What is Hydra
Hydra is the custom technology that powers the Gamepedia wiki farm. Named for the legendary Greek monster, Hydra takes its name from the monster’s ability to grow many heads from a single body. In general terms, this enables us to power all of the wikis on Gamepedia from a single core installation of MediaWiki and makes it simple for us to manage MediaWiki updates and the addition of new features from a central location.
