| Feature | 1Password / LastPass | Bitwarden |
|---|---|---|
| Company structure | Proprietary US vendor | Open-source code, US-owned legal entity |
| EU hosting | Often managed-only | EU region or self-hosted EU deployment |
| Encryption model | Vendor-controlled in many cases | Client-side encryption with verifiable open-source clients |
| Source transparency | Closed | Source available with some BSL components |
Bitwarden is included in EU Stacks specifically because procurement decisions are often clearer when the alternatives include products with honest tradeoffs rather than only the cleanest European-owned options.
The open-source codebase, mature client ecosystem, and EU hosting region make Bitwarden the most operationally familiar option for teams transitioning away from LastPass or 1Password. End-to-end encryption with client-side key derivation provides strong cryptographic guarantees even against the operator.
The honest limitation is corporate structure: Bitwarden Inc. is a US legal entity, which means the US CLOUD Act applies. For organizations where vendor jurisdiction is the binding constraint, Passbolt is a cleaner choice. For organizations where encryption guarantees and operational maturity matter more, Bitwarden remains a credible option, especially when self-hosted.
Tools that typically complement this profile in a cleaner European software stack.
One of the most practical EU infrastructure defaults for startups that want predictable costs and regional clarity.
Public cloud and infrastructure platform for teams that want an explicitly European cloud provider with a modern product surface.
Open-source IAM for customer and workforce identity with OIDC, SAML, SCIM, and machine identity support.
Common questions about compliance, hosting, and capabilities.
Bitwarden is open-source software operated by Bitwarden Inc., a US corporation. The managed service offers an EU hosting region. Self-hosted deployments inside EU infrastructure remove the vendor data path entirely, though the upstream sponsor remains a US legal entity.
Bitwarden is hosted in US, EU, or self-hosted and headquartered in Santa Barbara, California, United States, operating under United States with EU hosting region available jurisdiction.
Yes, Bitwarden is open source under the GPL-3.0 / BSL for some server components license. It can also be self-hosted for full data control.
