Are you a Linux enthusiast who's been waiting for a truly integrated VPN experience? Well, the wait is OVER! Proton VPN, a champion of privacy and security, has finally delivered a fully functional command-line interface (CLI) for Linux users. This is huge! But here's where it gets controversial... some might say it's about time!
Proton VPN (partner link) has earned a solid reputation as one of the most trusted VPN services available. They're known for their strong commitment to user privacy, offering a free plan, strict no-logs policies, and open-source apps across multiple platforms. This dedication to security and transparency makes Proton VPN a favorite among individuals who prioritize control over their online footprint. Think of it as having a digital bodyguard, ensuring your online activities remain private and secure.
For years, Linux aficionados have been vocal about their need for a robust command-line interface. While an earlier CLI existed, recent development efforts primarily focused on graphical user interface (GUI) applications. The Proton VPN team listened, and now, their prayers have been answered! This new CLI is more than just a convenience; it's a game-changer for Linux users who prefer the efficiency and control of the command line.
Proton VPN CLI App (Beta): A Deep Dive
The new CLI app empowers Linux users to seamlessly connect to and disconnect from VPN servers directly from their terminal. This means no more fumbling with desktop GUIs! Paid plan users get even more granular control, with the ability to select servers by country, city, or even specific server. The CLI is designed for speed and efficiency, providing a lightweight alternative to the desktop application. Imagine being able to secure your connection with just a few keystrokes – that's the power of the Proton VPN CLI.
It's important to remember that the CLI is currently in beta. This means it's still under development, and you might encounter a few quirks. Currently, it only supports the WireGuard protocol, a modern and secure VPN protocol. And this is the part most people miss... advanced features like NetShield (Proton VPN's ad and malware blocker), Kill Switch (which prevents data leaks if the VPN connection drops), Split Tunneling (allowing you to choose which apps use the VPN connection), and Port Forwarding are not yet implemented. Settings must be configured through config files, which might require a bit of manual tweaking. But don't worry! Proton VPN is taking a phased approach, focusing on delivering the core functionality first and then expanding features based on user feedback. This ensures a stable and user-driven development process.
The CLI announcement was part of Proton VPN's 2025-26 fall and winter roadmap. This roadmap also includes an exciting upcoming auto-launch feature for Linux. This feature will allow the VPN to automatically start when your system boots up, ensuring you're always protected from the moment you log in. It's like having an always-on security shield!
But the good news doesn't stop there! Beyond the CLI, Proton VPN (partner link) is also implementing a new network architecture designed to deliver even faster speeds, improved reliability, stronger resistance to censorship, and even post-quantum encryption. This means your data will be protected against even the most advanced threats of the future. Free-tier users are also getting some love, with new server locations in Mexico, Canada, Norway, Singapore, and more. This expansion of server locations provides free users with more options for bypassing geo-restrictions and accessing content from around the world.
How Does it Hold Up in the Real World?
I decided to put the new CLI to the test on my Ubuntu 25.10 system. I'll be honest, the initial setup was a little challenging, especially for someone like me who's more accustomed to using GUIs. But after running protonvpn -h, I was able to quickly figure out how to sign in and connect to servers. The -h command is your friend! It displays a helpful list of available commands and options.
Once I was connected to their Seattle server, I ran a speed test using fast.com. I was blown away! I was getting speeds very close to what my usual 300 Mbps fiber connection provides (and keep in mind, I'm located in India!). This was incredibly impressive, demonstrating the CLI's speed and efficiency.
Ready to Give it a Try?
You can test out this early version of the Proton VPN CLI for Linux by following one of the official guides linked below:
Make sure you first install the "Beta" Linux app as described in the guides above. Once that’s done, run the additional command listed below for your specific distro to get the CLI client.
- Debian/Ubuntu:
sudo apt update && sudo apt install proton-vpn-cli - Fedora:
sudo dnf check-update --refresh && sudo dnf install proton-vpn-cli
To launch the CLI, simply type protonvpn in your terminal.
If you're using a different distribution, the CLI might work if it's based on one of the distributions listed above (for example, an Ubuntu derivative). However, Proton VPN doesn't officially guarantee compatibility. So, are you feeling adventurous? Give it a shot and let me know how it goes in the comments below! I'm curious to see if it works on other distros.
