GeoHound – Find The GIS Data Behind Any Web Map

Ever looked at a web map and wondered where the data lives? GeoHound is a Chrome extension that detects the services behind any web map as you browse – WMS, WFS, OGC APIs, ArcGIS REST, tile services, GeoJSON, 29 types in all – and saves them with their metadata.

A built-in workbench then lets you filter, buffer, join, and export that data right in the browser: no DevTools spelunking, no desktop GIS. The detector and workbench are free, and an AI assistant can run GIS tasks on your saved layers in plain English.
