Updated evals: nextjs.org/evals
Set up guide: nextjs.org/docs/app/gu...

Next.js installs will soon include version-matched docs, giving agents context on new and recently updated APIs.

In our evals, this improved success rates by ~20%.

Building Next.js for an agentic future How we built and sunset an in-browser agent, shipped MCP integration, and learned that better AI agent support means thinking from the agent's perspective.

As more Next.js apps are built with AI, we've been focusing on improving the agent experience.

Here's what we've learned, and how we're thinking about agents as first-class users ↓

Guides: Public pages Learn how to build public, "static" pages that share data across users, such as landing pages, list pages (products, blogs, etc.), marketing and news sites.

Learn more about this pattern: nextjs.org/docs/app/gu...

Two ways to handle a blocking component in Next.js:

• Cache: so it can be prerendered with the rest of the page.
• Stream: so the rest of the page doesn't have to wait for it.

unstable_cache() was never stable, it was a temporary API added. There are many ways to do caching in your backend – you didn't explicitly have to use this.

"use cache" won't be ready for production until stable. It's regardless of the platform you deploy to. You can still use Redis or lru-caches.

Yes!

Our latest release was a minor (v15.2) – there are no breaking changes until v16. We are focused on performance improvements, stability, and soon a simplified caching model.
