Dynamic website
A website that generates or changes responses using application logic, stored data, user state, or external services.
Also called: dynamic site, web application
Definition
A dynamic website may run code for each request, read from a database, personalize output, accept authenticated actions, or obtain data through an API. Some modern sites combine prebuilt pages with dynamic functions.
Why it matters
Dynamic behavior can support useful workflows but adds runtime, security, testing, maintenance, and recovery responsibilities.
Common misunderstanding
A site can contain animations or client-side interaction and still be delivered mostly as static files.
