Top MediaWiki Extensions in 2022

Updated on November 12, 2022

There are thousands of extensions available for MediaWiki, so it can be tough to know which ones are the most useful. To help you out, we've compiled a list of the 10 most useful MediaWiki extensions.

The list of the best MediaWiki extensions of course depends on your use case. We thus focused on popular and often useful extensions.

What is a MediaWiki Extension?

Extensions add functionality to MediaWiki, or enhance existing features. They are written in PHP, and need to be added to the wiki by someone who has server access before they can be enabled. Other terms for MediaWiki extensions are MediaWiki plugins and MediaWiki addons, though the latter two are rarely used. They are comparable to WordPress plugins.

#15: Cite

The Cite extension allows adding footnotes from references, citations, and notes. The footnotes are created automatically at the bottom of pages. Cite is a feature-rich tool that empowers you to strengthen the credibility of the content, create context, and honor external material.

#14: Data Transfer

The Data Transfer extension is a practical tool to import data from CSV or spreadsheet files into your wiki. The import works by mapping the file content to templates and their parameters. Wiki pages are created automatically, and you can choose to do a full or partial import.

Data Transfer is an excellent tool for creating and updating structured data, so it works well together with Semantic MediaWiki.

#13: Maps

Maps is the MediaWiki extension to visualize and work with geographical information. You can embed beautiful dynamic maps using either Leaflet or Google Maps.

The maps are highly customizable. Specify markers, lines, and polygons to show. Or choose the map layers, clustering options or the map's dimensions. Dozens of options give you an immense amount of control over the look and feel of the map, and it's behavior.

Maps comes with a visual map editor and GeoJSON support. It also provides parser functions for geocoding, coordinate formatting, and geospatial operations. Last but not least, it integrates with Semantic MediaWiki, enabling you to build maps from queried data.
