    Using the convenience script (macOS and Linux)

    • The script requires root or sudo privileges to move ddosify binary to /usr/local/bin.
    • The script attempts to detect your operating system (macOS or Linux) and architecture (arm64, x86, amd64) to download the appropriate binary from the releases page.
    • By default, the script installs the latest version of ddosify.
    • If you have problems, check common issues
    • Required packages: curl and sudo
    curl -sSfL https://raw.githubusercontent.com/ddosify/ddosify/master/scripts/install.sh | sh

    Go install from source (macOS, Linux, Windows)

    go install -v go.ddosify.com/[[email protected]](/cdn-cgi/l/email-protection)

    Easy Start
    This section aims to show you how to use Ddosify without deep dive into its details easily.

    1. Simple load test
    ddosify -t target_site.com  

    The above command runs a load test with the default value that is 100 requests in 10 seconds.
    2. Using some of the features

    ddosify -t target_site.com -n 1000 -d 20 -p HTTPS -m PUT -T 7 -P http://proxy_server.com:80  

    Ddosify sends a total of 1000 PUT requests to https://target_site.com over proxy http://proxy_server.com:80 in 20 seconds with a timeout of 7 seconds per request.
    3. Scenario based load test

    ddosify -config config_examples/config.json  

    Ddosify first sends HTTP/2 POST request to https://test_site1.com/endpoint_1 using basic auth credentials test_user:12345 over proxy http://proxy_host.com:proxy_port and with a timeout of 3 seconds. Once the response is received, HTTPS GET request will be sent to https://test_site1.com/endpoint_2 along with the payload included in config_examples/payload.txt file with a timeout of 2 seconds. This flow will be repeated 20 times in 5 seconds and response will be written to stdout.
    You can configure your load test by the CLI options or a config file. Config file supports more features than the CLI. For example, you can't create a scenario-based load test with CLI options.

    Load Types

    ddosify -t target_site.com -l linear


    Note: If the request count is too low for the given duration, the test might be finished earlier than you expect.

    ddosify -t target_site.com -l incremental



    ddosify -t target_site.com -l waved


    Config File
    Config file lets you use all capabilities of Ddosify.
    The features you can use by config file;

    • Scenario creation
    • Payload from a file
    • Extra connection configuration, like keep-alive enable/disable logic
    • HTTP2 support
    ddosify -config <json_config_path>  

    There is an example config file at config_examples/config.json. This file contains all of the parameters you can use. Details of each parameter;

    • request_count optional
      This is the equivalent of the -n flag. The difference is that if you have multiple steps in your scenario, this value represents the iteration count of the steps.
    • load_type optional
      This is the equivalent of the -l flag.
    • duration optional
      This is the equivalent of the -d flag.
    • proxy optional
      This is the equivalent of the -P flag.
    • output optional
      This is the equivalent of the -o flag.
    • steps mandatory
      This parameter lets you create your scenario. Ddosify runs the provided steps, respectively. For the given example file step id: 2 will be executed immediately after the response of step id: 1 is received. The order of the execution is the same as the order of the steps in the config file.
      Details of each parameter for a step;
    • id mandatory
      Each step must have a unique integer id.
    • url mandatory
      This is the equivalent of the -t flag.
    • protocol optional
      This is the equivalent of the -p flag.
    • method optional
      This is the equivalent of the -m flag.
    • headers optional
      List of headers with key:value format.
    • payload optional
      This is the equivalent of the -b flag.
    • payload_file optional
      If you need a long payload, we suggest using this parameter instead of payload.
    • auth optional
      Basic authentication.
    "auth": {  
    "username": "test_user",  
    "password": "12345"  
    • others optional
      This parameter accepts dynamic key: value pairs to configure connection details of the protocol in use.
    "others": {  
    "keep-alive": true,              // Default false  
    "disable-compression": false,    // Default true  
    "h2": true,                      // Enables HTTP/2. Default false.  
    "disable-redirect": true         // Default false
