Bitwarden, while not quite as polished, works well. If you have your own server at home you can even self-host, which I do. It's an open source server side app called Vaultwarden [https://github.com/dani-garcia/vaultwarden] which connects to the Bitwarden app.

I think the iCloud password manager also works pretty well, provided you're using Apple products.

If you don't need to share passwords between people (other than manually), Firefox Sync is perfect.

The closest I've found is Bitwarden, but even that isn't quite as good as 1Password.
