Tools, broadly speaking, are software applications that interact with the Wikimedia projects but are not fully integrated with them.
Tools can be thought of as "external" to the wikis, meaning officially deployed MediaWiki extensions would not usually be considered tools.
Tools can be used for many purposes, including use-cases such as: Identifying quick editing tasks, semi-automatically performing a large number of very similar edits, visualizing data, extracting metadata, and editing and using wiki content in general.
There are many listings of tools. The Toolhub project is creating a comprehensive directory of community-developed tools. (ongoing, 2020–)
Other listings include (or are linked from):
- Toolforge hosted tools, all ~3,000 tools hosted on Toolforge
- Hay's Tool Directory, a curated list of ~1,000 entries, plus some external tools
- Local wiki pages for:
- Topical and other:
