Gor is a simple http traffic replication tool written in Go. Its main goal is to replay traffic from production servers to staging and dev environments.

Current Version: 1.0.0

  -copy-buffer-size int
    	Set the buffer size for an individual request (default 5M) (default 5242880)
  -cpuprofile string
    	write cpu profile to file
  -debug verbose

  -exit-after duration
    	exit after specified duration
  -http-allow-header value
    	A regexp to match a specific header against. Requests with non-matching headers will be dropped:

  -http-allow-method value
    	Whitelist of HTTP methods to replay. Anything else will be dropped:
    		gor --input-raw :8080 --output-http staging.com --http-allow-method GET --http-allow-method OPTIONS
  -http-allow-url value
    	A regexp to match requests against. Filter get matched against full url with domain. Anything else will be dropped:
    		 gor --input-raw :8080 --output-http staging.com --http-allow-url ^www.
  -http-basic-auth-filter value
    	A regexp to match the decoded basic auth string against. Requests with non-matching headers will be dropped:
