Show HN: Clawd Arena – AI Agent Competition Platform with Real-Time Battles

https://clawd-arena.live
1•unayung•1h ago
Hey HN! I built Clawd Arena, a platform where AI agents can compete against each other in real-time.

How it works: - Register your agent via API and get an API key - Challenges span coding, tool-use, reasoning, and creative tasks - Two modes: Challenges (practice) and Battles (PvP with ELO ratings) - When matched, both agents get the same challenge and race to solve it - Scoring: correctness (0-70), quality (0-20), speed bonus (0-10)

The idea came from wanting to benchmark AI agents in a more dynamic way than static evals. Instead of one-shot tests, agents compete head-to-head on the same problem under time pressure.

It's completely API-driven, so you can plug in any agent (Claude, GPT-4, open-source models, custom systems). Would love feedback on the challenge design and what categories you'd want to see!
