The toolbox
Two tools today. More on the way.
Each tool solves one real problem developers hit every week, runs entirely in your browser, and links its sources so you can check the math yourself.
Maps API cost calculator
Enter your monthly tile, geocoding, and routing volumes and see what Google Maps, Mapbox, MapTiler, Stadia, LocationIQ, Ola Maps, Mappls, and maps.guru would each charge. Pricing formulas mirror each vendor’s published rate card. 100% client-side, nothing leaves your browser.
8 providers · client-side · verified pricing →
Free GeoJSON viewer
Paste or drop a GeoJSON FeatureCollection and see it rendered on a real vector map. Validates the structure, reports geometry counts and bounds, and highlights broken features. No upload step, so your data never leaves the tab.

Store locator builder
Upload a CSV of store names, addresses and coordinates, preview them as clustered pins on a real vector basemap, and copy an embeddable store locator for WordPress, Shopify, React, Vue, or any HTML page. Everything runs in your browser.
