Magento Debug Toolbar

Based on robhudson's awesome work ( we've created a debug toolbar for Magento. It is installed as a Magento module without hacking Magento's core.

Basic features are implemented and few others will come soon. Check the screenshots for current features:

Or demo video on YouTube:


A) Via Modman - Recommended (

1) Install Modman:

bash < <(wget -O -


bash < <(curl -s
source ~/.profile

2) Allow symlinks for the templates directory (required for installation via Modman)

3) Install Debug Toolbar module:

cd [magento root folder]
modman init
modman clone
  • Make sure you've cleaned Magento's cache to enable the new module; hit refresh

How to update

I'm pretty lazy and I don't like to create Magento Connect packages. With modman you can effortlessly grab the latest changes from github.

modman update magneto-debug
  • Clean Magento's cache to make sure new changes will be enabled.

B) Via Magento Connect

Extension is not updated regularly. I recommend using modman.

cd [magento root folder]
sudo ./mage install community MagnetoDebug

Magento Connect extension package is available here:


  • Now available in Admin (1.0.1 RC - fancy for I'm laizy to create Magento Connect package)
  • Magento module listing; Toggle Magento modules on the fly
  • Search configuration keys
  • Display peak memory usage, script execution time
  • Request information (controller name, action name, cookies variables, session variables, GET and POST variables)
  • Models instantiated
  • SQL queries executed for current request; ability to see queries' result or queries' execution plan (EXPLAIN)
  • List Magento configuration
  • Print layout handles for current request
  • Find xml files where a specific layout handle is defined
  • Created blocks, their associated templates; Preview templates' source code
  • Quick actions:
    • Toggle template hints
    • Clear cache
    • Toggle inline translation


We're working to correct these:

  • To enable SQL profiler manually you have to add in your local.xml profiler tag <profiler>1</profiler> under connection, like in the example below:

  • Disable SQL Profiler is not working, but Enable SQL Profiler works like a charm (or not)
You can’t perform that action at this time.
