Proton Unlimited alternatives
2 open-source projects that already do this job. Free to use - not free to run, which is what the numbers on the right are for.

What you give up either way
- Brand recognition and trust of Proton
- Independent security audits and broad open-source ecosystem maintained by Proton
- Regulatory positioning and Swiss legal protections
- Scale (global VPN servers, multi-product integration, and large-user reliability)
- Integrated additional services in the bundle (VPN, Pass, Lumo AI)
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Proton Unlimited, and it does not prove anyone has run it for a month. How we decide.
