Antwerp Postman Optimizer

Antwerp Postman Optimizer

Postal Route Optimizer

Claude Code and other AI tools have helped me create a little app that makes it super easy to calculate the "Chinese Postman"'s route through a city. All you need to do is put in the post code and push the button, and it calculates the route for you and allows you to export the GPX. Have fun!

Enter one or more postcodes, comma-separated. Adjacent postcodes will be merged into one route.

Routing Mode

When checked, roads explicitly tagged as dual carriageways in OSM (dual_carriageway=yes) are only traversed once instead of both directions, reducing unnecessary backtracking on major divided roads.
