Deno

Deno is a modern, secure runtime for JavaScript and TypeScript, created by the original creator of Node.js to address its shortcomings with a cleaner, more secure, and more capable foundation. It runs JavaScript and TypeScript with security and developer experience as first principles: code runs in a secure sandbox by default, TypeScript works out of the box without configuration, and a comprehensive set of built-in tools removes the need for the sprawling configuration and dependencies that plague traditional JavaScript development. For developers who want a fresh, modern alternative to Node, Deno offers a thoughtfully designed runtime.

The runtime emphasizes security by running code without file, network, or environment access unless explicitly granted, reducing the risk from untrusted dependencies. It supports TypeScript natively, includes built-in tooling like a formatter, linter, test runner, and bundler so you don't have to assemble them yourself, and embraces modern web standards. Beyond the runtime, Deno offers a fast edge deployment platform for running JavaScript and TypeScript globally with low latency, making it easy to deploy modern apps and functions close to users. This combination of a secure, batteries-included runtime and a modern deployment platform reflects Deno's goal of a better, simpler JavaScript ecosystem.

Deno is used by developers who want a modern, secure, and convenient runtime for JavaScript and TypeScript, and by teams deploying edge functions and applications. The value is a cleaner, safer, more productive foundation: secure-by-default execution, native TypeScript, and built-in tooling remove much of the friction and risk of traditional JavaScript development, while the edge platform makes global deployment easy. For developers frustrated by Node's accumulated complexity and security concerns, Deno offers a compelling, modern alternative built with the benefit of hindsight. As the JavaScript ecosystem evolves, Deno represents a thoughtful reimagining of the runtime that has won a growing community.
