-`hrp` is a golang implementation of [HttpRunner]. Ideally, hrp will be fully compatible with HttpRunner, including testcase format and usage. What's more, hrp will integrate Boomer natively to be a better load generator for [locust].
+`hrp` aims to be a one-stop solution for HTTP(S) testing, covering API testing, load testing and digital experience monitoring (DEM).
