I'm sure some of the best engineers out here are having a hard time standing out nowadays. It's hard to evaluate and improve your skills, when AI is writing the code. Especially when a junior dev is sitting by your side and "accomplishing" 2x more than you.
I didn't like this reality where the line between real talent and AI slop is blurring, so I decided to create a challenge, purely for the community, that is made to truly give a stage for talented devs to stand out in the age of AI.
We encourage devs to bring their agents with them, because the challenge is built to not be solvable only with AI agents.
today the challenge is live for the next 24 hours. couldn't be more excited for some of you to check it out and give some honest, no-filter feedback.
head-up - it is hard :)

Coding game with real-time multiplayer combat—more engaging than algorithmic challenges alone.
Playable agent arena with real-money markets and spectating beats abstract benchmarks.
Instead of wrestling with raw mitmproxy output, this tool gives a purpose-built UI that shows system prompts, tool definitions, token accounting, streaming responses and tool calls — all in real time. The one-liner shell setup, keyboard shortcuts, and token breakdown make debugging Claude Code conversations startlingly quicker, though it’s inherently a local MITM (trust the generated CA) and is narrow by design to Anthropic’s workflow.
Micro-challenge approach beats passive video tutorials for learning p5.js.
Annual AI game jam with $35k prizes requires 90% of code be written by AI tools.
