Proton VPN vs NordVPN

Proton VPN and NordVPN overlap on the everyday VPN basics, so this one is easier if you separate “what can I inspect?” from “what architecture do I want underneath me?”. That is a much more useful starting point than treating two broad feature lists as a popularity contest.

More to inspect for yourself

Proton VPN's client apps are open source across the supported platform set. Proton VPN has a continuing free plan. If your trust test includes looking at the client side rather than only accepting a vendor description, those two details are unusually relevant here. The free route also lets you try the service without turning the comparison into a purchase decision first.

What you give up in this matchup

A full RAM-only fleet is not confirmed for Proton VPN. NordVPN's server fleet is documented as RAM-only. So if the server-storage model is the thing you care about most, the difference is not cosmetic; it points the other way.

A stronger server-side argument

The RAM-only fleet described above is the cleaner reason to lean toward NordVPN if you would rather have the infrastructure design do more of the trust work for you.

The transparency trade-off

NordVPN's full no-logs audit is not currently available as an open-access report. Not all of NordVPN's client apps are open source. Those do not erase the rest of NordVPN's evidence, but they matter if your deciding habit is “show me the report and the client code without extra friction.”
