Headless Wordpress Agency – happycoding

We are a Berlin-based agency with a clear focus on headless architectures using WordPress as the CMS backend. Our goal: websites and web apps that load extremely fast, perform strongly in SEO, and scale intelligently. With WordPress Headless, we combine the familiar editorial comfort of WordPress with modern frontends like NextJS — ideal for marketing websites, content hubs, and complex platforms.

Strong performance is no coincidence. By decoupling frontend and backend, using API delivery (REST / WPGraphQL), and leveraging edge caching, we deliver content in milliseconds — even under heavy traffic. This reduces server load, stabilizes operations, and measurably improves Core Web Vitals. SEO and visibility come first: clean markup, fast load times, and optimal indexing form the foundation for sustainable growth.

Flexibility and integrations are among our key strengths: we connect WordPress Headless with systems like Sanity, WooCommerce (Headless), Shopify, MedusaJS, or Strapi, integrate APIs and data sources, and create platforms that efficiently manage and distribute content across channels. Our team of strategists, developers, and designers shares a passion for clear structures and technical excellence. With WordPress Headless, we build digital products that shine today and remain just as strong tomorrow — scalable, secure, and adaptable.

Take your website to the next level with Headless WordPress — for more leads, higher revenue, and sustainable growth.

Through improved user experience (UX), optimized performance, and a scalable architecture, our headless relaunches help attract more visitors, convert leads, and drive sustainable growth.

Blazing-fast websites with Headless WordPress

WordPress Headless + NextJS frontends deliver enterprise-level performance. Decoupling, intelligent caching (Edge/CDN), modern frontend rendering (SSR/SSG/ISR), and structured content from the backend enable load times in milliseconds — even under heavy traffic. The result: better SEO, higher conversion rates, and a noticeably smoother user experience.
