There has been a big move to web based apps (SAAS) as web-based software has improved. The biggest plus to web based software for the user is that there is no need to install anything.

BUT, you are going to be paying a monthly sub as long as you keep using the service. And soon as the service goes down (due to financial or other reasons) - game over man.

So there is still a lot to be said for downloadable software, even if it is no longer cool or fashionable. Pay once. Keep your data secure locally. Keep using it until you can't find a computer that runs it any more.

I develop 3 commercial downloadable software products. No plans to move them to web.

Yes! And I think this way of building software is having a come-back with the local-first movement! https://lofi.so/
