Want this built into your product? AI agents write the code, an engineer directs them: https://vibecoding.tech/services?utm_source=21st&utm_medium=component Book a call and say promo code 21ST to get a free 3-day development trial. Score bars with +/-std whiskers plus numeric economy columns (cost/tokens/steps), one row per model run, with version and Best/All-effort-levels toggles, model filter, and rank-morphing rows. Answers: "Who leads on score, with what confidence spread, and what does that score cost?"
Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Leaderboard Table to your project and fits it to your theme.

How Leaderboard Table is used: the demo's code. The component's own source comes with a free account.
