Keepassxc and Syncthing to sync between devices.

i've been using bitwarden for a few years and haven't had a problem, but always looking for something better for everything

Another for KeePass + Syncthing.

No self-hosting required. Just install both on whatever devices you need to access passwords, and let Syncthing handle the rest. KeePass is designed to handle multiple simultaneous connections to the database and can sync on the fly.

I'm curious, what's your use-case since you say you can't self-host.

Where do you need to sync to? What kind of devices do you need sync between? Do you need to share some credentials between people?

Knowing these things will help us answer the question. For example, you don't need some "server" to host Vault Warden - that can run on your own PC/laptop. But there are other ways to do this like Keepass (already mentioned).

What are your thoughts on Keeper?
