Choosing the Right VPN for KaOS

KaOS is a rolling-release distribution focused on KDE/Qt, using pacman as its package manager and shipping exclusively with modern Plasma Desktop environments. Its target audience is seasoned Linux users who appreciate a tightly integrated Qt ecosystem and an all-in-one repository model—there’s no AUR or external repos. Because of this, the ideal VPN for KaOS will:

• Offer a native Qt-based GUI or a standalone binary/AppImage (to avoid dependency conflicts).
• Provide robust Linux support (ideally an official Linux client, not just shell scripts).
• Be easy to install via pacman or as an executable AppImage, without pulling in bulky GTK stacks.
• Support OpenVPN and WireGuard, since these are available out of the box in KaOS’s repos.

After evaluating compatibility, user experience under Plasma, and ease of deployment on a pacman-only distro, the top contenders for KaOS are:

• Mullvad VPN – official Qt-based AppImage, open-source client, WireGuard OpenVPN support.
• ProtonVPN – open-source CLI, easy to script, strong privacy policy.
• Private Internet Access – well-known provider, offers a Linux installer script, OpenVPN WireGuard support.

Comparison Table

Installing and Configuring Mullvad VPN

Mullvad provides a statically-linked Qt AppImage, perfect for KaOS. It won’t interfere with your system libraries.

• Download the AppImage from the official site.
• Make it executable, then run the GUI or control it via CLI.

# 1. Download the latest Mullvad AppImage
wget https://mullvad.net/download/app/static/latest/mullvad-vpn.AppImage -O mullvad.AppImage

# 2. Make it executable
chmod  x mullvad.AppImage

# 3. (Optional) Move to /usr/local/bin for global access
sudo mv mullvad.AppImage /usr/local/bin/mullvad

# 4. Run the GUI
mullvad

Once the GUI launches, enter your account number (or create one anonymously), then click “Connect.” You can also use the CLI:

# Connect to the fastest server via CLI
mullvad connect

# List available servers
mullvad relay list

# Connect to a specific country code, e.g. US
mullvad connect us

Installing and Configuring ProtonVPN

ProtonVPN’s official client is a Python-based CLI that installs easily on KaOS. It leverages NetworkManager, so it integrates nicely with Plasma’s connection widget.

# 1. Install prerequisites via pacman
sudo pacman -S --needed python-pip python-setuptools

# 2. Install the ProtonVPN CLI
pip3 install protonvpn-cli

# 3. Initialize ProtonVPN (follow prompts: username, password, OpenVPN/WireGuard)
protonvpn init

# 4. Connect to the fastest server
protonvpn c

# 5. To disconnect
protonvpn d

After initialization, you can script connections or use protonvpn --help to see advanced options (select protocol, set up auto-connect, etc.).

Installing and Configuring Private Internet Access

PIA offers a convenient shell installer that sets up both GTK and CLI tools. Note: this pulls in some GTK dependencies, but it remains lightweight on KaOS.

# 1. Download and run the PIA installer script
curl -O https://installers.privateinternetaccess.com/download/pia-linux-install.sh
chmod  x pia-linux-install.sh
sudo ./pia-linux-install.sh

# 2. Launch the UI or CLI
#  GTK GUI:
pia-client
#  CLI:
piactl login
piactl connect

Once installed, you can control PIA from the system tray or via the piactl commands. For KDE users, pin the tray icon in Plasma for quick access.

Final Thoughts

On KaOS, the best VPN experience comes from choosing tools that respect your Qt-only setup and roll easily through pacman or standalone binaries. Mullvad leads with a seamless Qt AppImage, ProtonVPN offers a polished CLI well integrated with NetworkManager, and PIA brings a battle-tested installer script. Pick the one that suits your workflow, configure it once, and enjoy secure browsing on your Plasma desktop.
