Overview
FocusReactive is a Next.js development company and headless CMS agency specialising in high-performance websites, composable content systems, and CMS migrations. As an official partner of Sanity, Storyblok, Contentful, and Payload CMS, we build vendor-agnostic architectures across the modern Jamstack ecosystem — Next.js, Gatsby, Nuxt, Qwik, and Astro. Performance and AI SEO aren't services we bolt on — they're built into every project through Core Web Vitals optimisation, render strategy, and structured data from day one. Headquartered in London with an office in Warsaw, FocusReactive works with clients across the UK, Europe, and beyond who have outgrown their current stack and need a migration or new build done without SEO loss, technical debt, or editorial disruption
