WireGuard vs OpenVPN

Both are VPN protocols that build an encrypted tunnel. The honest summary: for almost everyone, WireGuard is the better default in 2026. OpenVPN still has a few niche advantages. Here is the real comparison, not the marketing one.

Speed

WireGuard wins, usually by a wide margin. Its lean design and kernel integration mean less CPU per packet, higher throughput, and faster reconnects when you change networks. OpenVPN is heavier and shows it on mobile.

Code size and auditability

WireGuard is ~4,000 lines; OpenVPN is hundreds of thousands. Smaller code is easier to audit and has less room for vulnerabilities. This is the security argument that actually matters.

Cryptography

WireGuard uses one modern, fixed cipher suite — you can't misconfigure it into something weak. OpenVPN is flexible, which is powerful but also means a badly-configured OpenVPN can be insecure. Fixed-and-modern beats flexible-and-fragile for most people.

Where OpenVPN still wins

OpenVPN runs over TCP port 443, which lets it masquerade as ordinary HTTPS traffic. On heavily censored or restrictive networks that block everything unusual, that camouflage can get through where plain WireGuard won't. There are obfuscation layers for WireGuard too, but out of the box OpenVPN-over-443 is still the better evasion tool.

What vpn.golf uses

WireGuard, for the speed and the key model (your private key is generated on your device and never sent to us). For restrictive networks we plan obfuscation rather than falling back to OpenVPN.
