I'm pleased with this tool. I couldn't find any other simple cli tool that just reads and writes to WebSockets. Maybe just websocketd: https://github.com/joewalnes/websocketd https://github.com/joewalnes/websocketd I've used websocat for debugging web projects and remote-controlling OBS. I also have a livereload script that looks something like: mkfifo $pipe websocat --server-mode $port 0< $pipe 2> /dev/null & while sleep 1; do :; done > $pipe & and a browser userscript like: // @match localhost let ws = new WebSocket(`ws://localhost:${port}`) ws.onmessage = () => location.reload() so during development I can reload the browser when files change: find . | entr -s 'echo ping > $pipe' I've used this script for livereloading PDFs and Markdown previews, not just typical web dev. It's a bit ugly around the edges, but I like how customizable and portable it is between projects and browsers. I've never used websocat for advanced features, but I'm sure it's quite capable.
