The DPjudge is the adjudicator arm of The Diplomatic Pouch, the homepage of the worldwide Diplomacy gameplay hobby since 1995. Using the DPjudge, players compete against one another in named Diplomacy games via a Web and email interface. The DPjudge supports a large number of variant maps and rules.

The project consists of Python-language source code, installation instructions allowing for multiple DPjudge instances on a single machine, HTML template and documentation Webpages, images, and map-generation files.
