Hi! I have a Patreon which I use mostly as a blog (with most posts being public). The only real "reward" for my patrons there is that occasionally I build and make available native versions of my generators including 1PDG. So if you want you can become a patron to access those native (win, macos) applications.
Alternatively, you can try to download all the files of the generator from itch.io to run it locally. It is definitely possible, but I can't provide any instructions - that's not my area of expertise.
Cheers!
