Azion Content Delivery vs UNPKG

Azion Content Delivery accelerates content using distributed infrastructure, caching and serverless functions, with stated delivery latency below 30 ms. It includes image optimization, Origin Shield, a web application firewall and DDoS protection. Caching controls cover browser and edge expiration, large files, cookie or query-string behavior, tiered cache and real-time purge; connectors can link applications to HTTP origins or Object Storage. Azion says its infrastructure can provide up to 10× higher performance than traditional solutions and reduce cloud costs by up to 80%, which are stated potential outcomes. The Hobby plan costs nothing and includes global infrastructure, functions, storage, databases, image optimization and DDoS protection, subject to usage and resource limits. Pro costs $25 a month, billed monthly, and can be cancelled anytime. Enterprise pricing is custom. Annual billing requires a 12-month commitment and full upfront payment. All plans include Developer Support; paid tiers offer additional support options.

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.
