I believe Keypass uses local password vaults. I don't use it personally, but I have heard many people use a combination of KeePass and Syncthing to sync their passwords across multiple devices.

I wouldn't recommend Keypass to my non-technical family and friends, but if you love the command line it might be what you are looking for

Bitwarden offers both a hosted and self-hosting option. Though their code is open source unlike LastPass and 1Password.

It works great but you'll need a reverse proxy with TLS + a domain if you want to use the android app.

Self signed certs don't play nicely with the app.

Setting up a reverse proxy + TLS is not that hard. Buying a domain + paying the 10€ per year license (If you go with the official server rather than vaultwarden) is still cheaper than paying for Lastpass / 1Password / Dashlane for the same time. As long as you are willing to maintain it that's pretty reasonable.

The only thing that makes me mad in bitwarden's official client is that you STILL can't remap your keys. I still have the old habbit of Ctrl+L from Keeweb to go to the search bar. On Bitwarden it locks your vault...

Consider using ZeroTier or any WireGuard based SDN instead, for remote access to self hosted services.

Keepass2 is a piece of cake. Apps on desktop and mobile, keys stored in dropbox or whatever.
