Headless CMS
In short Headless CMS platforms store and deliver structured content via API, decoupled from any specific frontend. For EU buyers, the deciding question is where content and editorial-session data are stored and whether the vendor is EU-owned. Strong EU options on EU Vetted include Hygraph (Germany, EU-owned, the lowest CLOUD Act flag in the category, though it publishes no DPA and names no hosting region), DatoCMS (Italy, EU-owned, core content store on AWS in Ireland), and Prismic (France, EU-owned, though its own DPA places its data centres in the United States).

About Headless CMS
Headless CMS platforms decouple content storage from content presentation. Rather than rendering pages directly, they store structured content (articles, product data, landing pages, configuration blocks) and expose it via a content API (typically REST or GraphQL) that any frontend can consume: a Next.js website, a mobile app, a voice interface, or multiple channels in parallel. This architecture gives development teams full control over the frontend stack while allowing editorial teams to manage content through a structured authoring interface.
A headless CMS processes two distinct categories of data worth assessing on their own terms. Content comes first: product descriptions, marketing copy, and editorial data that may or may not be personal data depending on your use case. Operational data is the second category: editor accounts, IP addresses from API consumers, and draft content. Both categories are processed by the CMS vendor on managed plans. If the CMS vendor is US-incorporated or ultimately US-owned, the CLOUD Act can in principle reach this data. Hygraph (Germany) is EU-incorporated and carries the lowest CLOUD Act flag in the current catalogue (CLOUD Act exposure: Minor), but it publishes no DPA, no sub-processor list and no hosting region, so that flag rests on what the vendor has not disclosed. Prismic (France) and DatoCMS (Italy) are also EU-owned, but Prismic's own DPA states that the AWS infrastructure behind the Prismic Solution sits in the United States, and DatoCMS keeps its core content store on AWS in Ireland with customer-uploaded assets at rest on Cloudflare R2. Storyblok (Austria) and Strapi (France) are listed with EU-headquartered but US-funded ownership signals; Strapi is additionally available as a self-hosted open-source option that removes the vendor from the data-processing chain entirely.
