Awesome WebSocket CLient - an interactive command line client for testing websocket servers (by thehowl)
Hmm. We don't have a WebSocket client available right, it will be coded in the next part of this article. Unluckily, curl does not have a full support for the WebSocket protocol (it can receive but not send data). Instead, we can install the browser-websocket-client open-source plugin available on the Chrome Web Store. Are you Firefox friendly? You can use Weasel and its still open-source. If you prefer a command line tool, you can also check websocat or claws.

Project mention: Show HN: Termtrace – Record and replay terminal sessions as traces | news.ycombinator.com | 2026-04-04I often end up repeating the same steps in the terminal and later can’t reproduce what I did.
