Question 1

What VPN is best for software developers in 2026?

Accepted Answer

Mullvad is the top choice for developers who prioritise transparency and technical capability — its client is fully open-source, it runs RAM-only servers, accepts anonymous payment, and publishes detailed infrastructure documentation. ProtonVPN is the best alternative with a similarly rigorous privacy stance, an open-source client, and Secure Core routing. Both support WireGuard and OpenVPN with full Linux CLI tools.

Question 2

Does a VPN interfere with local development servers and APIs?

Accepted Answer

VPNs can interfere with local development if split tunnelling isn't configured correctly — traffic to localhost and LAN addresses should bypass the VPN tunnel. Mullvad, ProtonVPN, and NordVPN all support split tunnelling on Linux. Windscribe offers the most flexible port and protocol configuration for developers running services on non-standard ports. Always test VPN behaviour against your development stack before relying on it for production work.

Question 3

Which VPN has the best Linux support for developers?

Accepted Answer

Mullvad is the gold standard for Linux — it ships a polished GUI client for Linux alongside full CLI tools, supports WireGuard and OpenVPN, and provides detailed documentation for manual configuration. ProtonVPN's Linux client is also well-maintained with GUI and CLI support. NordVPN's Linux support is CLI-based and functional. Avoid VPNs whose Linux support amounts to a manual OpenVPN config file — they're difficult to maintain.

Question 4

Can I use a VPN to test geolocation features in my application?

Accepted Answer

Yes — this is one of the most useful developer applications of a VPN. By connecting to servers in specific countries, you can test how your application behaves for users in different regions, verify geo-restricted content delivery, and check localisation behaviour. NordVPN's wide country coverage (60+ countries) makes it particularly useful for geographic testing across markets your application targets.
