Geo Hound

Geo Hound automatically detects and saves GIS services as you browse — WMS, WMTS, WFS, ESRI FeatureServer/MapServer, OGC API Features, tile services, and downloadable geospatial files. Found a useful service? It's already in your dashboard. Built for GIS analysts, researchers, and developers who waste hours hunting through network panels and copying URLs by hand. 🔥 New in v2.0: The Workbench + AI Assistant A full map workspace, free, built right into the extension - Add any detected service straight onto an interactive map with a basemap switcher, legend, and feature labels - Attribute table dock with sorting, an AND/OR filter builder, column stats, CSV export, and row-to-map highlighting - Analysis tools: buffers, select by attribute, select by location, spatial join, nearest-distance, symbolize by attribute, and a field calculator - Import your own data — GeoJSON, KML, KMZ, GPX, shapefile, XLSX - Export to GeoJSON, KML, XLSX, shapefile, CSV, a PNG map image, or a full PDF map report - Draw point, line, and polygon annotations with labels and colors, plus measurements - Sessions auto-save and restore — close the tab and pick up right where you left off - Light and dark themes Chat with your layers using the AI assistant (paid, prepaid credits — no subscription, with free monthly questions to try it) - Ask in plain English: "buffer the schools by 500m and show which parcels intersect" - The assistant searches your detected-services catalog, adds layers, runs multi-step analysis chains, styles results, and exports them - Works against your current map view as the area of interest, and is upfront about it — clear PARTIAL vs ALL DATA badges tell you when a number only covers what's loaded - Guardrails stop you from accidentally loading unworkably huge datasets - Your raw data never leaves the browser — the assistant only ever sees schemas, counts, and small samples - Credits are a one-time purchase that never expires; team credit pools are available for organizations Still the core hunting and validating you rely on - Auto-discovers sibling layers, reads live Leaflet/MapLibre maps, consolidates sharded tile CDNs, and de-duplicates tile floods - Full HTML descriptions, keywords, layer lists, formats, CRS, and bounding boxes pulled automatically - One-click CORS testing tells you what actually works in Leaflet or OpenLayers, with "Fully Compatible," "Web Map Compatible," or "Disabled" badges - A community directory shows which services other users found on the same site — your tile services and credential-bearing URLs are never shared - Folders, notes, search, and JSON export for team sharing With Geo Hound, you can: ✅ Detect services automatically as you browse ✅ Build maps, run spatial analysis, and manage attribute data in the free Workbench ✅ Chat with your layers using the AI assistant on prepaid credits ✅ Download features and imagery to GeoJSON, PNG, JPEG, or GeoTIFF ✅ Test web compatibility with one-click CORS validation ✅ Import GeoJSON, KML, KMZ, GPX, shapefile, and XLSX — export data, CSV, and PDF map reports ✅ Organize services with custom folders and notes ✅ Disable detection on selected URLs or domains Perfect for: - GIS analysts building web mapping applications - Researchers gathering geospatial data sources - Developers integrating mapping services - Data scientists working with spatial APIs Stop manually copying GIS service URLs, testing CORS compatibility, or digging through network requests. Let Geo Hound hunt down, map, analyze, and download geospatial data for you — saving hours of tedious work on every project. Guides and updates: geohound.app
