WikiTeam software is a set of tools for archiving wikis. They work on MediaWiki wikis, but we want to expand to other wiki engines. As of 2020, WikiTeam has preserved more than 30,000 stand-alone wikis, several WikiFarms carrying hundreds of thousands of wikis, regular Wikipedia dumps and dozens of TB of Wikimedia Commons images.

There are thousands of wikis in the Internet. Everyday some of them are no longer publicly available and, due to lack of backups, lost forever. Millions of people download tons of media files (movies, music, books, etc) from the Internet, implementing a kind of distributed backup. Wikis, most of them under free licenses, disappear from time to time because nobody grabbed a copy of them. That is a shame that we would like to solve.

WikiTeam is the Archive Team subcommittee on wikis. It was founded and originally developed by Emilio J. Rodríguez-Posada, a Wikipedia veteran editor and amateur archivist. Many people have help sending suggestions, reporting bugs, writing documentation, providing help in the mailing list and making wiki backups. Thanks to all, especially to: Federico Leva, Alex Buie, Scott Boyd, Hydriz, Platonides, Ian !McEwen and Mike Dupont.
