Hello Felix!
With the free version of Superbase NG you are not allowed to redistribute any software you make (since it is for non-commercial use) so creating an executable file for the project is not possible.
If you have paid for the full version of Superbase we happy to help you wrap your project into an executable file and even build an installer, for a fee, and the best way to do that would be to get in contact with us via email in**@**perbase.com
