I did ask the same question in 2016 [1] and got some really interesting answers.
I'm still chasing the dream of having a side-business and earning some side money, but with web apps it means mostly SaaS. Personally I hate rent-seeking behaviors (I'm not alone, it seems - "Tell HN: A Conversation Needs to Be Had over Subscription Software" [2]), so I'm trying to know what people are doing regarding desktop apps.
Are people still building desktop apps? More specifically, can you make a living (or earn some side money) in 2022 by selling a desktop app?
Please share it with us, or are we doomed to build web apps and SaaS for the foreseeable future?

Although .Net went multiplatform years ago, my app relies on WinForms a lot so it's Win only, except through Wine. I would love to support Mac as well but the only realistic option looks to be Electron based, and it would be a significant step back for my Windows users. Maintaining two different GUIs looks like a problem for micro company.
The best thing about desktop software is it can't break for all the users at once like server-based app can. That gives some piece of mind when you're micropreneur. Sure, there are bugs, but they affect only users who downloaded buggy version. You can't crash all installed instances just like that.
The worst thing is, it's hard to ask for a subscription. Yes, I hate it as a user, but would love it as a business owner :)
