What each one is

The product in its own terms, so the numbers below have context.

JSR

An open-source package registry for JavaScript and TypeScript that publishes ECMAScript modules natively. It works across multiple JavaScript runtimes including Node.js, Deno, Bun, and Cloudflare Workers, with built-in TypeScript support, automatic documentation generation, and interoperability with npm packages.

pnpm

Leader
