About
Skypack is a CDN for optimized npm packages that serves JavaScript modules directly from URLs such as https://cdn.skypack.dev/package-name. It preoptimizes packages for browser use and supports package versions, scoped packages, package exports, minified output, TypeScript declarations via ?dts, and CSS assets.
The service includes HTTP/2 and HTTP/3 support, global edge caching, universal caching across websites, automatic conversion of older Node packages to ES modules, JS minification, Brotli and gzip compression, and automatic polyfills for older browsers that support ES modules. The page states that the basic CDN is free to use for personal and commercial purposes, but no specific free-usage allowance is listed.

Free Tier Value
This free tier is a permanently free, publicly accessible CDN with no stated usage cap, so there isn’t a defensible monthly dollar estimate to anchor against a paid plan. The page explicitly says it is free to use for personal and commercial purposes, forever, and there’s no sign-up or credit card friction for basic use.
