Content Delivery Networks (CDNs) are the backbone of modern web infrastructure, serving web assets from edge servers located within milliseconds of end users. In 2026, CDNs have evolved beyond simple image caching into programmable edge compute platforms capable of executing serverless code, blocking sophisticated AI bot scrapers, and mitigating multi-terabit DDoS attacks.
The two undisputed leaders in this space are Cloudflare and Fastly. Here is an objective technical comparison to help you choose the right provider.
