Mapzen was an open-source mapping platform that provided tools and services for developers to build customized maps and geolocation capabilities into their applications. Founded in 2013, Mapzen offered various open-source projects including vector tile service, geocoding, and routing tools. The platform emphasized the use of open data and open-source projects to foster innovation in the mapping and geospatial industries. As of early 2018, Mapzen ceased its hosted services, but many of its open-source projects continue to be maintained by community contributors.
