Thottbot is an unofficial World of Warcraft plug-in and database website. The plug-in, which is programmed in Lua, collects information while a person is playing the game — such as the drop rates of items, locations of specific mobs, and quest information — and users then upload the information to the website's database. The information on the website only comes from players using the plug-in and who take the time to upload the data. Simon Carless of Gamasutra described Thottbot as a "major item listing site." As of March 9, 2008, web traffic company Alexa reported that Thottbot.com was the 250th most visited site on the internet.
Information contained on Thottbot includes descriptions of items, weapons and armor pieces. Web users can browse by categories or search by item names. Players may also create a profile of their current status, so that others may search and view different players. This also entails the user running a plug-in, and since it is a volunteer type of system, not every player is represented, nor is it guaranteed to be wholly up to date.
During the Austin Game Conference in 2006, World of Warcraft lead designer Rob Pardo spoke of the hardcore market and casual market for World of Warcraft, saying "The people that don't go to ThottBot are the casual players, and they're the ones you need to hold the hand of." A January 2007 article in the Detroit Free Press named the site as a good place to find jewelcrafting designs discovered during the beta test of World of Warcraft: The Burning Crusade.
