I want to have both linux and mac users (but maybe also android, ios, windows).
You clearly see the issue.

I don’t. VLC is available everywhere, so your requirement is clearly not a problem. Jetbrains is available on all major desktop OS.
When I started programming, one had to repeat in Assembly the same application for each computer brand.
We are not that bad nowadays, it is a skill issue.
There are plenty of ways to have portable applications with native UIs without shipping a browser.
Somehow we managed to do it for decades and without AI writing the code for us.
If you want to ship a browser, I already have one, thus standard Web, with a daemon if it really must be.
