Edge Functions are now available in Public Beta. They allow developers to deliver content to your site with speed and personalization, by enabling them to serve the exact end-user experience they're imagining, every time. Edge Functions have instant cold boots, support streaming, and are deployed globally by default.

To get started with Edge Functions, create a _middleware.js file in the pages/ directory for Next.js 12+ or on the root of any Vercel project. Middleware enables Edge authentication, bot protection, feature flags, A/B testing, server-side analytics, logging, and more.

Read about deploying Edge Functions in the documentation, and check out the examples.
