Hygraph, formerly GraphCMS, is a headless content management system built around GraphQL. It stores structured content and delivers it through a single API to websites, apps and other channels. With content federation, Hygraph unifies content from separate sources, such as legacy CMSs, PIM, DAM and SaaS tools, into one content API, which removes the need for custom middleware. The product is aimed at development teams and organisations that publish across several channels, and it is delivered as SaaS.
Hygraph is headquartered in Berlin, Germany, and was renamed from GraphCMS in 2022. When you create a project you choose a hosting region; according to Hygraph these include an EU region as well as regions in the US and Asia-Pacific, so choose a European region deliberately if data must stay in the EU. For federated sources, those sources determine where the data resides. The software is not open source and cannot be self-hosted.
