About
A Storybook addon that provides real-time performance monitoring for UI components. It tracks comprehensive metrics including frame timing, input responsiveness, memory usage, and React profiling to help developers optimize component performance.
Why it made the leaderboard
Adds real-time performance monitoring to your Storybook — frame timing, input responsiveness, memory usage, and React profiling per story, so you catch slow components before they ship. Works with React and non-React projects.
