Implied technologies

Detecting Cowboy implies these are in the stack too - a report lists them alongside it.

How we audit Cowboy

We measure the detected version against Cowboy's release history and grade the surrounding stack with a Lighthouse-grade quality audit. Weak or outdated links weigh more - one risky dependency can pull the whole score down.
