RSC Boundary provides a visual tool to delineate the boundaries between Server Components and Client Components directly within the browser of Next.js App Router applications. This lightweight development tool simplifies the process of distinguishing between server-rendered regions and client subtrees, enhancing clarity and improving efficiency during development.

Adding the RscBoundaryProvider to your root layout activates outlines, labels, and a dedicated panel that easily maps these components, eliminating the need for detailed annotations on every file or confusion derived from the file structure alone.

Key Features

• Enhanced Clarity: Understand the separation between Server Components, which possess no client fibers, and Client Components that utilize hydration. RSC Boundary visually surfaces this distinction, making the mental model more tangible while building your application.
