The only info i can find on this is here: Protonvpn roadmap 2025-2026
- does not say it is released and future tense around Linux CLI.
- no sourcecode on cli on github
- author probably got confused with community protonvpn CLI project
Edit- but that screenshot shows protons support link… 🤔🤔🤔
I managed to find this from the official reddit account: https://www.reddit.com/r/ProtonVPN/comments/1oj8u5y/the_official_proton_vpn_commandline_interface_cli/
It’s “early access” still, but publicly available.
Haven’t researched if it’s closed or open source, but either way I don’t see any benefit in using this instead of vanilla wireguard cli client (with proton conf file). At least for that one we know it is open source and thoroughly vetted.
Of course, the benefit of the Proton VPN CLI over Wireguard is ease of switching between any of the hundreds of servers when YouTube has blocked one again.
I agree that it’s not an improvement from a security perspective.
I think it will be easier to use features like port forwarding and split tunneling
- On a security note, you don’t leave your conf file with your secret key
