Vaultwarden has been running on a Raspberry Pi Zero in a drawer for a year, and it's the most underrated thing I host

Running Vaultwarden on a Raspberry Pi Zero 2W as a self-hosted password manager is a low-cost, low-power alternative to cloud-based services like LastPass. The setup uses DietPi (skipping Docker to conserve resources), the Bitwarden browser extension pointed at the local server, and Tailscale for secure remote access. The Pi Zero 2W draws under a watt, can run off a power bank, and handles Vaultwarden's lightweight workload comfortably. The result is full Bitwarden feature parity — password generator, 2FA, vaults, autofill — with no monthly subscription and no third-party data exposure.
