Core Content Projects
- There are Wikipedias (encyclopedias) in over 310 languages, some of which contain more than one million articles.
- There are Wiktionaries (dictionaries) in over 180 languages, some of which contain more than one million entries.
- There are Wikibooks projects (textbooks) in 120 languages, the largest of which contain more than 80,000 pages.
- There are Wikiquote projects (quotations) in over 90 languages, the largest of which contain more than 30,000 pages.
- There are Wikisource projects (source texts) in over 70 languages, the largest of which contain more than 600,000 pages. In addition, there is a multilingual "old" Wikisource wiki containing portals for languages that don't have their own separate domains yet (these are being migrated to the Incubator).
- There are Wikinews projects (news articles) in over 30 languages, the largest of which contain more than 50,000 articles.
- There are Wikiversity projects (educational materials) in more than 15 languages, the largest of which contain more than 40,000 pages.
- There are Wikivoyage projects (travel guides) in more than 20 languages, the largest of which contain more than 25,000 pages.
- There is one multilingual Wikimedia Commons project containing over 86 million files that can be used by all other Wikimedia projects.
- There is one multilingual (but mostly in English) Wikispecies project containing over 800,000 entries about living things.
- There is one multilingual Wikidata project containing over 100 million items that can be used by all Wikimedia projects in all languages.
The Incubator is a project that helps other projects get started while they are still building up a community. One wiki for all languages.
The original domain for Wikisource hosts three kinds of material: works that are multilingual or non-lingual (such as music scores), works that are in a language that has a very small body of literature, and works in languages that can be incubated to their own subdomains.
Wikiversity Beta is used to incubate new Wikiversities.
Organizational and Planning Projects
This is a multilingual project for meta-discussion about all issues related to Wikimedia as a whole, and as well as for any cross-project collaboration. For more information see Meta:About.

These kinds of things should *not* go here or on any wiki for that matter:
- Accounts and passwords
- Private Donor information, especially anything that would make an "anonymous" donor identifiable
- User's personally identifiable information
- boardwiki – for the Board of Directors and Executive Director
- collabwiki – for private workspace for collaboration between Wikimedia staff and external contractors; as of 2014, used e.g. for fundraising translations
- The fundraising systems are naturally sensitive, and thus are documented on CollabWiki to restrict access to that information.
- Also used for random non-public information shared between fundraising team members (and others?) which doesn't need to be kept secret from officewiki users.
- officewiki – for Wikimedia staff-only documentation (eg. HR, Office IT and other internal procedures)
- The Office IT systems are for staff use only and are documented on OfficeWiki to limit information about sensitive staff-only resources.
- Note: some contacts info are on CiviCRM instead (or many other places): http://contacts.wikimedia.org

- Subdomains of Main Domains
- Beta Cluster (runs in Wikimedia Cloud VPS)
- Main page: https://beta.wmflabs.org/
- Test wikis that run with URLs like https://en.wikipedia.beta.wmflabs.org, https://simple.wikipedia.beta.wmflabs.org, https://meta.wikimedia.beta.wmflabs.org, etc.
- Subdomains not following any clear rule like http://education.wmflabs.org
- wmflabs.org wikis are not meant to host any original content (discussion, reports or whatever) but should only be considered as short-lived sandboxes. However, most of them don't give this very valuable information to most users.
|Name||Version of MediaWiki||Description||URL||Status|
|Test Wikipedia||Current Wikimedia production version||Hosted within the production cluster, runs the current Wikimedia production branch of MediaWiki. It is most useful for various tests of features before even applying them on other production wikis, like scripts or in upon testing other features.||test.wikipedia.org||Open|
|Test2||Current Wikimedia Production Version||Matches test.wikipedia.org.||test2.wikipedia.org||Open|
|Beta Cluster||Latest Master From Git||Isolated clone of the production cluster, deployed directly from git. May be unstable. Users can test gadgets and scripts for compatibility with future releases. Wikis here are not accessible from anywhere, nor explained clearly, nor have an index or any navigation tool.||beta.wmflabs.org||Open|
Most analysis is focused on publicly-editable wikis (unlike, for example, Office Wiki, accessible only to Wikimedia Foundation staff), not meant for software testing (e.g. Test Wikidata), and not temporary (e.g. Wikimania 2016).
On the Toolforge replica, use the "meta" database to find information about Wikimedia wikis and their databases. This example returns wikis, which are active now:
select dbname as db_name, family as project, lang as language, url as domain from wiki where is_closed = 0
Query for getting a list of public wikis (tailored to some database accessible to researchers):
select site_global_key as db_name, site_group as project, site_language as language, concat("https://", trim(leading "." from reverse(site_domain))) as domain from enwiki.sites where site_group in ( 'betawikiversity', 'commons', 'incubator', 'labs', 'mediawiki', 'meta', 'outreach', 'sources', 'species', 'wikibooks', 'wikidata', 'wikinews', 'wikipedia', 'wikiquote', 'wikisource', 'wikiversity', 'wikivoyage', 'wiktionary' )
Some wikis (both public and private) are closed to any further editing. The canonical list is at https://noc.wikimedia.org/conf/dblists/closed.dblist.
These are wikis that display content meant for the general public rather than specifically for the Wikimedia community (analogous to content namespaces).
These are wikis in the following site groups:
( 'betawikiversity', 'commons', 'incubator', 'sources', 'species', 'wikibooks', 'wikidata', 'wikinews', 'wikipedia', 'wikiquote', 'wikisource', 'wikiversity', 'wikivoyage', 'wiktionary' )
These are certain projects that are not officially hosted on the Wikimedia server farm, but are also most practically used though by the projects.
Translatewiki.net is a project that is used to translate many of the more effective strings for some of the Common Gateway Interfaces and other creative tools that the Wikimedia sites use.
- List of canonical domain names owned by the Wikimedia Foundation, including some non-wikis ("While the Foundation may own many other domains for trademark, legal, or project/redirect reasons, there is only one small set which are considered to be the canonical set for our actual projects and content, which are subjected to higher standards.")
- OpenStreetMap (OSM) is a collaborative project which is similar to a wiki in that people around the world contribute geographic data that can be used for many aspects related to mapping. Integration between OSM and WMF projects is close and much of their data can be reused within Wikimedia projects. See more details at mw:Maps.
