Sthan Io runs on your own machine — the client starts it, so there is no endpoint to ping. 35 installs a week from npm. Last commit 28 Jun 2026.
US address verification, parsing, autocomplete, geocoding, and IP geolocation APIs.
Today is the operative word: we check Sthan Io every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
