What problem does it solve?

Netlify Edge Functions enable developers to run code at the network edge using the Deno runtime, enabling low-latency middleware, geolocation decisions, request/response manipulation, and edge-based authentication and experimentation.

Core Features & Use Cases

• Edge middleware patterns with context.next() for seamless request processing and redirection.
• Geolocation-based routing, redirects, and personalization at the edge.
• Lightweight authentication checks and access control performed close to users.
• A/B testing and feature flags implemented at the edge for faster experiments.
• Clear guidance on when to choose edge vs serverless for latency-sensitive workloads.

Quick Start

Create a simple edge function under netlify/edge-functions and implement a middleware using context.next() to gate access.
