CoMaps – community-led offline maps and navigation

CoMaps is a community-led maps and navigation application built around OpenStreetMap data. It focuses on offline use, privacy and community governance, with downloadable maps intended for driving, cycling, walking and outdoor navigation.

The project is derived from Organic Maps and Maps.Me, but follows its own development path. Maps remain usable without an active internet connection, and map data can be updated independently from the application itself so users can receive fresher geographic information without waiting for a full software update.

This is free and open source software.

Key Features

  • Provides downloadable OpenStreetMap-based maps for offline browsing, search and navigation.
  • Offers route planning and voice-guided navigation for driving, walking and cycling.
  • Provides turn-by-turn route previews while planning a journey before navigation starts.
  • Includes improved navigation guidance for roundabouts, U-turns, highway exits and road shields.
  • Supports lane guidance on supported platforms and keeps routing options separate for different transport modes.
  • Searches offline by name, address and point-of-interest category.
  • Shows hiking trails, cycleways, campsites, water sources, peaks, contour lines and other outdoor-oriented details.
  • Includes public transport and subway information where that data is present in OpenStreetMap.
  • Supports favourites, including searching and sorting saved places.
  • Records tracks and imports or exports bookmarks and tracks in KML, KMZ and GPX formats.
  • Includes a built-in editor for making selected improvements to OpenStreetMap data.
  • Allows map data to be refreshed separately from the installed application.
  • Runs on Linux as well as Android, iOS and macOS.
