Routing around Google Maps in Korea: Naver & Kakao deep links, weird coordinates, and iOS clipboard

Short summary

Google Maps doesn't work in Korea—this post walks through K-Map Router, a tool converting Google Maps links to Naver/Kakao deeplinks. It tackles non-obvious problems: protobuf-encoded geocodes, reversed lat/lng in direction URLs, iOS clipboard permissions, and platform-specific schemes. Built with Claude Code; stateless Cloudflare Worker + React, open-sourced on GitHub.

• •K-Map Router converts Google Maps URLs to Korean map app deeplinks (Naver, Kakao)
• •Solves coordinate format quirks: protobuf-encoded geocodes, reversed lat/lng pairs, multiple coordinate systems
• •Handles iOS clipboard permissions and platform-specific URL schemes; stateless Cloudflare Worker implementation
