Hey, I made this! I also made this other thing on HN today (https://news.ycombinator.com/item?id=37062422), really cool to see ArpChat as well (guess someone went through my profile). It was a super fun project and I learned a lot about networking.
I actually got a chance to use it in a totally-offline setting a bit ago, which was fun! ... however, I then found a major bug that was causing tons of latency, and I fixed it but I haven't gotten around to building new artifacts yet, so you might want to build from scratch if you're planning on testing it out in a real setting for some reason. I also added fun username colors and message times. I promise I'll upload a new release soon!

If you're interested, I wrote an article about a year ago about how ArpChat works: https://kognise.dev/writing/arp
