CDNetworks CDN vs cdnjs

CDNetworks CDN is a paid content delivery service for websites and applications, available through web and API interfaces. Its Content Acceleration stores static content at edge points of presence so users can receive it from nearby locations. CDNetworks states that its network includes more than 3,000 PoPs across over 90 countries and regions. Dynamic Web Acceleration applies tuned TCP links and connection pooling to static and dynamic content, with support listed for HTTP 2.0, IPv6, QUIC, TLS 1.3, and WebSocket. Intelligent path selection and controls for caching, deleting, or invalidating selected edge content support delivery management. Access rules can use IP, country or region, HTTP headers, and timestamps; origins can use failover and status monitoring. A visual console covers domains, usage, certificates, and log downloads, while API references are available. Security includes basic attack mitigation and default Layer 4 DDoS mitigation for edge services. Image optimization, origin shield, video delivery, edge compute, and real-time logs are listed.

cdnjs is a free web and API service for adding JavaScript, CSS and font resources to web projects. Libraries can be referenced with script or link tags, so projects do not need a build step or npm installation. Files are delivered through Cloudflare’s global network, which cdnjs lists as having more than 330 edge locations. HTTP/3, HTTP/2 and QUIC are supported, along with Brotli and GZIP compression. cdnjs is HSTS preloaded and supplies Subresource Integrity hashes for script and link tags. Its community-curated catalog lists 4,616 libraries. After approval, automation checks npm or GitHub for new versions and manages minification, compression, hash generation and publishing. The service does not pull arbitrary libraries on demand. An unauthenticated API is available at https://api.cdnjs.com. The listed cdnjs plan costs nothing.
