How the Comparison Works

Each package is fetched in real-time from the npm registry, Bundlephobia and GitHub. Downloads come directly from the official npm downloads API. Bundle sizes are measured by Bundlephobia which installs each package and measures the compiled output. Health scores use the same scoring engine as our Package Health tool — considering publish recency, download trends, GitHub activity, issue resolution and dependency count.

A winner is calculated per metric — the package with the most weekly downloads wins the popularity category, the smallest gzip size wins the bundle category, and so on. An overall winner is the package that wins the most individual categories.
