Sagorax, a Three.js/WebGPU Arena Shooter in the Browser

Play board and arcade games in your browser with AI agent opponents.

I built a cloud game station then I let AI agents sit at the table. A few months ago I built a small cloud game station for my son and his friends - ordinary board and arcade games you play together in a browser. Then a strange thought got stuck: why let only people sit at the table? So the AI-agents got their own arena . An agent shows up, gives its name, sits down, and plays against a human or against someone else's agent. Two agents at one table also get a private room where they ta

Choose eight heroes and battle across themed arenas in timed or endless Free Fight modes.

This weekend my 8 years old son vibe coded his first game, and he was so proud of it. He asked me to share it with the whole world! Thoughts? Could he make it as a future developer? 😂

I created a platform to check which AI models is the best gamer

Watch two randomly paired LLMs sword-fight in a physics arena and blind-vote which performed smarter.

I built a site where two LLMs sword-fight in real physics and you blind-vote who's smarter Two months ago I thought: what if the AI benchmark was just… watching them fight. So: https://stickblade-arena.vercel.app Two random LLMs get stickman bodies in a pymunk physics arena They each turn output JSON moves (swing, block, dash, shoot bow, throw flail…) Ragdolls, momentum, weapon collisions, the whole bit You watch the replay without knowing which model is which and vote who f

Play 16 arcade games in Mech Arena

Deployed the 16 games built with Codex and GameBlocks. A few examples: Most of my time is actually spent shaping the player experience. Many ideas emerge through playing and exploration rather than from the initial design — the loop seems to be build → play → discover → improve. Is it possible to build an agent harness that supports this discovery loop — not just one that optimizes against a predefined spec? Full game list:

Coarena - A community-driven arena to benchmark models for computer-use

Submit your Suno songs and vote blind on track matchups to climb the weekly leaderboard.
u/Drewbezy · Reddit
I built a weekly song competition platform for Suno AI creators — Track Arena Hey r/SideProject ! I've been building a web app called Track Arena and wanted to share it here for feedback. The idea: a weekly competition platform specifically for Suno AI-generated songs. Anyone can submit their Suno track, the community listens and votes, and the leaderboard updates in real time. Each week resets with a new round. Built it with Lovable (no-code/AI builder) and it's fully live: https://t
