Welcome to Huggle! We hope you enjoy using our software.

What is Huggle?
Huggle is a fast diff browser application intended for dealing with vandalism or other unconstructive edits on Wikimedia projects, written in C++. It was originally developed in .NET by Gurch, who is no longer active on this project. Anyone can download Huggle, but rollback permission is required to use it in unrestricted mode on English Wikipedia.

Huggle is able to load and review edits made to Wikipedia in real time, helps users identify unconstructive edits, and allows them to be reverted quickly. Various mechanisms are used to draw conclusions to whether an edit is constructive or not. It uses a semi-distributed model where edits are retrieved using a "provider" (this can be anything that is capable of distributing a stream of edit information, such as the Wikipedia API or IRC recent changes feed), pre-parsed and analyzed. This information is then shared with other anti-vandalism tools, such as ClueBot NG. Huggle also uses a number of self-learning mechanisms, including a global white-list (users that are considered trusted) and user-badness scores that are stored locally on the client's computer.

How does it work?
Huggle is connected to mediawiki through API and retrieves a list of edits that are made to a wiki in real time. These edits are then evaluated and moved to queue from which user can open them. If edit contains some problems, it can be easily reverted, usually by a shortcut such as Q (by default this revert and warn the user who made the edit).

What are the system requirements for using Huggle?
Huggle 3 supports OSX, Linux and Windows directly. Huggle 2 only works on Windows XP, Windows Vista, and Windows 7, but there is also conditional support available for Huggle 2 via Wine on OS X and Linux (more information).
