That was basically the same claim LP made. Even if true, if you have a bad master password, you can be compromised. While yes, that’s on you, your data is a high priority target in a centralized password store… if you host it yourself, someone would first have to know you had that data to even target you for that. Much less exposure hosting it yourself. The convenience factor and potentially less security than a company hosting passwords have, so it’s kind of a six of one, half dozen of the other.

Raspberry Pi will handle it.

It’s all about the storage space. Processing requirements are minimal.

I switched from Lastpass to 1Pass and it was pretty miserable. I then swtiched to Bitwarden. It’s not perfect, but it’s better than LP and 1Pass.

The reason you’d want to self-host is so that nobody has access to your data but you. “The cloud” is just someone elses computer"

Nobody can answer this because it depends entirely on how you set it up. It can be set up either way. Whatever you point your internal endpoint at is what it is.
