unpkg is a global content delivery network that serves any file from any npm package via simple URLs like unpkg.com/package@version/file. The repository contains the production source, including Cloudflare Workers for the website, package browser, and ESM serving, plus a Bun-based file server backend.

Use cases

• load npm package files directly in the browser via script tags
• serve browser-ready ESM builds of npm packages
• browse and explore files inside npm packages
• pin dependencies to exact versions or semver ranges in a URL
• self-host an npm file CDN on Cloudflare Workers and Fly.io

When to choose

• you need to load a specific file from any npm package over a CDN without installing it
• you want browser-ready ESM modules, import maps, or inline TS/TSX transforms from npm packages
• you want to browse package contents and file listings online
• you want to run your own npm file CDN infrastructure

When to avoid

• you need a full package manager or dependency resolution for local development
• you require guaranteed uptime SLAs for production-critical assets without a fallback
• you need private npm registry packages
