Selfhosted Password Manager Question

Hey! I would like to selfhost a password manager but I can't decide which one to use. I am looking to use it only locally. I really like the UIs of Padloc and Passbolt. For passbolt to work properly I would need a mailserver, right? I do not want to set up a mailserver. Do I need one to selfhost Padloc?

I already tried to set up the Padloc Docker Container, but it gives me some errors. Maybe, there is another package for Padloc selfhost? Like a deb or snap package?

Do you have any other recommendations for which one to use? Maybe one thats NOT a docker container? Any other tips?

Thanks for reading this, looking forward to reading your answers & opinions! :)
