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.

A multi-file IDE with whiteboard, structured scoring, private notes and code playback so interviewers can assess real problem solving rather than puzzle recall.
Automated pre-screens built from practical engineering tasks, with clear scoring that helps recruiters move qualified candidates forward faster.
AI assistants work with code context, prompts are captured, and AI reviewers rank video or code submissions against your own rubric.
Adaptive tests, activity monitoring, real-time alerts and playback reports help detect suspicious behaviour without manual review.
