Next.js Cache Strategies

Explore modern rendering patterns in Next.js, including PPR, Suspense, and various Cache Component methods. We've simulated a 4000ms API delay on every action.

Rendering Experiments Active

Blocking (No Fallback)

The slowest method. The entire page navigation is blocked while data fetches, resulting in a "stuck" feel.

Launch Demo

Standard Suspense

A step up. Navigates immediately but shows a full-page loading state while sequence awaits complete.

Launch Demo

PPR Stream

The gold standard. Static shell loads instantly, dynamic parts stream in parallel as they ready.

Launch Demo

Strategic Comparison

Method A

Feels "broken" as the browser wait cursor appears. No UI feedback during fetch.

Method B

Better feedback, but sequence awaits block the main thread, slowing down perceived speed.

Method C

Static shell is instant. Dynamic content fetches in parallel, keeping the UI alive.
