Jamstack
Jamstack is a modern web architecture that pre-renders pages at build time and serves them from a CDN, using JavaScript, APIs, and Markup to deliver fast, secure, and scalable websites.
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.
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.
In practice
- A media company migrated their WordPress blog to a Jamstack architecture (Next.js + headless CMS) and reduced page load times from 3.5 seconds to 0.8 seconds
- An e-commerce brand uses Jamstack for their storefront (Astro + Shopify API) serving 50,000 product pages from a CDN at near-zero hosting cost
- A documentation site for a developer tool moved to Jamstack and handles 10 million monthly page views on a $20/month hosting plan
- A marketing agency builds all client websites with Jamstack, reducing hosting costs by 80% and eliminating server maintenance entirely
