Protomaps is a free and open source map of the world, deployed as a single file you can host yourself. It enables interactive, zoomable mapping applications with only static storage and HTTP Range Requests. It uses the OpenStreetMap dataset as a primary source; its configurable toolchain can create maps with specific areas, custom data, and different cartographic styles. It’s used in earth science, journalism and the public sector. Protomaps has no vendor lock-in, permits end-to- end data sovereignty, and can ensure end-user privacy.
