You're actually right, by now browsers have APIs to do most of the things apps do. Technically you could convert most apps to websites. I guess as a user I just don't want all my apps to open a tab in my browser. I want to move apps between virtual desktops and monitors independently and I don't want my app's window to be clattered by all the menus from my browser. On mobile I also prefer switching between apps than between different tabs. For me the best compromise is:
- for system tools that don't have to be cross platform and critical apps write native apps
- for small/medium cross platform apps use webviews like Webview2 or Tauri
- for big apps like Teams or Discord just use a website
Do you know any websites that integrate into Linux desktop and Android like native apps? I mean I can run it from cmd/icon, and it opens as new window without any decorations? I never saw it but if it's works fine it's an interesting option.
