Fellow mappers,

I have the pleasure to announce the initial release of a high-perfomance
routing backend that is able to handle thousand(s) of requests per
minute. So, without further ado, here is the Open Source Routing Machine
(OSRM), an engine that lets you serve shortest paths within miliseconds
or even less. Some of the highlights:

 - blazingly fast shortest path computation
 - standardized KML output of the routes
 - tools to preprocess and to serve the routes of any .osm file
 - multicore support
 - open source
 - actively under development

Give it a try by pointing your browser to


where a demo installation with a nice and light web user interface
serves routes for the road network of Western Europe. Thanks to Frederik
and Jochen at Geofabrik for serving and preparing the demo.

The source of the routing engine is freely available under the Affero
GNU Public License (AGPL) at


for anyone.

This first release gives you fast routes and there are many things that
are going to follow in the coming months, i.e. turn directions have not
yet been implemented and does not obey turn restrictions. Also, the
extraction of the road network is still rudimentary. Questions, bug
reports and patches are welcome, be it on this list or at the projects
bug tracker [1].

Best wishes and happy routing,
