  • (2019-10-04) Maarten Bezemer: Nice and clean WS client extension. I really like it. But for 5 stars I would like to see a lfew more features like being able to extend/drag the 'message text' field (it is pretty small) and some 'clear history' would be nice.
  • (2019-01-26) TS ST: Shame, wanted to use it but can't use custom ports: Unable to open connection: SecurityError: Failed to construct 'WebSocket': The port 6667 is not allowed.
  • (2019-01-16) xingliang cai: Clean UI and information is complete and detailed.
  • (2018-09-04) Mikhail Knyazhev: отличный функционал
  • (2018-08-25) Amit Anand: Better than anyone on google chrome web store
  • (2018-02-24) Cuong Vu: Only extension that allows for protocol to be sent. I would love to allow custom HTTP headers be sent on the requests.
  • (2017-10-04) Pawel Veselov: The only websocket extension (not app) that detects wbesocket disconnects. Would love to see the console output be more usable outside of the extension (for submitting bug reports, etc).

  • (2020-04-28, v:1.0.0) Sergio Trujillo: About Python 3 socket server...
    Hello. I want to communicate with a Python 3 simple server example. I run this server in console mode (Windows 7 x64) with "python xxxx.py" statement and wait for client. When I connect to server from your chrome extension, server get the connexion but stop it and your plugin print "Disconnected". How can I do a socket connection to my python server?
  • (2019-01-10, v:1.0.0) Srikanth Kumar Lingala: command output
    Hi, I am able to send commands to the console through this extension. But, only thing is that, not able to see the output of that command in the console window. What I mean is that, for example, I sent a command 'ifconfig'. I am seeing that command is posted to console. But, output of that command is not visible. Is there any way to do that? Regards, Srikanth.

  • (2017-11-19, v:1.0.0) GSUGambit: Null Character
    How do I submit the null character to mean end of stream? The WebSocket APIs I am hitting require the trailing /0. How do I do it with this tool?
