UNPKG vs Uploadcare

UNPKG is a free CDN for files published on npm, with package files addressed by URLs containing a package name, version, and file path. A URL can specify an exact version, an npm dist-tag, or a semver range; when the version is omitted, UNPKG resolves the latest tag. If the file path is omitted, it resolves the package's default entry point, including package exports and subpaths. For browser apps, import maps can load JavaScript modules without a build step. The esm.unpkg.com service can transform TypeScript and JSX, bundle package internals, and rewrite dependency imports to pinned UNPKG URLs for modern browsers. Module URLs support options including targets, export conditions, aliases, minification, source maps, and raw files. Adding ?meta to a package root or subdirectory returns JSON metadata with file paths, sizes, types, and subresource integrity values. UNPKG says npm files become available within minutes of publication. Its files run through Cloudflare's global edge network and Workers, and versioned URLs are cached. The project describes itself as open source and says it is not affiliated with or supported by npm.

Uploadcare is a file-handling platform for websites and mobile apps, covering uploads, storage, image processing and delivery through a CDN. Its API accepts direct, multipart and URL uploads, and the uploader can also take files from local storage, a webcam, URLs and listed cloud services. Image tools include URL-based transformations, automatic optimization, responsive images and format selection. Paid plans add asynchronous video processing and document conversion. Uploadcare lists integrations for JavaScript, React, Angular, Vue, Webflow, Framer and WordPress, plus Zapier and Make; Swift and Kotlin SDKs and iOS and Android upload widgets are also available. Its stated security measures include malware scanning, TLS 1.2+ in transit and AES-256 encryption at rest. A free plan allows 1 GB storage, 5 GB monthly traffic and 1,000 operations per month, with a 500 MB file limit. Reaching its usage limits suspends service until the next month. Pro costs $66/mo (annual).
