The LocalWiki software is written in a combination of Django and custom Python code. In addition, it relies on PostGIS for mapping functions, the Apache Solr search engine, and the Jetty web server (which is a dependency of Solr). The package is pre-built for Ubuntu, and the project strongly encourages using Ubuntu as the deployment platform, but there are installation instructions for other OSes as well. By default, the wiki uses the CloudMade map server, which requires a free API key, but this is configurable.
