Its open source(https://github.com/bitwarden), so self hosting is possible as well => https://help.bitwarden.com/article/install-on-premise/
Disclosure: I've been using it for a year now. $10 per year paid plan. Just renewed again.
I use it across my iPhones and iPads, and all the major browsers on my Mac. Plus, my business partner and I have a shared vault in 1Password for commonly needed account passwords. It’s super useful.
