Fastly

Fastly is the edge-cloud company people use when web pages, APIs, media, and apps need to be delivered close to users instead of from one central server. By our assessment, its best-known strength is fast content delivery with a developer-friendly platform for caching, compute at the edge, and traffic control. The trade-off is that this is infrastructure, so it asks for technical setup and real understanding of how your site or app moves data. In practice Fastly feels like a performance tool, not a consumer service: invisible when it works, very visible when a site depends on it. It sits among CDN and edge-computing providers rather than traditional hosting, and the name is tied to the United States. It is for engineering teams that care about low latency and control, not for people wanting a simple drag-and-drop website.
