I've been keeping my eye on AliasVault[1]. Open-source, self-hostable or pay for cloud hosting, handles both email aliases and passwords.

I'll probably switch for password management once it has a proper security audit, and for email aliases once (if) they implement IMAP/SMTP or similar so reading emails isn't restricted to in-app.
