description JAMstack Overview

JAMstack is a modern web development architecture built on three core components: client-side JavaScript, reusable APIs, and prebuilt Markup. The term was coined around 2015 by Mathias Biilmann, co-founder of the web hosting company Netlify, to describe an approach that relies on static site generators to pre-render files and serve them via a content delivery network. This architecture eliminates the need for a traditional web server, improving site speed, security, and scalability. It is utilized by frontend developers to create fast, highly decoupled web applications.

help JAMstack FAQ

What does JAMstack stand for?

JAM stands for JavaScript, APIs, and Markup, meaning prebuilt pages enhanced with browser JavaScript and external services. Netlify says Mathias Biilmann coined the term around 2015 to describe this decoupled approach. [Netlify](https://www.netlify.com/press/modern-websites-are-built-on-the-jamstack-architecture-due-to-performance-reliability-and-speed-of-developer-workflows-according-to-industry-survey-by-netlify/)

Does JAMstack mean a website cannot have a backend?

No, it means the presentation layer is separated from backend logic and data services. Forms, payments, search, and accounts can still use APIs, serverless functions, or separate application servers.

Where can a JAMstack website be hosted?

A JAMstack site can be deployed to Netlify, Vercel, Cloudflare Pages, Amazon S3, or another static host. The architecture is not tied to one company because the main output is normally HTML, CSS, JavaScript, and assets.

Why does JAMstack use prebuilt markup?

Pages are generated during a build and can then be served from a CDN without rendering every page on each request. Dynamic behavior is added with client-side JavaScript and APIs, which is the central idea described by Jamstack.org. [Jamstack.org](https://jamstack.org/)
