Vaultwarden
Lightweight, Bitwarden-compatible password manager server written in Rust, prized for its tiny resource footprint and drop-in compatibility with official Bitwarden clients. Widely regarded as one of the best-engineered self-hosted security tools.

⚙ Full Stack
Single statically-linked Rust binary implementing the Bitwarden API surface, backed by SQLite in WAL mode by default (Postgres/MySQL also supported), with all encryption handled client-side per Bitwarden's zero-knowledge model.
📈 Scaling Analysis
Extremely efficient at any single-instance scale thanks to Rust and SQLite WAL mode, and can move to Postgres for true multi-instance horizontal scaling; the zero-knowledge encryption model means server-side scaling never touches sensitive plaintext, which is the core of its excellent security posture.
🚀 Running on Nexlayer
Single app pod with a persistent volume for the SQLite database is enough for most teams; for heavier concurrent write load switch DATABASE_URL to a postgres pod (postgres.pod:5432). Mirror the Rust-based image via mirror.gcr.io and set DOMAIN to the public HTTPS URL for WebAuthn/U2F to work.
