The following API modules provide support for extending Chrome Developer Tools:

• experimental.devtools.audits
• experimental.devtools.console
• experimental.devtools.inspectedWindow
• experimental.devtools.network
• experimental.devtools.panels

Caution: Don't depend on these experimental APIs. They might disappear, and they will change. Also, the Chrome Developer Dashboard doesn't allow you to upload extensions that use experimental APIs.

How to use DevTools APIs

1. Developer Tools APIs are currently experimental, so please start with the steps for using experimental extension APIs.
2. Specify the "devtools_page" field in your extension's manifest and make sure you have "experimental" permission:

   {
     "name": ...
     "version": "1.0",
     "minimum_chrome_version": "10.0",
     "devtools_page": "devtools.html",
     "permissions": [ "experimental" ... ],
     ...
   }
   

3. An instance of the devtools_page specified in your extension's manifest will be created for every Developer Tools window opened. The page may add other extension pages as panels and sidebars to the Developer Tools window using experimental.devtools.panels API.
4. The chrome.experimental.devtools.* API modules are available only to the pages loaded within the Developer Tools window. Content scripts and other extension pages do not have these APIs. Thus, the APIs are available only through the lifetime of the Developer Tools window.
5. The APIs available to extension pages within the Developer Tools window include all experimental.devtools modules listed above and chrome.extension API. Other extension APIs are not available to the Developer Tools pages, but you may invoke them by sending a request to the background page of your extension, similarly to how it's done in the content scripts.
6. Give us feedback! Your comments and suggestions help us improve the APIs and decide which ones should move from experimental to supported.
