Headless CMS
Headless CMS platforms store and deliver structured content via API, decoupled from any specific frontend. For EU buyers, the key criterion is where content and editorial-session data are stored and whether the vendor is EU-owned. Top-rated EU options on EU Vetted include Hygraph (Germany, 4/5), Prismic (France, 3/5), and DatoCMS (Italy, 3/5).
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.
For EU buyers, a headless CMS processes two distinct categories of data that are worth assessing separately. The first is the content itself: product descriptions, marketing copy, and editorial data that may or may not be personal data depending on your use case. The second is operational data: 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, 4/5) is the highest-scoring EU-owned option in the current catalogue. Prismic (France, 3/5) and DatoCMS (Italy, 3/5) are also EU-owned. Storyblok (Austria, 3/5) and Strapi (France, 3/5) 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.
The listings below show each product's country of incorporation, ownership signal, and editorial compliance score on a 1–5 scale — sourced from published DPAs and corporate filings. Use the ownership filter if your procurement rules require strictly EU-owned processors, or the hosting filter to separate self-hostable options from cloud-only platforms. The features filter distinguishes CMS-only tools from those with built-in digital asset management, visual editing, or enterprise workflow capabilities.
