Tailscale Deep Dive: Why Developers Are Ditching Traditional VPNs

Tailscale is built on WireGuard and adds three critical layers—a coordination server for key distribution, NAT traversal via STUN, and a mesh network architecture—eliminating the complexity of traditional VPN setup. WireGuard's fixed cryptography and minimal codebase deliver 3-4x the throughput of OpenVPN with sub-100ms connections. Unlike traditional VPNs that route all traffic through a central server, Tailscale creates direct encrypted peer-to-peer tunnels, with the coordination server only distributing public keys and endpoints.
