I've already published a few apps for the Mac App Store and am just wondering if there are alternatives to the Mac App Store? I would prefer not to self-host the applications (because I know almost nothing about servers) and would like a system like the Mac App Store where I just upload and forget about the distribution infrastructure.
Any easy and creative distribution methods would greatly be appreciated.
Setapp is a great alternative. It's a subscription service for Mac apps. Users pay per month and they get a great list of apps.
Besides that, they help you with marketing so you can focus more on development. You can apply your app in https://setapp.com/developers.
