A vector map platform

Vector maps enable custom map appearance, language localization and label fonts.

  • Open data

    Protomaps is based on open data; you can combine the maps with other web services and overlays, and even improve the data yourself.

  • Universally compatible

    Uses the vector tiles standard, meaning you can use it with the simple Leaflet library and plugins, or other popular map renderers for the web and native apps.
