The real question
This is not a "best password managers 2026" ranking. The decision is: when is self-hosting a password vault a rational choice, and when should you keep a maintained SaaS vault?
A vault you cannot open on travel is a liability. Control of ciphertext does not cancel availability, backup, and recovery work.
Who should self-host a password manager
Self-host when you want ciphertext on disks you control, accept monthly update/backup duty, can put HTTPS in front of a single service, and have a written recovery path for another adult in the household.
Good fit: LAN-first households, operators already running a reverse proxy, people who distrust subscription lock-in and will actually export/test restores.
Who should NOT self-host
Skip self-hosting if nobody will patch the host, if travel unlock must work with zero ops, if you cannot store an encrypted offsite copy of the vault data, or if emergency access would live only in your head.
SaaS (Bitwarden cloud, 1Password, etc.) wins when device replacement must work in minutes and you will keep export habits without running Compose.
Threat model (plain language)
Decide who you defend against: credential stuffing, a stolen laptop, a curious roommate, a compromised vendor, or household members who should not see every entry.
Self-hosted Vaultwarden-class stacks keep vault ciphertext on your disk; the vendor does not hold the master password. SaaS vendors still hold infrastructure and metadata even with end-to-end encryption.
Neither choice fixes phishing. Both need unique passwords, MFA on the vault account, and browsers that do not autofill lookalike domains.
