary URL for that specific project.
And then you can create specific users (email+password) to log in to that panel.
After they login, they will see the same panel you generated online, just stripping out any menu items or buttons for generating code. So clients or teammates will actually see only the final result and will be able to play around, enter some dummy data and see overall progress.
