🇬🇧 UK💷 GBP📊 Comparison🔒 UK GDPR⚖️ UK Law

Contentful is right for UK enterprise with large content teams and complex content governance requirements (content approval workflows, locale management, compliance-friendly audit logs). Sanity is right for developers who want maximum customisation and real-time collaborative editing (GROQ query language is genuinely powerful). Strapi is right for UK SMBs who want self-hosted, open-source headless CMS with full data ownership (UK GDPR data residency — Strapi on your own AWS eu-west-2). Strapi is ClickMasters' default for projects where UK GDPR data residency of content is required. Headless CMS choice affects UK GDPR compliance (where is content data stored?), content team workflow, and total cost of ownership.
