# What is JAMstack?

JAMstack is a web architecture in which ready, static HTML files are served from a fast CDN while dynamic features come from APIs. The result: sites that are lightning-fast, secure and resilient under load.

The name comes from JavaScript, APIs and Markup. The idea: instead of assembling the page on a server at every visit (like classic WordPress), the site is built once – at publish time – and distributed as ready files to servers worldwide.

Practical benefits: **speed** (no server work per pageview), **security** (no database to attack at the front), **stability** (a traffic spike from a campaign doesn't kill the site) and **cost** (static hosting can be free).

This is the architecture we use for results-driven websites: content from a headless CMS, frontend in Astro/Next.js, forms and search via APIs.
