CodeDuel puts you head-to-head against Claude AI on real coding problems. Same problem. Same time. One winner. You write your solution in a VS Code-style editor. Claude generates its solution simultaneously. Both run against the same test cases. Scored on correctness, speed, and code quality. After every duel Claude explains its approach so you actually learn something. Free to start. Pro at $6/month ā 7-day free trial, no credit card required.
Hey Product Hunt! š Nahom here, the solo developer behind CodeDuel.
I built this after noticing a pattern in myself ā I was shipping faster with AI tools but struggling more when I had to code without them. Interview prep felt harder. Whiteboard problems felt rustier. I wanted an honest answer to "are my skills actually slipping?"
So I built CodeDuel. You compete against Claude AI on real coding problems. Same problem, same time, one winner. Claude explains its approach after every duel so you learn something regardless of whether you win or lose.
The part I'm most proud of is the scoring system ā you're evaluated on correctness, speed, AND code quality. Claude looks at both solutions and tells you specifically where yours was stronger or weaker. It's more honest feedback than most code reviews.
A few things I'd genuinely love feedback on:
- What problem categories are missing that you'd want to practice?
- Is $6/month the right price for a developer tool like this?
- Would you use a daily challenge feature where everyone gets the same problem?
7-day free trial, no credit card required ā would love for you to try it and tell me your ELO rating after 5 duels.
