## What it is
Mapus is an open-source web application for exploring and annotating maps with real-time collaboration, built on Leaflet and Firebase. Users can draw, add markers, lines, and areas, search places, and observe other users, similar to Google MyMaps with multiplayer support.

## Use cases
- plan a trip with friends on a shared map in real time
- annotate a map with markers, lines, and areas
- collaboratively draw routes and measure distances
- find places and things to do nearby
- export map annotations as GeoJSON
- self-host an alternative to Google MyMaps

## When to choose
- you need real-time multiplayer map annotation
- you want a free, self-hosted Google MyMaps alternative
- you want to export collaborative map data as GeoJSON

## When to avoid
- you need a production-ready hosted service without setup
- you don't want to configure your own Firebase project
- you need advanced GIS analysis rather than annotation

## Facets
