Deno 3.0 represents a paradigm shift in how we think about server-side JavaScript. With built-in edge deployment, native Web APIs, and a zero-config approach, it’s never been easier to build and deploy edge functions.

The new Deno Deploy 3.0 platform supports automatic region selection, persistent storage at the edge, and WebSocket connections that follow your users around the globe.

Performance benchmarks show Deno 3.0 cold starts averaging under 5ms, making it competitive with Cloudflare Workers while offering a much richer development experience.
