I gone through a lot of hosting service providers and unfortunetly cannot find a single one that can be used without running nonfree programs, all of them require loading bulky obfuscated JavaScript apps.
I know of Codeberg Pages for static sites for example, but it is not suitable for any business or professional use.
Something like that would be seen as huge deal when talking about mobile or desktop programs
That’s because mobile and desktop programs have far more access to your system compared to Javascript programs that run in a permissioned sandbox. They are not the same thing.
that in my opinion should already be build by the server
Eh, that’s debateable honestly. Sometimes pages built by dynamic Javascript have much a much better and fluid UI experience than server-side rendering, which require slow full-page reloads. To each their own though, there’s benefits and disadvantages to both methods.
