Protocol Details

WireGuard

Modern, fast, efficient. ~4,000 lines of code (vs 100,000 for OpenVPN). Best performance on mobile. Default choice for most users.

OpenVPN

Battle-tested, highly configurable. TCP mode works on port 443 to bypass firewalls. UDP is faster but blocked more easily.

IKEv2

Excellent for mobile—reconnects instantly when switching between WiFi and cellular. Built into iOS and Android.

PPTP (Avoid)

Broken encryption. Only use if you need speed and don't care about security at all. Not recommended.
