imgix vs UNPKG

imgix is a visual media platform for image and video workflows, available through web and API. Connect an asset location, such as Amazon S3, Google Cloud Storage, or a web folder, and serve media through its Rendering API. URL parameters expose more than 150 image transformations, including cropping, masking, color adjustments, text overlays, and responsive resizing; images are automatically optimized and AVIF is supported. AI tools can upscale images, remove or replace backgrounds, remove objects, generate fills, create alt text, and add image tags. Video support includes adaptive HLS or DASH streaming from 360p up to 4K, capped by the source, and a stated limit of 30 minutes per video. Captions can be generated from video audio and translated into more than 100 languages. Pricing uses credits for media management, delivery, and transformations. Starter costs $25 a month and includes 100 credits per month; the free trial requires no credit card. There is no free plan.

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.
