Edge computing runs application code in many locations close to where users are, instead of in one central server. For web applications it means lower latency and shorter round trips, because the response is generated near the visitor.
The practical effect is speed and resilience: a page or API responds from the nearest location, and there is no single region whose outage takes everything down. The trade-off is that edge runtimes are lightweight, so workloads are designed to fit them rather than lifting a traditional server unchanged.
Cloudflare Workers is the edge platform we build on; the same model underpins fast sites, global APIs, and AI features that answer quickly regardless of where the user is.
