# Intro to Nx

Nx is a powerful open-source build system that provides tools and techniques for enhancing developer productivity, optimizing CI performance, and maintaining code quality. Learn more about [how Nx works](/getting-started/why-nx).

You can use Nx to quickly scaffold a new standalone project or even an entire monorepo. It can be incrementally adopted and will grow with your project as it scales.

## Start a New Monorepo

Its modular architecture lets you adopt Nx for package-based monorepos in combination with NPM, Yarn or PNPM, or create a fully integrated monorepo using Nx plugins. Learn more with the tutorials below.

## Start a New Standalone Project

Nx works well not just for monorepos. Nx plugins help you scaffold new standalone projects with pre-configured tooling and modularize your codebase with local libraries.
