Symfony Profiler
The Symfony Profiler is a powerful debugging tool when building applications with Symfony. The profiler collects information when handeling HTTP requests via the controllers.
The Feral Slack package contains the
ProfilerProcessSubscriber
event handler which listens for the process and node events to illustrate the process
flow that was executed.

As noted by the Symfony team, the profiler should never be used in production.
