Quick verdict
| Your primary need | Buy this |
|---|---|
| A self‑hosted password manager that feels like Bitwarden but runs on a tiny footprint. | Vaultwarden(affiliate) |
| A lightweight SSO/Identity gateway with built‑in 2FA for protecting web apps. | Authelia(affiliate) |
If you’re juggling both passwords and single sign‑on, many homelabbers end up running the two side by side – they complement rather than compete.
Spec‑by‑spec comparison
| Feature | Vaultwarden | Authelia |
|---|---|---|
| Category | Password (self‑host) | SSO/Identity |
| Type | Software | Software |
| Price | Free | Free |
| Best for | Self‑host Bitwarden | Lightweight self‑host SSO |
| Pros | Light, full features | Light, 2FA, free |
| Cons | You maintain it | Config‑heavy |
Both are open‑source and cost nothing to download. The real differences lie in what they protect (password vault vs authentication gateway) and how much configuration effort you’re willing to invest.
Deep dive
What each tool actually does
Vaultwarden is a community‑driven implementation of the Bitwarden server API. It gives you all the features you expect from Bitwarden – collections, organizations, password generation, secure notes – but runs on far less hardware than the official service. In practice it means you can drop it into a single Docker container on a Raspberry Pi or an old laptop and have a fully functional vault for your family or small team.
Authelia, by contrast, sits in front of whatever web services you expose (nginx, Traefik, Caddy, etc.) and forces users through a login flow before they reach the downstream app. Its “lightweight” claim is literal: it doesn’t try to be an identity provider with full OAuth2 or SAML stacks; instead it focuses on password‑based authentication plus optional two‑factor methods (TOTP, WebAuthn). The result is a fast, low‑overhead gatekeeper that works well for internal tools, homelab dashboards, and even personal media servers.
Ease of deployment & maintenance
From my experience, Vaultwarden wins the “just get it running” race. A single docker run line pulls down an image that’s ready to serve HTTPS (with a reverse proxy) or plain HTTP for testing. The only ongoing responsibility is keeping the container updated and backing up the SQLite database – nothing more complicated than copying a file.
Authelia feels like setting up a small firewall rule set. You must write a YAML configuration that describes your authentication backend, password policies, 2FA providers, and how each protected resource maps to an access level. That config can be version‑controlled, but the learning curve is steeper; you’ll spend more time reading docs than typing commands.
Security posture
Both projects are open source, meaning you can audit the code yourself or rely on community scrutiny. Vaultwarden inherits Bitwarden’s security model – end‑to‑end encryption of vault data before it hits disk. The biggest risk is operational: if you forget to rotate secrets or expose the service without TLS, your passwords could be compromised.
Authelia adds a layer of defense by requiring authentication before any downstream app even sees traffic. Its built‑in 2FA support raises security beyond simple passwords. However, because it’s config‑heavy, misconfiguration (e.g., leaving an endpoint unprotected) can create blind spots. The “you maintain it” con for Vaultwarden and the “config‑heavy” con for Authelia are two sides of the same coin: both demand vigilance.
Pros & cons
Vaultwarden
Pros
- Light on resources; runs comfortably on a Pi or cheap VPS.
- Full Bitwarden feature set (collections, password sharing, secure notes).
- Completely free and community‑maintained.
Cons
- You’re responsible for backups, updates, and TLS termination.
- No built‑in SSO capabilities – it only stores passwords.
Authelia
Pros
- Light footprint while providing 2FA out of the box.
- Free and open source; integrates with popular reverse proxies.
- Acts as a gatekeeper to any web service you choose.
Cons
- Configuration can be intimidating for newcomers.
- Does not store passwords itself – it only verifies identities.
Which should you buy (or rather, install)?
If your homelab’s biggest pain point is “I need a secure place to stash all my logins and generate strong passwords,” go with Vaultwarden. It gives you the familiar Bitwarden UI without paying for cloud storage, and its minimal hardware demands let it live on almost any box you already have.
If you’re more concerned about protecting web applications – say you run Home Assistant, Plex, or a private Git server behind a reverse proxy – then
