for people using Sonoma already, do you need to have safari itself opened , in order to launch a web app/pwa ? or can it be open undependantly?
When you add a website to the Dock/Launchpad, it creates a "web wrapper" app independent of Safari (but still using WebKit). It's like a mini browser.
Note, this is NOT the same as a PWA, which requires that the website be built using specific PWA technologies. However PWA apps *combined* with this new web-wrapper feature brings us the closest to a real native app that you can have.
