We at StreetEasy decided to build our own maps using, among other tools, OpenStreetMap, TileMill, MapBox and Leaflet, instead of paying hundreds of thousands of dollars per year to Google. And yes, the money pushed us into doing it, but we’re happier with the result because we now control the contents of our maps.
The free ride had to end for most companies. But what is surprising is how easy it is to change your tile map service. Plus see a theme here? OpenStreetMap, TileMill, MapBox, and is a trend. Giddy up!
