DebugBar
DebugBar makes it easier to debug Laravel applications. This is why it's included by default in your application and it only runs when your APP_DEBUG
is enabled.
Known limitation
There's a known issue which is that API endpoints are not displayed in debugbar, because debugbar must inject JavaScript, which would break the API call.

Checkout this thread on github for temporary workarounds regarding this limitation.
