"The Rails Port"

Build Status Coverage Status

This is The Rails Port, the Ruby on Rails application that powers the OpenStreetMap website and API. The software is also known as "openstreetmap-website".

This repository consists of:

  • The web site, including user accounts, diary entries, user-to-user messaging
  • The XML-based editing API
  • The integrated versions of the Potlatch, Potlatch 2 and iD editors
  • The Browse pages - a web front-end to the OpenStreetMap data
  • The GPX uploads, browsing and API.

A fully-functional Rails Port installation depends on other services, including map tile servers and geocoding services, that are provided by other software. The default installation uses publicly-available services to help with development and testing.


This software is licensed under the GNU General Public License 2.0, a copy of which can be found in the LICENSE file.


The Rails Port is a Ruby on Rails application that uses PostgreSQL as its database, and has a large number of dependencies for installation. For full details please see
