I feel the issue is if you're successful with this idea and get on radar of Microsoft, they will make sure to snatch away all deals from you by bidding even lower. They have money to lose. Small firms generally don't.

I know it might not look very modern but K9 mail is the most clutter free no bs email client I've ever used.

So it can also do tooling like vite but it primarily aims to replace node as a better and faster js runtime since they're rewritten most js api in zig and c++ from what it shows on their github. I'll give it a try sometime and see if it's really all that fast and easy as it claims.

Javascript isn't my primary language but How is it different/better than vite? I've used vite for a few vue projects and it felt really fast.

I'm not sure I've seen a backend written in Kotlin despite how prominent it is for app development.

I worked with really Big Bank who have their whole backend written in kotlin. It was such a great thing to witness because usually financial institutions don't give a fuck about clean code and modern programming languages.
