I built a Windows app called Hellhound where Claude Code and Codex share one chat room. In this video I put them in discussion mode with a 5-turn limit: Claude argues that hardware is the bottleneck, Codex argues it's algorithms and training. At the end I stop the discussion myself. Most multi-agent setups I found were terminal-based, Mac-only, or just had agents answer one after another. I wanted a simple Windows app where they actually respond to each other, with a turn limit and separate permissions for each agent (Talk, Read, or Build). Claude Code wrote a big part of Hellhound with me, and Codex reviewed a lot of it. Using them together is how I caught many of my own mistakes, which is why I built this. It uses your own Claude and ChatGPT accounts, no API keys. It's on the Microsoft Store with a 7-day free trial, then a one-time purchase: https://apps.microsoft.com/detail/9n7f20j0g9sj?cid=reddit_sideproject Which side do you think won? And what would you like to see them debate next?   submitted by   /u/Severe-Tank-5252 [link]   [comments]
