I've built PWAs for quite some time ( a little over 10 years ).
I believe memory usage depends on the libraries the developer has included and how they decide to store the data.

The App below currently has all ( minus deactivated ) data included in the following:

It was installed using Chrome and includes an instantaneous 'super search' for all data.

This currently running PWA only takes up about 26MB, according to Activity Monitor.

Is this too much memory usage?

PS. I have not installed the beta, nor tested it with Safari.

Interesting. Was that running with Chromium? I notice when building them for a site, not from scratch or of my own, but let's say of MacRumors or any site that they spawn a ton of Electron processes.
Was your PWA not a Chromium based one?

Running with Chromium? That's a great question. I always assumed it ran with a "chromeless" version of the install browser. Maybe it does run via Chromium ( I don't know ) when installed via Brave, Chrome or Edge on desktop.
The app process appears to be independent of the browser ( standalone ). But does NOT appear to run if the installing browser is deleted. I remember a long time ago, deleting the installing browser would remove the PWA, but now it appears to pop up a selector to start another browser.

No, the PWA app I developed is not chromium based.
Maybe MacRumors used Electron to create the desktop application. Electron is quite heavy.
 
Hi folks – I created a Gmail dock app. Seemed to work fine. Didn't need to log in... Until the second time I opened it. And I was right back to the Gmail login.

Yet if I opened Gmail in Safari I was still logged in. I had really hoped that the Dock apps would literally just be app-ification of browser tabs, so they would share the same cache, same plugins, same logins etc as Safari at any given moment. But it seems they're separate instances of Safari.

Is this right?
 
They only seem to work with Sonoma as I am not able to add a Web app in Ventura with Safari 17. Unfortunately my 2017 13 inch map does not support Sonoma. What a shame they are feature locking safari with the web apps and iCloud Keychain use in third party web browsers. Two features I was hoping my old mb would get. :(
 
This was the biggest eyeroll moment of the WWDC keynote for me. (I liked all the rest)

PWA's are a thing for years and years. They even got a spokesperson and demo for pinning a webapp and made it sound like they invented something magical and revolutionary that will enrich people's lives.

Can't believe it took them so long to add something that has been considered 'a basic feature' for years on other platforms and browsers.
I only have one complaint about this, and I'm not sure whether it's common to all the webapps or just the BBC app I'm running. No "Back" button appears in the app - I soon found a "Back" (and forward and reload) option in the mouse right-click menu, but it's not intuitive when switching between webapp and browser. Any fixes? Also after switching from the webapp to this forum my pointer disappeared!

Navigation would have to be built into the application. This would appear to be a BBC UI/UX issue.
 
Is it possible to make the dock web apps open in other browsers rather than Safari? I prefer to use Firefox.
I don't think Sonoma web apps are opening in Safari at all; they're standalone apps that run in a macOS-native window using WebKit as the rendering engine.

TonyG1 – "Settings > General > Show navigation controls" is available in the main menu for each web app. (Is that what you were asking?)
