CacheFly vs esm.sh

CacheFly is a content delivery network for streaming, game launches, ad delivery, and other high-traffic workloads. EdgeControl lets customers program caching, headers, routing, authentication, and request behavior at the edge. Dedicated Shield provides a separate cache tier intended to keep content available without competing for shared cache space. CacheFly says its network has more than 75 global points of presence and serves seven continents. Adoption includes full API access and a Terraform provider; the knowledge base documents WordPress CDN Enabler and W3 Total Cache integrations. Governance lists SSO, role-based access control, audit logs, and compliance packs, while WAF and DDoS are available on Production. Feature tiers include 10 TB per month, with additional bandwidth commits sized to a customer's traffic profile. Adoption costs $299 a month, and a free developer account is listed with 100 GB and one domain. Email support from CDN engineers is included on feature tiers. CacheFly was founded in 2002 and is headquartered in Elk Grove Village, Illinois.

esm.sh is an open-source service for importing JavaScript modules through HTTP URLs, so developers can use packages in browser apps or Deno without build tools. It serves packages from npm, JSR, GitHub and pkg.pr.new, and can transform TypeScript, TSX, Vue and Svelte files for direct imports. Modules are bundled by default; URL options let developers alter bundling, request raw content, set dependency versions or aliases, and select exports. Export selection does not work with CommonJS modules. The service supports CSS imports when a package imports CSS directly from JavaScript, and it can load modules as web workers. Build targets include es2015 through es2024, esnext, Deno, denonext and Node. A lightweight TSX script can compile and cache TSX written directly in HTML. The FAQ describes compatibility with modern browsers that support ES6 modules, including Deno. The public CDN does not support private npm packages; the project directs those users to self-hosting and provides a Docker image and deployment instructions. The project is MIT-licensed, with bug reports directed to GitHub issues.
