Deno: A Runtime for the Edge

Discover Deno's features, security model, and its suitability for building robust edge applications.

Meet Deno: A Modern Runtime

Deno is a modern, secure runtime for JavaScript and TypeScript from Ryan Dahl — Node's creator — built to fix Node's pain points. A natural fit for the edge.

Security First: Permission Model

Deno is secure by default: scripts can't touch your files, network, or env vars without explicit permission. That sandboxed control is perfect for edge functions.
