Also searched as Proton Pass vs Vaultwarden — same comparison, one verdict.

Next step: Leaving 1Password? Move your vault to Vaultwarden
Vaultwarden
A lightweight, self-hosted Bitwarden-compatible server.
Vaultwarden is a resource-light server that speaks the Bitwarden protocol, so you run your own vault backend and use the official Bitwarden clients against it. It fits on the smallest VPS or a homelab box.
Proton Pass
End-to-end encrypted password manager from the Proton privacy suite.
Proton Pass is a hosted, end-to-end encrypted password manager (passwords, passkeys, 2FA codes, and hide-my-email aliases) from the Swiss privacy company Proton. Its apps are open-source and independently audited, but the service runs on Proton's servers — you can't self-host it. It's the easy, no-server option for people who want strong privacy without running infrastructure.

Weighing both against staying on 1Password? Is 1Password free? What it actually costs →
Vaultwarden
Strengths
- +Runs on tiny hardware
- +Works with official Bitwarden apps
- +You fully own the vault data
Trade-offs
- −You are responsible for backups and TLS
- −Unofficial (community) server
Proton Pass
Strengths
- +End-to-end encrypted — Proton cannot read your vault
- +Open-source, independently audited client apps
- +Zero setup — no server to run or maintain
- +Includes passkeys, 2FA, and hide-my-email aliases
Trade-offs
- −Hosted on Proton's servers — you cannot self-host it
- −The service itself is proprietary; only the client apps are open
- −Your vault lives in Proton's cloud, not on hardware you own
- −Full features require a paid plan
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Vaultwarden
if you want the source and the option to fork it, and you would rather run it on your own hardware, and your data should stay on machines you control.
Choose Proton Pass
if end-to-end encrypted — Proton cannot read your vault.
Neither, yet
if both carry a real cost you should weigh first — you are responsible for backups and TLS, and hosted on Proton's servers — you cannot self-host it. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.
Vaultwarden vs Proton Pass — common questions
Is Vaultwarden a better fit than Proton Pass for password managers?
It depends on what you are optimising for, and the honest split is this: Vaultwarden scores 95 to Proton Pass's 62 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Proton Pass earns its place on a different axis — end-to-end encrypted — Proton cannot read your vault. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Vaultwarden keeps its data local or in open formats, so leaving is an export rather than a negotiation. Proton Pass keeps your data on its own infrastructure, which is the part to plan for: confirm the export path before you commit, not when you are already trying to leave.
Can I self-host Vaultwarden?
Vaultwarden can be self-hosted; Proton Pass cannot, so it stays on the vendor's infrastructure whatever you do.
Are Vaultwarden and Proton Pass both alternatives to 1Password?
Yes — both appear in our 1Password comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off 1Password and now choosing between the two replacements, which is a narrower and much easier question.
