What jsDelivr is
jsDelivr is a free CDN for open source files from GitHub and npm. It is optimized for JavaScript and ESM delivery and supports all web formats. The service has no bandwidth limits or premium features, and its Free CDN plan is listed as free. Its network combines Cloudflare, Fastly, Bunny, GCore, and custom servers where coverage is limited, across 540 edge locations. A load balancer selects providers using recent performance and availability data, and can remove degraded providers from regional traffic. Failover includes two independent DNS providers, CDN health monitoring, and multiple origin data centers. Package tools include on-demand file combining and minification, source map support, and version aliasing. The API provides package versions, tags, files, entry-point suggestions, and download and network-wide usage statistics. Its ESM delivery supports modern browsers, Node.js, and Deno, with HTTP/3, Brotli compression, caching, and dependency preloading. The project identifies security as an area of focus and provides formal terms and a privacy policy. It describes the CDN as suitable for production sites, including those with very large traffic volumes.
