## Summary

Nx is an open-source monorepo build system and developer platform that speeds up builds with intelligent caching, dependency graph analysis, and distributed task execution.

## Company Overview

Nx is a developer tooling company and open-source project originally created at Nrwl in 2018 that provides a smart build system and workspace management tools for monorepo development. The platform analyzes project dependency graphs to determine which parts of a codebase are affected by any given change, then runs only the necessary build, test, and lint tasks rather than rebuilding everything. Nx Replay provides distributed remote caching that allows entire teams and CI pipelines to share computed results, dramatically reducing build times in large codebases. Nx Cloud extends this with distributed task execution that splits work across multiple machines automatically. The platform supports JavaScript, TypeScript, React, Angular, Node.js, Go, and other languages and frameworks, making it framework-agnostic. Nx has been adopted by thousands of organizations including major technology companies managing large multi-team codebases. The company raised $8.6M and has built a robust open-source community with millions of monthly downloads. Nx competes with Turborepo and Bazel for the monorepo tooling market while focusing on developer experience and deep framework integration.

## Frequently Asked Questions

### What is Nx?
Nx is an open-source monorepo build system that uses dependency graph analysis and distributed caching to run only the build and test tasks affected by code changes, dramatically speeding up development workflows in large codebases.

### How does Nx speed up CI builds?
Nx Replay provides distributed remote caching that allows CI pipelines and developers to share computed task results, so if a task has already run with the same inputs, the cached output is used instead of re-running the computation.

### What languages does Nx support?
Nx supports JavaScript, TypeScript, React, Angular, Next.js, Node.js, Go, and other languages and frameworks, and is designed to be framework-agnostic so teams with diverse tech stacks can use it in a single monorepo.

### What is Nx Cloud and how is it different from open-source Nx?
Open-source Nx provides local task caching and monorepo tooling for free. Nx Cloud adds distributed remote caching shared across the entire team and CI, distributed task execution across multiple machines, and workspace analytics dashboards — accelerating CI builds significantly for larger engineering teams.

### Is Nx only for JavaScript and TypeScript projects?
No. While Nx started as a JavaScript monorepo tool, it now supports Go, Rust, Python, Java, and .NET through plugins, making it suitable for polyglot monorepos where multiple languages or frameworks coexist in a single repository.

### How does Nx handle affected builds in CI?
Nx analyzes the project dependency graph and compares it against changed files in a pull request to determine which projects are affected. CI pipelines run build, test, and lint tasks only for affected projects, reducing CI time proportionally to how isolated the change is.

### Can Nx be adopted incrementally in an existing monorepo?
Yes. Nx can be added to an existing monorepo without migrating all projects at once. Teams start with Nx's caching and affected detection capabilities on existing projects, then gradually add Nx generators and plugins for new projects as the team becomes comfortable.

### Does Nx integrate with popular CI systems?
Yes. Nx integrates with GitHub Actions, GitLab CI, CircleCI, Jenkins, Azure DevOps, and other major CI systems, with official documentation and CI presets that configure affected task detection and remote caching automatically.
