What is a JAMstack?

With JAMstack (Javascript, API and Markup stack), the entire front-end of a website (i.e., the client-side) is built into optimized static pages and assets during the website, web application, and form build process. This JAMstack process includes pre-rendering results in sites to reduce the cost, complexity, and risk of dynamic servers as critical infrastructure. JAMstack websites allow the application logic to reside on the client side without being coupled to the back end server.
