Proton VPN vs CyberGhost

Proton VPN gives you more ways to inspect, try, and route the service before you settle in. CyberGhost's clearest counterweight is a documented RAM-only server fleet.

The clients are open and the free plan keeps the first step simple

Proton VPN's client apps are open source across the supported platform set. Not all of CyberGhost's client apps are open source. Proton VPN has a continuing free plan. CyberGhost does not currently offer a continuing free plan. Those are separate advantages: one is about what you can inspect, the other is about trying the service without paying first.

Multi-hop is confirmed here too

Proton VPN has a confirmed multi-hop route in the current feature set. Built-in multi-hop is not part of CyberGhost's confirmed feature set. If chaining VPN hops is part of your routine, this is another concrete separator in Proton VPN's favor.

RAM-only is the clean infrastructure difference

CyberGhost's server fleet is documented as RAM-only. A full RAM-only fleet is not confirmed for Proton VPN. If avoiding persistent server storage is one of your explicit criteria, this is the part of the matchup that points toward CyberGhost.

Streaming guidance does not separate the pair

CyberGhost has streaming-focused server tools or labels, so you are not starting every stream with blind server roulette. Proton VPN has streaming-focused server tools or labels, so you are not starting every stream with blind server roulette. Both services already give you streaming-oriented guidance, so that shared convenience should not carry the decision.
