This Shouldn’t Be Better Than 1Password… But It Is

VaultWarden is a lightweight, Rust-based, open-source reimplementation of Bitwarden that can be self-hosted on your own machine using a single Docker Compose file. It uses under 100MB of RAM, supports full end-to-end encryption, works with all official Bitwarden clients (browser extension, mobile app, CLI), and costs nothing. The setup involves running one Docker container, pointing the Bitwarden browser extension to localhost, and optionally using the Bitwarden CLI to pull credentials in scripts and CI/CD workflows. Trade-offs include responsibility for your own backups and updates, but Docker makes maintenance straightforward.
