Vaultwarden vs Bitwarden: Side-by-Side Comparison

Core Differences at a Glance

Both use zero-knowledge encryption, meaning the server cannot read your passwords. Both work with official Bitwarden clients (iOS, Android, Web, Browser Extension, CLI, Desktop). The comparison table shows where they diverge.

Vaultwarden Wins for Individual Users and Small Teams

If you want all premium features without paying a subscription, Vaultwarden delivers. It reports every account as premium, unlocking TOTP, attachments, Emergency Access, Organizations, Collections, and role-based access control—features Bitwarden charges $19.80/year or more to unlock.

Vaultwarden runs on a Raspberry Pi or a $3-5/month VPS. A single Rust binary uses ~50 MB of RAM. Backups are trivial: one SQLite file. For personal vaults, families, and teams under 50 users, the lightweight footprint is a real advantage.

There is no vendor lock-in. Your data lives in SQLite, PostgreSQL, or MySQL on your server. If you decide to leave, export your vault and import it anywhere.

Bitwarden Wins for Enterprise and Regulated Teams

If you need SSO (Okta, Azure AD, Okta), directory sync, SCIM provisioning, or compliance certifications (SOC 2, HIPAA, GDPR, PCI-DSS), Bitwarden is the only choice. Vaultwarden has no built-in support for these.

Bitwarden Enterprise offers passwordless login, granular access controls, advanced audit logs, and professional support with an SLA. If your organization operates in healthcare, finance, or a regulated sector, these certifications matter.

Bitwarden also handles the operational burden for you. The cloud tier ($19.80/year Premium, $47.88/year Families) requires zero setup or maintenance.

Three-Way Consideration: KeePass and Others

Some users evaluate Vaultwarden alongside lightweight alternatives like KeePass (fully offline, no server) or Passbolt (team-focused, open source). KeePass wins on offline-first simplicity. Passbolt wins on team sharing without external infrastructure. Vaultwarden wins on syncing across devices with a single server. The choice depends on your sync and sharing needs.

Moving from Bitwarden to Vaultwarden (or Reverse)

Both servers use the Bitwarden API, so clients (iOS, Android, Web, Browser Extension) work with either. Migration is straightforward.

Export from Bitwarden:

1. Log in to Bitwarden Web Vault or desktop app
2. Go to Settings > Export Vault
3. Choose encrypted JSON (recommended) or plaintext CSV
4. Save the file locally

Import into Vaultwarden:

1. Deploy Vaultwarden (self-hosted or managed)
2. Log in to the new Vaultwarden Web Vault
3. Go to Tools > Import Data
4. Upload your exported JSON file
5. Your vault appears instantly

No data loss. The export is encrypted and contains everything: passwords, notes, cards, identities, attachments, organization data.

One caveat: Bitwarden organizations sometimes require manual role and collection adjustment after import due to differences in how each system structures team access. For personal vaults, import is seamless.

Going backward (Vaultwarden to Bitwarden Cloud)? The same process works in reverse. You are never locked in.

Vaultwarden is Better for:

• Personal users and families wanting all premium features without subscription
• Homelabs and self-hosting enthusiasts with operational skills
• Teams under 50 people seeking cost control and vendor independence
• EU organizations prioritizing data residency on their own servers

Bitwarden is Better for:

• Enterprise teams needing SSO, SCIM, and directory sync
• Organizations in regulated industries (healthcare, finance) requiring compliance audits
• Users who want zero setup or maintenance (Bitwarden Cloud)
• Teams prioritizing official commercial support and SLAs

Both encrypt your passwords client-side. Both are trustworthy. The choice hinges on your operational comfort, team size, and compliance requirements. If you choose Vaultwarden, Opsily's managed hosting eliminates the self-hosting burden—you get the cost and control without the ops tax.
