Developer Certificate for Xcode

I'm developing an open source GPL macOS app for the amateur radio community and I want to know how to 'archive' it so people can download a compiled 'bundle' from my GitHub page for free. I have an Apple Developer account, but I haven't enrolled or paid any money. Is this possible?

Maybe you could try Archives - Distrubute App - Development. It seems working if I use a free Apple Developer Account to sign it and send it to my another machine.

Maybe there is some limitation for this method. (Say user have to go to Setting and choose allow any source)
