GridPin offline geocoder runs on your own machine — the client starts it, so there is no endpoint to ping. 322 installs a week from pypi. Last commit 15 Oct 2026.
Offline geocoding and reverse geocoding from one local file per country. No API key, no rate limit.
Today is the operative word: we check GridPin offline geocoder every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
