What Jamstack means
Jamstack decouples the front end of a site from the systems behind it. Pages are built ahead of time and served as static files, while anything dynamic is handled through APIs called from the browser or at build time.
The name nods to JavaScript, APIs, and markup, but the core idea is simpler: precompute what you can, and only reach out to a server for the parts that genuinely need it.
Why it performs
Because pages are prebuilt and served from a network close to the visitor, they load fast without waiting on a database. That directly supports strong page speed, which visitors feel immediately.
There is also less to attack and less to break. With no live server rendering each request, the surface for security issues shrinks and uptime tends to be excellent.
How the pieces fit
A Jamstack site is usually produced by a static site generator, with content managed in a headless CMS and dynamic features added through API integrations.
This is the model behind our performance work: fast, structured sites that are cheap to host and hard to knock over, without giving up the ability to edit content easily.
