It didn’t make a big splash, but Apple unveiled a new mapping tool last year at WWDC. MapKit JS is a JavaScript library that anyone can use to put Apple Maps on the web. It’s currently still in beta, but can be used by any registered Apple developer (with a daily limit on how many map views can be called).
Today, privacy-minded search engine DuckDuckGo announced that it will use the new MapKit JS tool for all its location-based search results. Previously, the site used OpenStreetMap for its results, with a drop-down box kicking you off to Bing, Google, or Here maps if you asked for directions.
