We've spent the past year making Next.js work better with AI coding agents. From an experimental in-browser agent to MCP integration and improved logging, we learned that the key is treating agents as first-class users and giving them visibility into what Next.js is doing.

How we built Turbopack with incremental computation to scale development and builds to massive Next.js applications.

Next.js 16.1 is now available. Highlights include:

• Turbopack File System Caching for next dev (stable)
• Next.js Bundle Analyzer (experimental)

Two additional vulnerabilities have been identified in React Server Components: a high-severity Denial of Service (CVE-2025-55184) and a medium-severity Source Code Exposure (CVE-2025-55183). All Next.js 13.x, 14.x, 15.x and 16.x users should upgrade immediately.

A critical vulnerability (CVSS 10.0) has been identified in the React Server Components protocol that can allow remote code execution. All Next.js 15.x and 16.x users should upgrade immediately.

Next.js 16 is now available with major improvements to developer experience, routing, and caching. Highlights include:

• Cache Components: A new programming model leveraging Partial Pre-Rendering (PPR) and use cache for instant navigation.

• Turbopack for builds (alpha)
• Community support for Rspack (experimental)
• Client Instrumentation hook
• Navigation hooks

This guide will cover how you can build APIs with Next.js, including setting up your project, understanding the App Router and Route Handlers, handling multiple HTTP methods, implementing dynamic routing, creating reusable middleware logic, and deciding when to spin up a dedicated API layer.

Next.js 15.2 includes updates for debugging errors, metadata, Turbopack, and more:

• Redesigned error UI and improved stack traces
• Streaming metadata
• Turbopack performance improvements
• React View Transitions (experimental)
• Node.js Middleware (experimental)

We’re working on a simple and powerful caching model for Next.js. In a previous post, we talked about our journey with caching and how we’ve arrived at the 'use cache' directive.

Next.js 15.1 introduces core upgrades, new APIs, and improvements to the developer experience including:

• React 19 (stable)
• Improved Error Debugging
• after (stable)
• forbidden / unauthorized (experimental)

Frontend performance can be hard to get right. Even in highly optimized apps, the most common culprit by far is client-server waterfalls. When introducing Next.js App Router, we knew we wanted to solve this issue. To do that, we needed to move client-server REST fetches to the server using React Server Components in a single roundtrip. This meant the server had to sometimes be dynamic, sacrificing the great initial loading performance of Jamstack. We built partial prerendering to solve this tradeoff and have the best of both worlds.

Our mission to create the best developer experience continues with Next.js 15, featuring:

• @next/codemod CLI
• Async Request APIs (Breaking)
• Caching Semantics (Breaking)

Next.js has been designed for gradual adoption. With Next.js, you can continue using your existing code and add as much (or as little) React as you need. By starting small and incrementally adding more pages, you can prevent derailing feature work by avoiding a complete rewrite.

Many companies need to modernize their tech stack to reduce costs, increase developer productivity, and provide the best experience for their customers. Component-driven development has greatly improved the deployment velocity and reusability of modern codebases.

And with over 8 million downloads/month, React is the leading component-driven choice for developers. Next.js, the React framework for production, enables you to incrementally adopt React.
