Psono

Psono is aimed at teams and organizations that want to run their own password manager rather than rely on a third party. Both the client and server are open source and secrets are end-to-end encrypted on your device before they ever reach the server so a hosting admin never sees plaintext credentials. You can self-host the Community edition for free, or pay for a managed cloud instance if you’d rather not run infrastructure. It’s made by a German company and passed a Cure53 audit in 2026, with no finding rated above low severity. It’s more involved to set up than consumer apps so it makes most sense for businesses and technically confident self-hosters.
