A tiling window manager won't save you when dealing with Electron apps.
I run Linux and StumpWM on my desktop, and recently I had upgrade to 12GB of RAM, because it turns out 8GB is very easy to exhaust these days. I currently have 9.3GB tied up, mostly by browser processes.
Yeah, this. I'm mostly using swaywm instead of Gnome in order to free up about 1 extra gigabyte of RAM for apps, but that equals about one Electron app. The only Electron app I haven't eliminated from my daily usage, though is Patchwork, so it's not so bad.
