Hey everyone,

First of all, a huge shoutout to Avinash for the legendary long-form tutorials! The depth of the AI development tools built on this channel is absolutely unmatched.

Since we’ve seen some incredible deep dives into AI coding tools here, I want to drop a project suggestion for a future course or video that I think the entire community would love: A full-stack clone of LM Arena's "Code Arena" (arena.ai).

For those who haven't seen it, the concept is brilliant and highly viral: a user inputs a single prompt, and two different AI agents generate a web application simultaneously side-by-side in real-time sandboxes. Users can then interact with both live apps and vote on which one performed better.

What makes arena.ai so fascinating—and why it would make an amazing tutorial—is its incredibly simple, clean, and distraction-free environment. It completely strips away the heavy complexity of traditional IDEs. It makes the magic of AI web building lightweight, highly engaging, and accessible to absolutely everyone.

It perfectly combines advanced AI agent orchestration with a trending, community-driven concept.

What do you guys think? If you want to see  Avinash take on this challenge and break it down for us, please drop an upvote and leave your thoughts below!
