3000

The Next.js CLI defaults to port 3000. Other development servers may use it too, but Node.js and React themselves do not impose a universal listener port.
A React application uses the development port configured by its build tool or framework.
Scope
Port associations on this page are community-database references (common usage), not a live measurement of any machine; confirm with the official documentation before deployment.
