Edge Functions connect the Netlify platform and workflow with an open runtime standard at the network edge. This enables you to build fast, personalized web experiences with an ecosystem of development tools.
All this dynamic processing happens in a secure runtime based on Deno directly from the worldwide network edge location closest to each user. With Netlify, your edge functions are version-controlled, built, and deployed along with the rest of your Netlify site. This eliminates overhead and brings the power of Deploy Previews and rollbacks to your edge functions.
