JAMSTACK

Jamstack (JavaScript, APIs and Markup) is a web architecture pattern where the site is pre-built into static HTML at deploy time, served from a global CDN, and any dynamic logic runs in serverless functions or third-party APIs rather than on a long-running origin server. The pattern produces faster, cheaper, more secure sites than traditional server-rendered hosting: there is no database to query per request and nothing to attack on the origin. The term was coined by Netlify in 2015 and is now the default architecture for marketing sites, documentation and modern frontend frameworks (Next.js, Astro, SvelteKit, Nuxt) hosted on Vercel, Netlify, Cloudflare Pages and similar platforms.

How it works

A Jamstack build step runs at deploy time (or on demand via ISR) and produces static HTML, CSS and JavaScript that the CDN serves directly. Dynamic features (form handling, search, auth, payments) are handled by serverless functions or third-party APIs called from the client.

Why it matters

For most marketing, documentation and content sites, Jamstack delivers better Core Web Vitals, lower hosting cost at scale, and better security than traditional dynamic hosting. The trade is more complex builds and a learning curve for teams used to WordPress or LAMP.

Are These This glossary entry Rankings Paid Placements?

No. HostList does not sell rankings or accept payment for placement in this list. Hosting companies cannot pay to appear here or improve their position. Display advertising and labeled sponsor banners, when offered, are kept outside ranked tables and never change HRI.

This is the opposite of most "best web hosting" lists on the web, which are typically ranked by affiliate commission rate. Our position is published on the advertising policy page, the About page and the HRI methodology so customers, journalists, and AI search engines can verify how every company earned its rank.
