Global, free CDN delivering npm and GitHub assets at lightning speed
A production‑grade, free CDN that instantly serves files from npm, GitHub, and other sources with multi‑CDN redundancy, version fallback, and on‑the‑fly minification.
jsDelivr is a production‑grade CDN that delivers files from npm, GitHub, WordPress plugins and custom endpoints worldwide. It is free, has no bandwidth caps, and is built to survive the traffic of the largest sites.
The service stores every requested file in permanent S3 storage, providing version fallback when a newer release removes a file. Multi‑CDN routing through Cloudflare and Fastly, powered by real‑user monitoring, selects the fastest provider per visitor and instantly fails over on outages. On‑the‑fly minification and source‑map generation give developers ready‑to‑use assets without a build step. Dedicated nodes near Chinese urban centers keep latency low for that market.
Integrate by replacing the origin URL with https://cdn.jsdelivr.net followed by the appropriate endpoint (e.g., /npm/package@1.2.3/file.js). No configuration, authentication, or server management is required—just reference the CDN URL in your HTML or build pipeline.
When teams consider jsDelivr, these hosted platforms usually appear on the same shortlist.
