Short Description
Pla is HTTP(S) load generator, written in Go
Full Description

pla

Pla 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.

Pla is originally written rakyll and is available at rakyll/boom.
Due to some issues like memory consumption I decided to fork it.

Installation

Simple as it takes to type the following command:

go get -u github.com/sschepens/pla

Usage

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

Usage: pla [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).
  -o  Output type. If none provided, a summary is printed.
      "csv" is the only supported alternative. Dumps the response
      metrics in comma-seperated values format.

  -m  HTTP method, one of GET, POST, PUT, DELETE, HEAD, OPTIONS.
  -h  Custom HTTP headers, name1:value1;name2:value2.
  -t  Timeout in ms.
  -A  HTTP Accept header.
  -d  HTTP request body.
  -T  Content-type, defaults to "text/html".
  -a  Basic authentication, username:password.
  -x  HTTP Proxy address as host:port.

  -readall              Consumes the entire request body.
  -allow-insecure       Allow bad/expired TLS/SSL certificates.
  -disable-compression  Disable compression.
  -disable-keepalive    Disable keep-alive, prevents re-use of TCP
                        connections between different HTTP requests.
  -cpus                 Number of used cpu cores.
                        (default for current machine is 1 cores)

This is what happens when you run Pla:
