Got too used to keeper at the old gig, and it was free at the time.

THIS looks to be just as good, but hosted.
We'll see

 

So far its great!
It uses the official BitWarden browser extensions and mobile apps, you just click the 'self-hosted' and add your base URL (at the top of this page)
Supports personal and Organization Vaults, so you can have shared logins for business uses.
Standard invite based sign-up, prep your user, select if they are allowed a personal vault or Organization Vault only, and done.
