How can I better protect my web application from copying and changing when selling?

Question

Information Security

Hello!
How can I better protect the web application from being copied and modified if we sell the application with the server together? Back and front are in separate directories. The back is written in Flask and the front is written in VueJS.
Thanks in advance!

If you support the product after the sale, that's your pain. If not, it's the client's pain.
How do you protect an application that you completely give away? - no way.
You sold it, it's not yours anymore. Why even think about it then?
But if you sell, BUT, without you it will not be able to work - this is already a field for thought.
Anything you put together, someone else can take apart. Anyway. Especially if he has everything in his hands.
But if you sold, but without "this one here ebanina" will not work (which only you have) - you can temporarily defend yourself.
I've always liked this kind of carbon monoxide approach on the web. You buy something, but without js it won't work on their server. Who will prevent me from pumping it out?!)) Who will prevent me from changing something if everything is on hand.
If you sold - forget it. Otherwise - you gave for rent
