HTTP(s) load generator, ApacheBench (ab) replacement

boom

boom is a tiny program that sends some load to a web application. It's similar to Apache Bench (ab), but with better availability across different platforms and a less troubling installation experience.

boom is originally written by Tarek Ziade in Python and is available on tarekziade/boom. But, due to its dependency requirements and my personal annoyance of maintaining concurrent programs in Python, I decided to rewrite it in Go.

Installation

Simple as it takes to type the following command:

go get github.com/rakyll/boom

Usage

boom supports custom headers, request body and basic authentication. It runs provided number of requests in the provided concurrency level, and prints stats.

Usage: boom [options...] <url>

Options:
  -n	Number of requests to run.
  -c	Number of requests to run concurrently. Total number of requests cannot
  		be smaller than the concurency level.
  -q    Rate limit, in seconds (QPS).
  -t    Time limit in seconds. boom will stop after s seconds if specified.

  -m	HTTP method, one of GET, POST, PUT, DELETE, HEAD, OPTIONS.
  -h	Custom HTTP headers, name1:value1;name2:value2.
  -d	HTTP request body.
  -T	Content-type, defaults to "text/html".
  -a	Basic authentication, username:password.
  
  -allow-insecure	Allow bad/expired TLS/SSL certificates.  

This is what happens when you run boom:

% boom -n 1000 -c 100 https://google.com
