# 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 you as you scale.

## Start a New Monorepo

Nx has been designed from the ground up to scale well with monorepos. Its modular architecture allows you to adopt Nx for simple package-based monorepos in combination with NPM, Yarn or PNPM workspaces, or create a fully integrated and managed monorepo that leverages Nx plugins. Learn more with the tutorials below.

## Start a new Standalone Project

You can still benefit from Nx even if you don't have a monorepo. Nx plugins provide generators that help you not only scaffold a new standalone project with pre-configured tooling, but also to modularize your codebase with local libraries.
