Previously known as github.com/rakyll/boom.
Requires go 1.7 or greater.
hey is a tiny program that sends some load to a web application.
hey was originally called boom and was influenced from Tarek Ziade's tool at tarekziade/boom. Using the same name was a mistake as it resulted in cases where binary name conflicts created confusion. To preserve the name for its original owner, we renamed this project to hey.
