Debug toolbar for Plone

Introduction provides a wealth of debug information about a running Plone site at your fingertips. Simply install it in your build (e.g. by adding it to the eggs list in your Buildout and re-running buildout) and install it into your Plone site.

You should now see a Debug link at the top of your site. Click it to open the debug drawer. Click on a panel to view relevant information.

Panels include:

  • Context, showing information about the current content object
  • Interactive, providing an interactive Python prompt through which you can interact with the current context (only available to users with the Manage portal permission)
  • Request, showing information about the request that produced the current page
  • Response, showing informationa about the response that produced the current page
  • Published, showing information about the page template or view that was published
  • Theme, showing information about the current theme and browser layers
  • User, showing information about the current user
  • Workflow, showing information about workflow and security
  • Zope, showing information about how the Zope server is configured
  • Versions, listing the versions of every package known to the Zope process


The debug toolbar provides a lot of information about your Plone site that you may not want the world to know. It could also have a noticable performance impact, and for users with the Manage portal permission it provides access to an interactive interpreter where arbitrary Python statements can be executed, allowing a user to bypass Zope security.

In other words: Do not install this package on your production server.


Each panels is included as a viewlet. You can register new panels using a viewlet registration like this:
