Making Navigations Instant in v0

Last month we shared a preview of some new tools in Next.js 16.3 that bring instant page navigations to apps built with React Server Components.

We've been adopting these tools in v0 , Vercel's full-stack coding platform, and we shared this graph showing how much faster navigations got in production:

Impressively, these results came from a coding agent using a new Skill to write failing tests, fix the slow navigations, and verify each route.

We'll go over how those tests can assert against slow navigations and how the Skill works.

But first, let's look at the approach Next.js 16.3 takes to making apps like v0 feel snappy, without needing to move any data-fetching or rendering code to the client.
