 ## What is Vite DevTools?
 
-Vite DevTools is a comprehensive set of developer tools for visualizing and analyzing your Vite build process. It provides deep insights into your build pipeline, module dependencies, and build metadata, helping you understand and optimize your Vite applications.
+Vite DevTools is a devtools framework for the Vite ecosystem. Instead of each tool building its own devtools from scratch, Vite DevTools provides shared infrastructure — a unified dock system, type-safe RPC, shared state management, and flexible UI hosting — so that different tools compose together seamlessly, users get a consistent experience, and tool authors can focus on what makes their integration unique.
+
+Any Vite plugin can hook into Vite DevTools with just a few lines of code, instantly gaining access to the full platform: panels, action buttons, server-client communication, and more.
+
+### Built-in Integrations
+
+- **[DevTools for Rolldown](/rolldown/)** — Build analysis, module graphs, chunks, assets, plugins, and performance insights
+- **DevTools for Vite** — Vite-specific developer tools *(in development)*

+
+- **[Nuxt DevTools v4](https://github.com/nuxt/devtools)** — Built on top of Vite DevTools Kit
+- **[Oxc Inspector](https://github.com/yuyinws/oxc-inspector)** — Integrates via DevTools Kit with custom RPC functions
+- **[UnoCSS Inspector](https://github.com/unocss/unocss)** — Dock integration for UnoCSS
+- **[vite-plugin-vue-tracer](https://github.com/antfu/vite-plugin-vue-tracer)** — Action button that triggers a DOM inspector

 ## Current Limitations
 
 > [!NOTE]
-> Vite DevTools is currently in active development with the following limitations:
+> Vite DevTools is currently in active development.
 
-- **Build mode only**: Currently works with Vite-Rolldown's build mode

+- **[DevTools for Rolldown](/rolldown/)**: Currently supports build mode only, requires Vite 8+
+- **Dev mode**: Dev mode support is planned for future releases
 
 ## Architecture Overview
 
 Vite DevTools consists of several core packages:
 
-- **`@vitejs/devtools`**: The main entry point and CLI
-- **`@vitejs/devtools-kit`**: Utilities and types for building custom integrations
-- **`@vitejs/devtools-rolldown`**: Built-in UI panel for Rolldown
+- **`@vitejs/devtools`**: The core framework, CLI, and runtime hosts
+- **`@vitejs/devtools-kit`**: Vite DevTools Kit — utilities and types for building custom integrations

+- **`@vitejs/devtools-vite`**: DevTools for Vite *(in development)*
 - **`@vitejs/devtools-rpc`**: RPC layer for server-client communication
 
-For more details on extending Vite DevTools, see the [DevTools Kit documentation](/kit/).
+Third-party integrations like [Oxc Inspector](https://github.com/yuyinws/oxc-inspector) can also integrate via the DevTools Kit plugin API.

+# DevTools for Rolldown
+
+DevTools for Rolldown (`@vitejs/devtools-rolldown`) is a built-in integration that provides comprehensive build analysis for Vite projects using Rolldown. It comes included with Vite DevTools out of the box.
+
+> [!WARNING]
+> DevTools for Rolldown currently only supports build mode of Vite 8+.
+> Dev mode and Vite versions under 8 are not supported yet.
+
+## What It Does
+
+DevTools for Rolldown gives you deep insights into your Rolldown-powered build process:
+
+- **Module Analysis** — Visualize module graphs, dependencies, and transformation flows
+- **Plugin Insights** — Inspect plugin hook costs and processed modules
+- **Chunk & Asset Analysis** — Explore build output with list, graph, treemap, and flamegraph views
+- **Package Detection** — Detect duplicated packages and analyze dependency sizes
+- **Session Compare** — Compare bundle changes across builds
+
+See the [Features](/rolldown/features) page for a detailed walkthrough with screenshots.
+
+## Getting Started
+
+DevTools for Rolldown is automatically available when you set up Vite DevTools. Follow the [Getting Started](/guide/) guide to install and configure Vite DevTools, then the Rolldown build analysis panels will appear in the dock.
