Faster page loads

Poor web and mobile performance can negatively impact customer conversion and retention rates, SEO, and advertising revenue. Fastly’s edge cloud platform accelerates your web and mobile applications while world-class Dynamic Site Acceleration (DSA) speeds up content delivery. We allow you to keep more in cache for longer and retrieve it quicker for faster page load times. Unique features like Origin Shield and Request Collapsing help ensure a seamless user experience even when you need to clear cache.

Caching and purging

Much of today’s content is neither static nor fully dynamic. News headlines, stock prices, weather, and inventory remain static for some period of time and then change unpredictably. We call this type of content “event-driven,” and Fastly’s edge cloud can cache it because it can be purged instantly. Our Instant Purge feature allows you to cache and invalidate content almost as soon as it’s updated on your origin — within 150 milliseconds or less across our global network. This is considerably faster than other CDNs.

Image optimization

Fastly offers a real-time image manipulation and delivery service. Built on our powerful edge cloud platform, Fastly Image Optimizer allows you to transform and serve images at the edge, closer to your users. We eliminate offline image pre-processing tasks and drastically speed up delivery. You get pixel-perfect, bandwidth-efficient images optimized for different user devices and web browsers. Caching multiple images at the edge also reduces traffic to origin, resulting in significant cost savings.
