Electron apps not integrating or otherwise doing whatever they want to do is a huge reason why I don’t like them and I wouldn’t consider it to just be a blanket statement.
I don’t remember the name of every one I’ve dropped, but maybe you can find them based on the description. First one I can think of was a torrent client. The reason I dropped it was because it enforced the macos decorations on all platforms. Meaning it was the only app on my system with all of the window buttons (close, maximize, minimize) on the left side of the app instead of the right. On top of having different colors, I’m not used to.
There are many apps that seem to have bugs due to their electron version or just electron itself, which all of them seem to be having different versions. Most famous is discord, but even apps like signal desktop. I’m currently dealing with a bug that requires me to launch the app twice. It happens in the flatpak and the repo package. Unfortunately they aren’t fans of third party clients, so we are basically stuck with it.
On top of that like many others have mentioned they are resource intensive in both ram, disk space, and cpu. I have literally had to help people on these very forums who are new and don’t know any better. There was a person who pretty much seemed to unknowingly use only electron apps which would eventually cause that person to run out of memory.
Furthermore, electron apps often rely on the web implementation of certain features. On top of increasing the attack surface. This can also reduce privacy as we expose more of our desktop computing to what are essentially just websites. There is a reason why on phones everyone wants you to install their apps. While it isn’t as bad on desktop many electron apps are just websites. Using the same trackers, reaching out to google / facebook services and without the option of using a hardened profile or ad blockers while in this state.
Now yes, traditional desktop apps can do the same, but isn’t as prevalent as it is on the web is the point I want to make.
Now I know you wanted more concrete examples, but we are talking about apps I have dropped and then never thought about again here, so unfortunately I am drawing a few blanks.
But in an effort to try and come up with as many concrete examples as possible. I am digging through my web history, installed apps list, and pacman log to try and find things remember why I dropped them or why I don’t like them.
So far I have found apps like hakuneko which is a manga downloader. It refuses to open unless you disable the chromium sandbox. Unfortunately, not a lot of alternatives, so I keep it around. Now that I think about it this isn’t the first electron app I have had that problem with, so the quality of these apps are all over the place.
Anyways to sum things up, no one technology exists to solve every problem. The explosion of the web lead to companies needing a lot more web developers than anything else and now there are large swaths or developers who only seem to be able to use web technologies.
Edit: Might I mention how slow a lot of them are. I have a bank account with two different financial institutions here in the state. They have converted all of their apps to web apps and thus electron. They take multiple seconds when going between certain pages. This is for both apps from both banks.
Now they aren’t all bad.
VS code is hands down the golden standard for electron apps, but it is by and far the exception and not the rule.
