Secure credentials storage, hw inventory and organization

From a sysadmin and IT consultant point of view, is there a good open source solution that securely stores personal or client credentials that can be easily searchable and organized by company or category. Hardware inventory would be nice to have. I asked ChatGPT but the options it gave me are too complex and troublesome to setup. I would spin this in a VM (Linux is fine) and web based interface would be ideal.

I have used KeePass in the past and its good but I need to have a client installed with a connection to a private storage where the DB lives. I don't plan to store these creds on Dropbox or any commercial storage.

I have BitWarden for passwords, but organizing that is not very user friendly, also no inventory option.

Thx
