WireGuard vs OpenVPN: which one should you use?

WireGuard and OpenVPN both encrypt all traffic between your device and the VPN server. They differ in how they are built, how you set them up and how well they get through restrictive networks.

Speed and battery

WireGuard is a much smaller, newer protocol with modern cryptography. In practice it usually connects faster, reconnects quickly when you switch between Wi-Fi and mobile data, and uses less battery on phones. OpenVPN is older and heavier, but still fast enough for browsing and video on most connections.

Setup

• WireGuard: import one small configuration file or scan a QR code. There is no username or password to type.
• OpenVPN: import a profile file (.ovpn), then sign in with the username and password shown on your configuration page.

Getting through restrictive networks

Both protocols on this site use UDP. Some hotel, office or school networks block unusual UDP traffic. If neither connects, try V2Ray, which runs over normal HTTPS on port 443, or an SSH tunnel in TLS or WebSocket mode.

Which one to choose

• On a phone or laptop on a normal network: WireGuard.
• If your app or router only supports OpenVPN profiles: OpenVPN.
• If both are blocked: V2Ray.
