Best VPN for Linux in 2026: Six options compared by app and price

The best VPN for Linux is the one that gives you a client you can install and keep updated on your distribution, a kill switch that blocks traffic when the tunnel drops, and a price you can keep paying. A VPN, or virtual private network, sends your traffic through an encrypted connection to the provider's server, which hides your traffic from the local network and masks your IP address from the sites you visit. Six providers come up most often in 2026 reviews, and each one gives up something in exchange for its strengths.

How we picked the six options

Linux support varies more than vendor marketing suggests. Each entry below was checked against the criteria that matter on a desktop or server:

• A native graphical app or a command-line client that installs on mainstream distributions such as Ubuntu, Debian, and Fedora.
• A kill switch, the setting that cuts internet access if the VPN connection drops.
• WireGuard support, the modern protocol that reviewers now test first for speed.
• A published price for the cheapest plan, with the monthly rate on the longest contract shown separately.
• The number of simultaneous devices and the length of the refund window.

Prices move often, and the figures below come from 2026 reviews by Tom's Guide, Security.org, and All About Cookies. Promotional rates usually apply to the first term only, so check the provider's pricing page before you pay. Use a VPN only in line with the provider's terms and the rules that apply to you.

Proton VPN: an open-source Linux client with a free tier

Proton VPN stands out because its Linux app is fully open source, so security-minded users can read the code. Its free plan also works with the native app, which makes it the easiest way to test a Linux VPN without paying.

Pros

• The open-source client lets you verify what the app does.
• The free plan lets you test the native app before you pay.
• The native package supports Proton's protocols on full desktops.

Cons

• The Snap version lacks Proton's own protocols, split tunneling, and ARM support, so a full desktop needs the native package.
• The low price requires a one- or two-year commitment.

Mullvad: flat pricing and no personal details

Mullvad is a privacy-first provider that offers both a graphical app and a command-line client on Linux. It uses WireGuard exclusively since January 2026, after retiring OpenVPN, according to Security.org.

Pros

• The flat price means no renewal increases and no discount for commitment.
• Sign-up needs no email address, and reviewers note that payment by cash or cryptocurrency is possible.
• The graphical app and command-line client both cover Linux.

Cons

• The flat rate is more expensive than the discounted long-term plans from rivals.
• Reviewers from All About Cookies say it struggles with streaming services other than Netflix.
• Reviews disagree on the refund window, so confirm the current term before you buy.

NordVPN: the most complete desktop option

NordVPN was one of the first VPNs to support Linux. Tom's Guide reports that it recently replaced its terminal interface with a desktop app, while some reviewers still rate the command-line client as the more complete tool.

Pros

• The desktop app covers the day-to-day features most Linux users need.
• The 30-day refund window lets you test the service with less risk.
• It supports ten simultaneous devices on one account.

Cons

• The lowest price is a promotional rate for the first term, and renewal costs more.
• The monthly plan is one of the most expensive options in this list.

ExpressVPN: easy setup at a premium price

ExpressVPN is the option many reviewers pick for a simple setup. Reviews disagree on the Linux client, though. Tom's Guide says the service has no graphical app right away and relies on a browser extension, while Cybernews describes both a command-line app and a native graphical app.

Pros

• Setup is quick, and the app is easy to use for beginners.
• Reviewers praise its streaming access and customer support.

Cons

• It sits at the premium end of the price range.
• The device allowance appears in more than one form on the provider's pages, so confirm it before you sign up.

Windscribe: a usable free tier with a graphical client

Windscribe offers a compact graphical app on Linux and a free plan. The free plan includes a 10 GB monthly data limit, according to a 2026 review on Experte.

Pros

• The free plan works without a payment method.
• The graphical app includes LAN connection options and obfuscated protocols, per Tom's Guide.

Cons

• Tom's Guide reports only a 7-day refund period on paid plans, which is short for testing.
• The 10 GB cap runs out quickly if you stream or download large files.

Private Internet Access: configurable and cheap on long plans

Private Internet Access, often called PIA, supports both a graphical and a command-line client on Linux. Its three-year price is among the lowest in this list, though that rate requires a long commitment.

Pros

• The configuration options give advanced users fine control over connections.
• The three-year plan offers strong value for long-term users.

Cons

• The configuration options can overwhelm beginners who only want a connect button.
• Vpn-picker describes its open-source status as partial, so it is not fully open source like Proton's client.

Which one fits you

Choose Proton VPN if you want an open-source client and a free plan to test first. Choose NordVPN or Private Internet Access if you plan to commit to a long term and want the lowest effective monthly price. A tight budget with a privacy focus points to Mullvad, since its flat rate avoids renewal surprises, but it does not suit heavy streaming.

Check each option against the device limit you need, then run the refund window before you commit.
