Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.

Sekai is a community platform for interactive mini-apps, games and creative toys that run instantly in the browser or on mobile. A feed of trending creations sits next to a creation studio that lets anyone build, remix and share their own.
A constantly updated feed of trending creations, top creators and curated categories such as meme, relax, strategy, action and puzzle.
A studio that lets you build a playable mini-app, then publish it to the community in minutes.
Take any published creation, change it and re-release your version — the engine behind most of the catalogue.
Everything runs in the browser with no install, and the same creations work on iPhone and Android through the Sekai app.
