Best VPN for Raspberry Pi: ARM-Optimized Picks
Find the best VPN for Raspberry Pi with native ARM support and lightweight clients. We review top picks optimized for your Pi's limited resources.
Top VPNs for Raspberry Pi
Bottom Line: A VPN on Raspberry Pi encrypts your internet traffic and lets you access geo-restricted content. The Pi’s ARM processor and limited RAM demand a lightweight provider with native ARM support for reliable performance.
Raspberry Pi owners face a unique challenge when choosing a VPN. Unlike standard Linux desktops, the Pi runs on low-power ARM hardware with as little as 256 MB of RAM. That means heavy VPN clients designed for x86 systems can choke performance. You need a provider that offers lightweight ARM-compatible binaries or clean OpenVPN configuration files.
This guide focuses on what makes the Pi different from other Linux devices. We cover ARM-specific compatibility, real-world performance on constrained hardware, and step-by-step CLI setup. If you use your Pi as a dedicated router or ad blocker, check our router VPN guide instead.
Why ARM Hardware Changes Your VPN Choice
Standard VPN apps built for Linux often assume multi-core x86 processors and 4+ GB of RAM. The Raspberry Pi 1 runs a single-core 700 MHz ARM chip with 256–512 MB of RAM. Even newer Pi models (Pi 4, Pi 5) use ARM processors that handle encryption differently than desktop CPUs.
This matters because VPN encryption is CPU-intensive. OpenVPN on a Pi 1 typically delivers 5–15 Mbps throughput. WireGuard performs better, reaching 25–40 Mbps on a Pi 4 due to its lighter codebase. Choosing the right protocol can double or triple your usable bandwidth.
ARM Compatibility Checklist
Before picking a VPN, verify three things:
- Native ARM binaries: Does the provider offer a compiled client for armhf or arm64?
- Manual OpenVPN/WireGuard support: Can you download .ovpn or WireGuard config files directly?
- CLI-only operation: GUI clients waste RAM. Command-line setup preserves resources for your actual projects.

How to Install a VPN on Raspberry Pi (CLI Method)
Most VPN providers work on Raspberry Pi through OpenVPN or WireGuard. Here is the OpenVPN method, which works with every provider on our list.
Step 1: Update Your System
Open a terminal and run:
sudo apt-get update && sudo apt-get upgrade
Step 2: Install OpenVPN
sudo apt-get install openvpn
For WireGuard (Pi 2 and newer recommended):
sudo apt-get install wireguard
Step 3: Download Your Provider’s Config Files
Visit your VPN provider’s website. Download the OpenVPN (.ovpn) or WireGuard (.conf) configuration files for your chosen server location.
Step 4: Move Config Files to the Correct Directory
sudo cp /path/to/your/config/files/*.ovpn /etc/openvpn/
Step 5: Connect to the VPN
sudo openvpn /etc/openvpn/your-config-file.ovpn
Enter your VPN credentials when prompted.
Step 6: Verify Your Connection
curl ifconfig.me
This command returns your current public IP address. If it shows your VPN server’s IP instead of your home IP, the connection works.
Optional: Auto-Start VPN on Boot
To run the VPN automatically when your Pi boots:
sudo systemctl enable openvpn@your-config-file
This ensures your Pi stays protected even after a power cycle or reboot.

Key Benefits of Running a VPN on Your Pi
Encrypt All Traffic on Constrained Hardware
A VPN encrypts every packet leaving your Pi. This protects data from interception on shared or public networks. Even a Pi 1 handles basic encryption without issue at lower speeds.
Access Region-Locked Content
Connect to servers in different countries to access streaming libraries, websites, or services blocked in your region.
Prevent ISP Throttling
Your ISP cannot throttle traffic it cannot inspect. VPN encryption prevents deep packet inspection, maintaining consistent speeds for downloads and streaming.
Secure Remote Access to Your Pi
If you access your Pi remotely via SSH, a VPN adds a security layer. Only devices connected to the same VPN network can reach your Pi’s services.
Run Pi-Hosted Services Privately
Running a personal web server, file server, or development environment on your Pi? A VPN prevents your home IP from being exposed to the public internet.

NordVPN leads for overall performance thanks to its NordLynx protocol and native ARM CLI app. Surfshark wins on value with unlimited device connections. ProtonVPN is the strongest pick for open-source transparency. PIA gives advanced users the most configuration control.
Install WireGuard whenever possible. It cuts CPU usage and doubles throughput compared to OpenVPN on ARM chips. Follow the CLI setup steps above, and your Pi will be encrypted and connected in under 10 minutes.
Frequently Asked Questions
How does Raspberry Pi’s ARM hardware change which VPN you should pick?
Pi models run on low-power ARM chips instead of x86, and VPN encryption is CPU-intensive, so heavy desktop-style clients bog down the limited processor. A Pi 1’s single-core 700 MHz chip with 256-512 MB RAM strains under OpenVPN, while WireGuard-based protocols use less CPU. Look for native ARM binaries or clean OpenVPN/WireGuard config files rather than a bloated GUI app.
Should I use WireGuard or OpenVPN on my Raspberry Pi?
WireGuard, whenever your provider supports it. It uses a lighter codebase that roughly doubles throughput over OpenVPN on constrained ARM chips, even on an original Pi 1. NordVPN’s NordLynx, a WireGuard-based protocol, cuts CPU overhead by 40% compared to OpenVPN, which matters most on Pi 1 and Pi 3 boards with limited processing headroom.
Does a VPN perform the same across every Raspberry Pi model?
No, performance scales with each Pi’s hardware. The Pi 1’s 700 MHz single-core chip and 256-512 MB RAM suit only light browsing and 480p streaming, the Pi 3’s 1.2 GHz quad-core handles 720p, and the Pi 4’s 1.5 GHz quad-core with 2-8 GB RAM manages 1080p and most tasks without bottlenecking. The Pi 5 approaches desktop-class VPN performance.
How do I set up a VPN on Raspberry Pi from the command line?
Update your system with apt-get update && apt-get upgrade, then install openvpn or wireguard via apt-get. Download your provider’s .ovpn or .conf files, copy them into /etc/openvpn/, and connect with sudo openvpn followed by your config filename. Enable systemctl on boot so the tunnel reconnects automatically after a power cycle or reboot.
How do I confirm my Raspberry Pi is actually routed through the VPN?
Run curl ifconfig.me in the terminal after connecting. If it returns your VPN server’s IP address instead of your home ISP’s IP, the tunnel is active. This CLI check works with any provider’s OpenVPN or WireGuard config and avoids running a GUI client, which wastes RAM that constrained Pi models need for other processes.
What if my VPN provider doesn’t offer a native ARM client?
ExpressVPN, for example, has no native ARM app but provides manual OpenVPN configuration files that work cleanly through the standard OpenVPN package on any Pi model. Install openvpn via apt-get, drop the downloaded .ovpn file into /etc/openvpn/, and connect manually; you lose the CLI app’s convenience but not functionality or connection stability.
What should I do if my Pi struggles to keep up with VPN encryption?
Switch protocols first. OpenVPN taxes a Pi 1’s single-core 700 MHz chip heavily, while WireGuard uses a lighter codebase that eases the load on the same hardware. If you’re on Pi 1 or Pi 3, expect basic browsing and lower-resolution streaming rather than 1080p; upgrading to a Pi 4 or 5 raises the ceiling substantially.
How many devices can one VPN account cover if I’m also running it on my Pi?
It depends on the provider. Surfshark allows unlimited simultaneous connections, so your Pi and every other household device run under one account. NordVPN caps at 10 simultaneous devices, and ExpressVPN allows 10 to 14 depending on the plan tier. If your Pi is one of several devices, Surfshark’s unlimited model avoids counting against a cap.
Which VPN is the best value for a Raspberry Pi setup?
Surfshark is the cheapest entry point, from $1.99/month on its longest-term plan, and its unlimited device connections mean your Pi doesn’t eat into a device cap. NordVPN and ExpressVPN both start from $3.49/month on their longest-term plans but cap devices at 10 and 10-14 respectively. For a Pi plus a full household, Surfshark’s model fits better.
What if a VPN doesn’t perform well on my specific Pi model?
All three top picks, NordVPN, ExpressVPN, and Surfshark, back their plans with a 30-day money-back guarantee, so you can test actual throughput on your Pi 1, 3, 4, or 5 before committing long-term. Since performance varies significantly by hardware generation, use that window to confirm your chosen protocol and provider combination actually meets your needs.
Is a VPN enough to secure remote SSH access to my Raspberry Pi?
A VPN adds a meaningful security layer by ensuring only devices connected to the same VPN network can reach your Pi’s exposed services, including SSH. It encrypts traffic end to end, which protects against interception on shared or public networks. Pair it with strong SSH key authentication rather than relying on the VPN alone for full protection.
Can I run ProtonVPN’s free tier on my Raspberry Pi?
Yes. ProtonVPN’s Linux CLI app supports ARM architecture and works with its free tier, making it the only free option among the providers covered here with a documented ARM path. Its entire codebase is open source and audited by SEC Consult, appealing to Pi users who want to verify exactly what’s running on constrained hardware before upgrading to paid.
Which VPN delivers the best real-world speed on Raspberry Pi hardware?
NordVPN, whose NordLynx protocol is WireGuard-based and cuts CPU overhead by 40% versus OpenVPN, a meaningful difference on ARM chips with limited processing headroom. NordVPN ranks #1 of 22 in our Speed Lab, aggregated from independent labs, and offers a native Linux CLI app with ARM support, so that performance edge carries over to Pi 4 and Pi 5 boards.
Can I stream through a VPN running on my Raspberry Pi without buffering?
It depends on your Pi model. A Pi 1 handles only basic browsing and light 480p streaming even with WireGuard, a Pi 3 manages 720p, and a Pi 4 with 2-8 GB RAM handles 1080p and most streaming tasks without bottlenecking. Choose WireGuard over OpenVPN on any model since it reduces CPU load and preserves more bandwidth for playback.
