A server-side JavaScript runtime built on V8 that lets one language run your whole stack.
Official siteNode.js runs JavaScript outside the browser, on the server, using Chrome's V8 engine. Its event-driven, non-blocking I/O model makes it well suited to network-bound work — APIs, real-time services, and glue between systems — where a request spends most of its time waiting rather than computing.
Because it is JavaScript, Node lets a team share language, types and tooling between frontend and backend. Its package ecosystem (npm) is the largest of any language, which is both its greatest strength and a supply-chain responsibility.
Node.js is a runtime, not a framework. It provides the event loop, file/network access and a module system; you add a framework such as Express or NestJS on top to structure an application.
Node is our default backend runtime for REST/GraphQL APIs and backend-for-frontend layers, especially with TypeScript and NestJS. It keeps the whole stack in one language, which speeds up small-to-mid teams considerably.
Node is not the tool for CPU-bound number-crunching — a single busy loop blocks everything, so heavy compute belongs in workers or a different language like Rust. The npm ecosystem is huge but demands care around dependencies and security.
Our core API runs on NestJS (a TypeScript framework on Node), and our AI/agent work uses TypeScript and Node for orchestration. When a hot path needs raw throughput — like our crawler — we drop to Rust instead.
A typed superset of JavaScript that catches whole classes of bugs before your code ever runs.
A systems language that delivers C-level performance with memory safety guaranteed at compile time.
A query language for APIs that lets clients ask for exactly the data they need — no more, no less.
Common questions
Straight answers on how this fits your marketing and build.
No. Node.js is a runtime that executes JavaScript on the server. The language is JavaScript (or TypeScript compiled to it); Node provides the environment and I/O APIs to run it outside a browser.
