You may now start to see Apple Maps embeds in websites around the internet, as Apple has opened up a web-based API for developers in beta, it announced today at WWDC.

In the past, Apple has embedded maps on some of its websites like iCloud.com’s Find My iPhone page or the Apple Store site. But the company has kept the ability to embed Apple Maps on web browsers internal until now, unlike its rivals, Google Maps and Microsoft’s Bing Maps.
