Next.js 15 stopped caching fetch by default, so requests are no-store unless you opt in

In the App Router of Next.js 13 and 14, fetch defaulted to force-cache and results were kept in the Data Cache indefinitely. Next.js 15 (October 2024) flipped the default to no-store. GET Route Handlers are no longer cached by default either, and the client router cache no longer reuses page segments.

Opt back in per call by setting cache to force-cache, per segment with export const fetchCache = 'default-cache', or for a Route Handler with export const dynamic = 'force-static'. Time based revalidation through the next.revalidate option still implies caching.

Confirm what actually happened by reading the route table printed at the end of next build, which marks each route as prerendered or server rendered. Development mode does not use the Full Route Cache, so caching behaviour must be checked against next build and next start, never against next dev.
