Was ist Jamstack?

Jamstack (originally JAMstack — JavaScript, APIs, Markup) represents a shift from traditional server-rendered web architecture. Instead of generating pages on-the-fly from a database for every visitor, Jamstack sites pre-build pages into static HTML at deploy time, serve them from a global CDN, and use JavaScript and APIs for any dynamic functionality.

The architecture typically involves a static site generator or framework (Next.js, Gatsby, Astro, Hugo) that builds HTML pages from templates and content sources, a headless CMS or API for content management, and a CDN for global distribution. Dynamic features like forms, search, comments, and authentication are handled through APIs and serverless functions.

The performance benefits are substantial. Pre-built static pages served from a CDN edge location load incredibly fast because there's no server processing, no database queries, and no waiting for page generation. This also makes Jamstack sites inherently more secure — with no server or database directly exposed, the attack surface is minimal.

Jamstack is ideal for content-heavy sites, marketing websites, documentation, blogs, and e-commerce storefronts. It's less suited for highly dynamic applications where every page is unique to each user (like social media feeds or real-time dashboards).
