Create individual maps for your places, tracks and events, and share them in real time.

See the demo map here

Mapforge is an open source GIS web application. Create and share your places, tracks and events as GeoJSON layers on different base maps, with MapLibre GL JS on desktop and mobile. Changes are synced live to all clients.

Features

Map and data

• Create maps with your own data on top of various available base maps.
• 3D terrain, hillshade, contour lines and globe projection
• Draw shapes and style them: Add pictures, customize colors, symbols, labels, (3D) polygons, indoor maps and more. The style attributes extend the GeoJSON / Mapbox simplestyle spec.
• Import and export GeoJSON, GPX and KML
• Search places and addresses, including the features of the open map
• Integration with Overpass API for custom OpenStreetMap queries

Routing

• Plan routes for walking, bicycle and car with openrouteservice, with elevation profile and route color coding by steepness or surface

Collaboration and sharing

• Real-time collaborative editing, changes sync to every connected client over WebSockets
• Share maps and embed on your own web page

Apps and platforms

• Desktop and mobile UI
• PWA support by default, ships as an Android app via Bubblewrap
• Record GPS tracks with the built in µlogger API
• Login with Google, GitHub or OSM OAuth, no auth system to maintain

Privacy and self-hosting

• Self-host with ready-to-use Docker Compose file
• No ads and no tracking

Development

Mapforge is a Ruby on Rails 8 application. It uses Mongoid on MongoDB for persistence, Redis and Action Cable for live sync, and Importmap with Turbo and Stimulus for the frontend. The map uses MapLibre GL JS, mapbox-gl-draw for drawing and Turf.js for geometry calculations.
