WBStack was created and launched in 2019 on the wbstack.com domain by Addshore.
The current deployment of this platform is wikibase.cloud (opens new window) by Wikimedia Deutschland.
The project provides a shared platform for Wikibase and other relevant services such as a Query service, Quickstatements, and more.
Users of individual wikis need not manage the technology or perform upgrades; they are all handled centrally.
You can read the original announcement post here (opens new window) and can watch the original live demo here 📺 (opens new window).
The WBStack name lives on representing the technology and open source code bases that provide the wikibase.cloud service today.
