Bitwarden vs Vaultwarden
Vaultwarden is not a different password manager, it is a lightweight, unofficial server that speaks Bitwarden's protocol, so you use the same official Bitwarden apps against it. For self-hosting on a homelab, Vaultwarden is the popular choice: a tiny footprint that unlocks premium features for free. Official Bitwarden is the pick for businesses wanting vendor support, audits, or hosted service.

Side by side
| Bitwarden | Vaultwarden | |
|---|---|---|
| What it is | Official password manager (cloud or self-host) | Unofficial lightweight server, Bitwarden-compatible |
| Client apps | Official Bitwarden apps | The same official Bitwarden apps |
| Self-host footprint | Heavier (official server stack) | Tiny (single Rust binary) |
| Premium features self-hosted | Paid | Free (Vaultwarden unlocks them) |
| Official support | Yes | No (community project) |
| Hosting | Cloud or self-host | Self-host only |
| Audits / compliance | Official, audited | Community reimplementation |
| Best at | Support, business, hosted option | Light self-hosting with free premium |
First, the relationship
Bitwarden is the company: the official apps, the official server you can self-host, and the cloud service. Vaultwarden is a community project that reimplements the Bitwarden server in Rust. The important part is that Vaultwarden is compatible with Bitwarden's clients, so your browser extension, desktop app, and phone app are the official Bitwarden ones, just pointed at your server.
So you are not choosing between two password managers. You are choosing which server backs the same Bitwarden apps: the official one or the lightweight community one.
Why homelabbers pick Vaultwarden
Two reasons. First, footprint: Vaultwarden is a single small binary that runs in a tiny container, where the official self-hosted Bitwarden server is a heavier multi-container stack. On a homelab, Vaultwarden barely registers.
Second, cost: Vaultwarden unlocks Bitwarden's premium features (like advanced two-factor options and organization features) for free when you self-host, where the official server gates some of them behind a license. For a personal or family vault, that combination of light and free is why Vaultwarden dominates homelab setups.
When to use official Bitwarden
Choose the official option when trust and support matter more than footprint. A business storing other people's credentials wants an officially maintained, audited server, vendor support, and compliance documentation, which a community reimplementation does not provide.
It is also the right call if you would rather not self-host at all. Bitwarden's cloud is inexpensive, audited, and removes the maintenance entirely, while still letting you export and move later if you change your mind.
Security and trust
Vaultwarden is widely deployed and the encryption still happens in the official Bitwarden clients, which are zero-knowledge, so your server never sees your plaintext. That said, Vaultwarden is a community reimplementation and is not covered by Bitwarden's formal audits. Keep it behind a reverse proxy with HTTPS, do not expose it raw to the internet, and back it up.
For a personal or family vault on a homelab, that is a reasonable posture. For a business holding clients' secrets, the official, audited server is the more defensible choice.
Where Bitwarden wins
- Official, audited, and supported, with a cheap hosted cloud option.
- The right choice for businesses and compliance.
- You can self-host the official server too if you prefer.
Where Vaultwarden wins
- Tiny footprint: a single Rust binary in a small container.
- Unlocks Bitwarden's premium features for free when self-hosted.
- Uses the same official Bitwarden client apps.
Which to pick, by situation
| Your situation | Pick | Why |
|---|---|---|
| Personal or family vault on a homelab | Vaultwarden | Tiny footprint and free premium features, same Bitwarden apps. |
| Want free premium features self-hosted | Vaultwarden | It unlocks them at no cost when self-hosted. |
| Business needing support and audits | Bitwarden | Official, audited server with vendor support. |
| Do not want to self-host at all | Bitwarden | The audited cloud service removes the maintenance. |
The verdict
For self-hosting a personal or family password manager on a homelab, run Vaultwarden: it is tiny, unlocks premium features for free, and uses the same official Bitwarden apps. Choose official Bitwarden when you want an audited, supported server for a business, or when you would rather use the cheap audited cloud and not self-host at all. Either way, put a self-hosted vault behind a reverse proxy; see Caddy vs Nginx.
Choose Bitwarden if you want an official, audited, supported server, or a cheap hosted option, especially for a business.
Choose Vaultwarden if you are self-hosting a personal or family vault and want a tiny footprint with free premium features.

FAQ
Why use Vaultwarden instead of Bitwarden?
It is far lighter to self-host (a single Rust binary versus the official multi-container stack) and unlocks Bitwarden's premium features for free on your own server, while you keep using the official Bitwarden apps. For homelab self-hosting it is the popular choice.
Can I use the Bitwarden apps with Vaultwarden?
Yes, that is the whole point. The official Bitwarden browser extensions, desktop app, and mobile apps all connect to a Vaultwarden server by setting the server URL in the app's settings.
Is Vaultwarden safe?
The encryption happens in the official zero-knowledge Bitwarden clients, so your server never sees plaintext, and Vaultwarden is widely used. It is a community reimplementation and not covered by Bitwarden's formal audits, so keep it behind HTTPS, do not expose it raw to the internet, and back it up.
Is there anything better than Bitwarden?
Bitwarden, especially self-hosted via Vaultwarden, is one of the best options. Alternatives include KeePass (local encrypted files), Proton Pass, and commercial 1Password, each with different tradeoffs around self-hosting and convenience.
