This is a lightweight, dynamically-rendered user interface written in AngularJS 1.5 and Bootstrap that allows developers to see and to traverse a HAL Hypermedia API.  This has proven to be extremely useful to our back-end team, who can add resources/routes/forms to the API and can then check the HAL browser to see if their implementation was executed correctly.   This has also been used and proven very useful by customers who wanted to leverage our tickets API for their own internal needs.
