Each electron app has its own Chromium runtime. With the prevalence of electron apps, the result is multiple instances of chromium running on your machine. Chromium isn’t light weight. On top of that, there is the philosophical aspect. Do we really need to be shipping an entire browser for the purpose of creating a UI? That being said I understand why so many electron apps are created. HTML/JS/CSS are powerful and easy to use (IMO) and cross platform. I just try to avoid them and use alternatives to electron.
