Mapbox allows users to pull from a dozen basemap designs ranging from terrain to more creative historical- and comic-themed designs. The Mapbox Studio design tool is open source and you can look at the map and the coding side-by-side so that you can see exactly how each of your coded changes look in real time.
Mapbox is free to use, but if you want a large number of map views, data storage, and custom styles, there are pay-for-use plans available for upgrading.
The Mapbox showcase highlights projects undertaken by organizations ranging from Pinterest to National Geographic to Etsy that rely on the Mapbox framework.
Guides are available to walk users through making a map with Mapbox Editor as well as more detailed guides on how the Mapbox framework operates.
