pyramid_debugtoolbar provides a debug toolbar useful while you're developing your Pyramid application.

Note that pyramid_debugtoolbar is a blatant rip-off of Michael van Tellingen's flask-debugtoolbar (which itself was derived from Rob Hudson's django-debugtoolbar). It also includes a lightly sanded down version of the Werkzeug debugger code by Armin Ronacher and team.


The documentation of the current stable release of pyramid_debugtoolbar is available at


For a demonstration:

  • Create a virtualenv:

    $ VENV=$(pwd)/venv # just set the path to our virtualenv
    $ virtualenv --python=python2.7 $VENV
  • Clone the Pyramid trunk:

    $ git clone
  • Install the Pyramid trunk into the virtualenv:

    $ cd pyramid
    $ $VENV/bin/python develop
  • Clone the pyramid_debugtoolbar trunk:

    $ git clone
  • Install the pyramid_debugtoolbar trunk into the virtualenv:

    $ cd pyramid_debugtoolbar
    $ $VENV/bin/python develop
  • Install the pyramid_debugtoolbar/demo package into the virtualenv:

    $ cd demo
    $ $VENV/bin/python develop
  • Run the pyramid_debugtoolbar package's demo/ file using the virtualenv's Python:

    $ $VENV/bin/python
