wsget is a command-line tool for interacting with a WebSocket server. It supports plain text and JSON messages and can save the output of the session into a file.

Compiled executables can be downloaded from here.

go install github.com/ksysoev/wsget/cmd/wsget@latest

brew tap ksysoev/wsget
brew install wsget

To use wsget, you need to specify the WebSocket URL:

wsget wss://ws.postman-echo.com/raw

You also can pass the initial request as part command line argument by using flag -r

wsget wss://ws.postman-echo.com/raw -r "Hello world!"

By default, wsget will print the data received from the WebSocket server only to the console. You can also save the data to a file using the -o flag:

wsget wss://ws.postman-echo.com/raw  -o output.txt

Example:

wsget "wss://ws.derivws.com/websockets/v3?app_id=1" -r '{"time":1}'
Use Enter to input request and send it, Ctrl+C to exit
->
{
  "time": 1
}
<-
{
  "echo_req": {
    "time": 1
  },
  "msg_type": "time",
  "time": 1698555261
}

wsget provides a possibility for customization. You can create your sets of macros with a configuration file. the file should be located at ~/wsget/macro/your_configuration.yaml. wsget will read all files from this directory and use only configuration files that match the WebSocket connection hostname.

version: "1"
domains:
    - example.com
macro:
    ping:
        - |-
          send {
              "ping": 1,
          }
        - wait 5

• edit {"ping": 1} opens request editor with provided text
• send {"ping": 1} sends requests to WebSocket connection
• wait 5 waits for responses or provided time out, whatever comes first. If the timeout is reached then an error will be returned. if 0 is provided command will wait response without a time limit
• exit interrupts the program execution
• repeat 5 send {"ping": 1} repeat provided command or macro defined number of times
• sleep 1 sleeps for the provided number of seconds

Macro support Go template language. It provides a possibility to pass arguments to your macro command and substitute or adjust the behavior of your macro commands.
