Open source, very effective for personal use.
It provides a very clean integration with mobile application to sync passwords across devices.
I've experienced for professional use one of the leading vendors but I switched for my personal password manager to Bitwarden and I also suggested it to my friends.

Love this app. Makes life much easier, and I feel more secure using it.

This vault is so perfect, i love it.

Great password manager and competent Firefox addon :)

very good

Very nicely integrated interface for Bitwarden.
