## What it is
uMap is a free, open-source web application for quickly creating custom maps with OpenStreetMap layers and embedding them in websites. It is built on Django and Leaflet, supports importing data layers (GeoJSON, GPX), and offers real-time collaborative editing.

## Use cases
- create interactive maps with openstreetmap layers without coding
- embed a custom map in my website
- import geo or gpx data onto a map
- collaboratively edit maps with a team
- self-host an online map creation tool
- draw lines and polygons on a map
- visualize public transport or point-of-interest data on a map

## When to choose
- you need quick, no-code creation of shareable, embeddable OpenStreetMap-based maps
- you want a self-hosted alternative to Google My Maps
- you need collaborative map editing and data layer imports like GeoJSON or GPX

## When to avoid
- you need advanced GIS analysis or desktop-grade cartography tools
- you only need a static map image or a lightweight client-side mapping library
- you require offline map rendering
