Secure-by-default JavaScript and TypeScript runtime from Node's original creator. Built-in TypeScript, fmt, lint, test, and Deno Deploy for edge hosting.
Deno is Ryan Dahl's redo of Node with the lessons of a decade applied. It runs TypeScript natively, sandboxes file and network access by default, and ships a full toolchain (fmt, lint, test, bench) in one binary. v2 added full npm and Node compatibility, which removed the biggest historical objection. Deno Deploy is a serverless edge runtime that pairs well with the language. A great fit for greenfield TypeScript projects that value secure-by-default and a unified toolchain.
All-in-one JavaScript runtime, bundler, test runner, and package manager. Written in Zig, drop-in compatible with Node, dramatically faster install and start times.
The original server-side JavaScript runtime. V8 under the hood, npm ecosystem, and the default backend runtime for most production deployments.
Type-safe SQL builder and ORM for TypeScript. Zero runtime overhead, honest schema migrations, bring-your-own-DB.
TypeScript-first schema validation. Define schemas once, get static types and runtime validation. The default validator for tRPC, Next.js server actions, and AI SDKs.
