If you are looking for another one: I use https://sqlitestudio.pl which is GPL-3 only and also cross platform. I'm not sure I ever compared them, I think I just came across sqlitestudio first and it stuck.
It's been a few years since I've used DB Browser, so I forget exactly what I didn't like about it. Maybe I should download it again and try it out one more time and see if I still feel the same way.
> Portable - No need to install or uninstall. Just download, decompress and run.
and I download the dmg and it's an unverified installer inside. Pass.
I run on MacOS, I have no idea how I installed it, but I haven't had any trouble.
