Bitwarden has been nice. I migrated from 1password and while I can easily recommend both, I think I like Bitwarden more, especially on Android where the fill service works more consistently.
What do you even need the app for? You can just use the browser extensions. I also just tried the desktop app and it's not too bad for an electron app, not particularly good either tho.
Is using electron/chromium an actual problem? Assuming it works, would you say the same thing if it was made in winforms on .net framework 3.5, or something as old as Qt 3?
It's one of the better electron apps I've used. I also like to avoid them (actually you can just run the website in a browser), but "open source" definitely is far in front of "doesn't use electron/any web tech" in my list of priorities.
