The open-source JavaScript, TypeScript, and WebAssembly runtime for the modern web.
The open-source JavaScript, TypeScript, and WebAssembly runtime for the modern web.
Deno is a modern runtime environment built on V8, Rust, and Tokio, designed to provide a secure and efficient platform for executing JavaScript, TypeScript, and WebAssembly code. It offers a built-in toolchain, including a linter, test runner, and code formatter, eliminating the need for external dependencies. Deno emphasizes security by default, requiring explicit permissions for file system, network, and environment access. It seamlessly integrates with web standard APIs and supports Node.js compatibility through npm and import maps. The Deno Deploy platform allows for serverless deployment with features like OpenTelemetry, Deno KV, and a command-line interface. Deno Sandbox enables secure execution of untrusted code in isolated Linux microVMs, ideal for AI agents and dynamic workloads.
