jsDelivr

jsDelivr is a globally distributed content delivery network (CDN) specifically designed for serving open-source web development resources. Founded in 2012 by Prospect One, it has grown to become one of the most popular free CDN services in the world, handling billions of requests daily. The platform automatically fetches files from GitHub, npm, and WordPress plugin directories, providing developers with reliable, high-performance access to libraries like jQuery, Bootstrap, React, Vue.js, Font Awesome, and thousands of other packages. Unlike commercial CDNs, jsDelivr operates as a free public service with no usage limits or registration requirements, making it particularly valuable for small projects, educational resources, and developers in regions with limited infrastructure. The service uses multiple CDN providers including Cloudflare, Fastly, and G-Core Labs to ensure maximum uptime and global coverage. Its infrastructure is optimized for web performance with features like HTTP/2, Brotli compression, and intelligent failover routing. The domain jsdelivr.net serves as the primary endpoint for all CDN requests, with subdomains used for specific package sources. As a critical piece of modern web infrastructure, jsDelivr significantly reduces latency for end-users while offloading traffic from origin servers, contributing to faster page loads and better user experiences worldwide.
