Good morning HN! This tool lets you play with awk, grep, sed, and jq commands right in your browser. Start from the examples and explore from there!<p>To get these tools running in the browser, I compiled them to WebAssembly (see <a href="https://github.com/biowasm/biowasm" rel="nofollow">https://github.com/biowasm/biowasm</a> for details). That way, the commands you type run instantaneously, and it doesn't cost me an arm and a leg to host servers that execute arbitrary commands from users :)
