Lightweight browser to run AltUI in raspberry kiosk mode?

Hi everyone, first post here. This is not a real problem, it is more an ask for advise.

Does any one run successfully AltUI in a browser other than Chromium on Raspberry?

I have a “home panel” ( = old monitor + raspberry) in my kitchen to display news, calendar and some custom Altui pages. A script flip the tabs in browser periodically.

I’m using Chromium browser on raspberry. Everything runs ok except by cpu consumption, it stays mostly at 100% (mostly from Chromium processes).
As I want to put some more stuff to run on this raspberry (basically voice prompts), I’m playing with other browsers to see if I can somehow reduce cpu usage.

The best results I achieved were using kweb . After enabling Javascript support on it, it rendered nice all my pages (except AltUI ones) with less than 50% of total cpu load on peak.

But unfortunately Altui pages refuses to load (it just show the ‘Waiting Initial Data’ and nothing happens). I waited up to 10 minutes.

Any advice?

Sounds like a JavaScript issue with the browser. Can you get a console log out of it, to see what it’s waiting for?

Not sure this forum area is really the right place for this fairly specific, and AltUI-related, question? Better perhaps in Plugins (AltUI) or maybe Apps & Remote Access?

@amg0 is the expert on this, but not sure he follows this section of the forum.

Altui supports chrome and edge chromium it uses various libraries doing fairly sophisticated things…so this is probably not supported.
