What uMap is
uMap is a free, open-source mapping tool for creating maps with OpenStreetMap layers and embedding them in websites. Users can place markers, draw lines and polygons, select colors and icons, and configure options such as a minimap or user geolocation. Maps can be shared publicly, with anyone who has a link, or with editors only. Authors can choose a license for their map data and embed maps through an iframe. The homepage lists batch import for GeoJSON, GPX, KML, and OSM data. Documentation also covers importers for Overpass, datasets, OpenDataSoft, and several France-specific sources, depending on server configuration. With an API key, OpenRouteService can add route drawing, isochrone calculation, and line elevation features. uMap runs on the web or through self-hosting, with documented Docker, Dokku, and YunoHost deployments. Its software uses the AGPLv3 license. Map creation is offered on OpenStreetMap Germany, Switzerland, and France servers. Self-hosted installations require a unique secret SECRET_KEY.
Good
- Free and open source
- Markers, lines, and polygons
- Batch geographic-data imports
- Flexible sharing permissions
- Documented self-hosting options
Watch out
- Some importers depend on server configuration
- OpenRouteService needs an API key
- Self-hosting requires SECRET_KEY configuration
- Data refresh is manual
Who it suits
uMap suits people creating and embedding custom OpenStreetMap-based maps. It is also appropriate for users who want open-source software, self-hosting, configurable sharing, or imported geographic data.
Verdict
uMap offers open-source map creation with drawing tools, imports, embeds, sharing controls, and self-hosting options. Advanced integrations depend on configuration, and self-hosted deployments require careful secret-key setup.
