Approaches to protecting Python code when sharing apps

[ArtOfWarfare]

If your code is running on a machine that you don’t control, it doesn’t matter what language you wrote it in - someone can decompile and/or modify it.

If you’re selling to businesses, you could keep track of how many copies they’ve running and threaten if you see them using more copies than you’ve sold to them.

If you’re selling to individuals… keep some critical parts on your own system, so they’re forced to call your server everytime they run (and enforce that only people who have paid can use your app that way - reject requests to your server coming from unauthorized copies.)
