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.
macOS:
brew install hey
.hey runs provided number of requests in the provided concurrency level and prints stats.
It also supports HTTP2 endpoints.
Usage: hey [options...] <url>

-n Number of requests to run. Default is 200.
-c Number of workers to run concurrently. Total number of requests cannot
be smaller than the concurrency level. Default is 50.
-q Rate limit, in queries per second (QPS) per worker. Default is no rate limit.
-z Duration of application to send requests. When duration is reached,
application stops and exits. If duration is specified, n is ignored.

"csv" is the only supported alternative. Dumps the response
