|

|
|
[lekoala/silverstripe-debugbar](https://github.com/lekoala/silverstripe-debugbar) module.
|
|
It similar to the browser "developer toolbar", and adds itself to the bottom of the screen
|
|
when your site is in development mode. It shows you render times, database queries,
|
|
session variables, used templates and much more.
