Vaultwarden

Open source · OSI-approvedStatus: unknown

Lightweight password vault server for Bitwarden clients

Vaultwarden reimplements the Bitwarden server API in Rust so that it runs comfortably on a Raspberry Pi or a small VPS, while the official Bitwarden desktop, mobile, and browser clients connect to it unchanged.

That combination is unusual: you get maintained, audited client applications with a server small enough to run at home, and no subscription for the features that are normally paid.

Decisive facts

  • Works with the official Bitwarden clients on every platform
  • Organisations, collections, and sharing without a paid tier
  • Runs in a container measured in tens of megabytes
  • Attachment storage, TOTP, and emergency access
  • SQLite, MySQL, or PostgreSQL backends

RustDesk is remote desktop software where the relay server is a binary you can run yourself. That is the whole argument: the same convenience as the commercial tools, without your screen sessions transiting a vendor's infrastructure.

Ente stores photos and videos encrypted on the client, so the server holds ciphertext it cannot read. Sync, albums, and sharing all work on top of that constraint rather than around it.

LicenseUnknown

Hanko is an authentication service built passkey-first rather than passkey-eventually. Passwords are optional from the start, and the hosted components handle the awkward parts of the WebAuthn ceremony that teams usually get wrong.
