Wire-Seek, a WireGuard MTU finder
Claude helped build a tool that finds the best MTU for WireGuard tunnels by binary-searching with ICMP path MTU discovery, then subtracting protocol overhead.

The full story
Finding the right MTU for a WireGuard tunnel usually means testing values one by one, and getting it wrong causes fragmentation or wasted overhead. Working with Claude, a developer built Wire-Seek, which uses ICMP path MTU discovery with a binary search to find the best value in about eight probes rather than 200 or more.
It then subtracts WireGuard's overhead (60 bytes for IPv4, 80 for IPv6). The tool went from idea to working version in one session, and the maker says Claude was especially helpful with the low-level networking details and suggested the binary search.
