WireGuard vs OpenVPN: Key Differences
By DexterVPN Editorial Team
WireGuard generally offers faster handshakes and lower overhead on many networks. OpenVPN provides UDP and TCP modes, making it a reliable fallback when UDP is blocked. DexterVPN plans to support both plus IKEv2 at launch on compatible platforms.
| Aspect | WireGuard | OpenVPN |
|---|---|---|
| Codebase size | Smaller, modern design | Larger, long deployment history |
| Transport | Primarily UDP | UDP or TCP |
| Typical use | Default fast option | Restrictive network fallback |
| Platform support | Wide on modern OS | Very broad including older devices |
Which should you try first?
Start with WireGuard for everyday use when available. If connections fail on hotel or corporate Wi-Fi, switch to OpenVPN TCP or IKEv2. Real-world speed still depends on server distance and network congestion.
Frequently asked questions
- Is WireGuard always faster?
- Often, but not guaranteed. Measure on your network rather than assuming marketing claims.
