SanityAgency for structured content
Headless CMS, studio customization and blazing-fast Next.js frontends – from content model to launch.
Sanity-CMS-Agentur – happycoding
We are a Berlin-based agency focused on headless architectures with Sanity as the content platform. Our goal: websites and web apps that load extremely fast, perform strongly in SEO, and scale intelligently. With the headless CMS Sanity, we combine a highly flexible, structured content backend with modern frontends (e.g. NextJS) – ideal for marketing websites, content hubs, and omnichannel platforms.
High performance is no coincidence. By decoupling frontend and backend, using API-first delivery and intelligent edge caching, we deliver content within milliseconds – even under heavy traffic. This reduces server load, stabilizes operations, and measurably improves Core Web Vitals. SEO and visibility first: clean markup, lightning-fast load times, and optimal indexing form the foundation for sustainable growth.
Flexibility and integrations are among our core strengths: We seamlessly connect Sanity with systems like Shopify (headless commerce) or other APIs and data sources to create content hubs that manage and distribute content efficiently across all channels. Our team of strategists, developers, and designers share a passion for clarity and technical excellence. Real-time workflow: Sanity offers a modern, fast editorial interface – changes become visible instantly, and multiple team members can collaborate in real time without delays or conflicts. With Sanity, we build digital products that shine today and remain strong tomorrow – scalable, secure, and adaptable.








































































Typical Sanity projects
Sanity fits when your editors maintain content once and publish it in several languages, across several channels or alongside a shop and ERP.
Headless commerce with Sanity
Your marketing team publishes guides, brand stories and campaign pages on its own, while the shop keeps handling cart and checkout. Content in Sanity references products in Shopify or Medusa instead of copying product data.
Website connected to ERP and PIM
Your website shows prices, variants and specs straight from your ERP or PIM, and nobody has to type them in a second time. Sanity only holds the editorial content, so every type of data has exactly one system in charge.
From WordPress to Sanity in stages
You leave plugin sprawl and update anxiety behind without betting everything on a single launch day. Content moves to Sanity step by step, with a parallel run and redirects that protect your search rankings.
Choosing a CMS: Sanity or Contentful?
You are picking a headless CMS and want to know costs, flexibility and vendor lock-in before you sign. We measure Sanity, Contentful and other candidates against your requirements, even if a different system wins in the end.
Multilingual B2B website
Customers in your export markets find your offering, references and contacts in their own language. Your team maintains every language version in the same Sanity Studio and checks each page in preview before it goes live.
Website, docs and blog from one CMS
Your team writes the website, product docs and blog in one place instead of juggling three tools and three logins. One shared content model in Sanity feeds all three, so a renamed product updates everywhere at once.

What is a headless CMS – and why Sanity?
Definition
- Headless CMS
- A headless CMS manages content as structured data and delivers it through an API to any frontend – website, app, or digital products. The presentation layer is freely selectable and can be swapped independently.
Sanity is a headless CMS that manages content as structured data and delivers it through an API to any frontend. We use Sanity when multilingual B2B content needs to reach multiple channels and editorial teams need live preview and collaborative workflows.
