The Debug Variable
As of v1.7.6, Statamic now creates a {{ _debug }} variable on every page. This variable is a named-list, which currently contains the following information:

Using _debug
A useful idea for displaying debug information is to dump it into an HTML comment at the top of your pages when in a development environment. First, you’ll want to set up a development environment. For this example, let’s assume that our environment matches a dev environment.
Next, at the top of your default layout file, just inside of your HTML tag, put the following:
<html>
{{ if is_dev }}
<!--
debug information
---------------------------------------------------------
{{ _debug|dump }}
---------------------------------------------------------
-->
{{ endif }}
Now refresh your page and view the source. (You can also view the source of this page, we’ve added the _debug stuff to it just for you to look at.)
You can also access any of the individual _debug variables with the colon-syntax, for example, the current template can be displayed with {{ _debug:template }}.
