Fastly vs Akamai

Fastly and Akamai are both premium CDN platforms, but they differ in philosophy and target audience. Fastly is an engineering-focused CDN built for teams that want maximum control and speed. Akamai is the enterprise CDN with the world's largest network and the broadest security portfolio.

Network Scale

Akamai's 4,200+ edge locations dwarf Fastly's 90+ PoPs. Akamai has servers embedded inside ISP networks and last-mile infrastructure globally, giving it the best possible end-user proximity. Fastly compensates with strategically located, well-connected PoPs that serve most traffic efficiently, but its reach in developing regions is more limited.

Cache Purge: Fastly's Edge

Fastly's 150ms global cache purge is its defining feature. For a news organization publishing breaking stories, an e-commerce site updating prices, or a real-time sports platform, the ability to purge and replace cached content instantly is a competitive advantage. Akamai's cache invalidation takes seconds to minutes — acceptable for most use cases but not for latency-critical content updates.

Developer Experience

Fastly provides VCL (Varnish Configuration Language) for cache configuration, giving developers code-level control over caching logic. Compute@Edge uses WebAssembly for edge compute, supporting Rust, Go, and JavaScript. Fastly's developer tools, local testing, and real-time stats dashboard are best-in-class.

Akamai's Property Manager is powerful but complex, with a UI-driven rule system that can be harder for developers to iterate on. EdgeWorkers provides JavaScript-based edge compute but is less flexible than Wasm-based alternatives.
