Turborepo vs Nx vs Moon: Monorepo Tools Compared 2026

Benchmarks show Nx is 7x faster than Turborepo in large monorepos with 50+ packages. Turborepo — now rewritten from Go to Rust — is closing that gap and remains the default for teams that want a simple, fast task runner without the full platform. Moon manages its own toolchain versions so every developer runs the same Node.js, pnpm, and Bun version without manual coordination. These tools solve the same core problem — building monorepos efficiently — with meaningfully different philosophies.

TL;DR

Turborepo for the fastest onramp to monorepo task caching — minimal config, great defaults, excellent for JavaScript/TypeScript workspaces. Nx when you need a full monorepo platform: code generators, module boundary enforcement, AI-powered CI optimization, and cross-language support. Moon when toolchain consistency (exact Node.js versions, same package manager version) matters as much as task orchestration. For most JS/TS monorepos, Turborepo is the pragmatic starting point.

Key Takeaways

• Turborepo: 3.8M weekly npm downloads, Vercel-maintained, rewritten from Go to Rust for performance
• Nx: 3.6M weekly downloads, Nrwl-maintained, "Build Intelligence Platform" with AI features in 2025
• Moon: 50K weekly downloads, written in Rust, polyglot (Node, Go, Python, Rust projects)
• Turborepo: Simple config, package.json scripts orchestration + remote caching
• Nx: Fine-grained affected analysis, code generators, module boundaries, project graph visualization
• Moon: Toolchain management (exact runtime versions), task inheritance, polyglot support
• All three: Task hashing/caching, parallel task execution, dependency graph ordering

Why Monorepo Tooling?

Without specialized tooling, monorepos suffer from:

# Running builds across 30 packages:
npm run build --workspace=*  # Runs all 30, even unchanged ones
# Every CI run rebuilds everything — slow and wasteful

# With Turborepo/Nx/Moon:
turbo build  # Only rebuilds changed packages + dependents
# Unchanged packages: restored from cache instantly

The core value: task caching. Once a package's files haven't changed, the build output is restored from cache (local or remote) in milliseconds.

Turborepo

Package: turbo Weekly downloads: 3.8M GitHub stars: 27K Creator: Vercel (acquired from Jared Palmer, 2021) Written in: Rust (rewritten from Go, 2024)

Turborepo describes itself as a "package.json scripts orchestrator with a caching layer." That's accurate — and for most teams, that's exactly what they need.

Installation

npx create-turbo@latest
# Or add to existing workspace:
npm install -D turbo

Configuration

// turbo.json
{
  "$schema": "https://turbo.build/schema.json",
  "tasks": {
    "build": {
      "dependsOn": ["^build"],  // Run after all dependencies' build tasks
      "outputs": ["dist/**", ".next/**"]
    },
    "test": {
      "dependsOn": ["build"],
      "inputs": ["src/**", "tests/**"]
    },
    "lint": {
      "outputs": []
    },
    "dev": {
      "cache": false,           // Never cache dev task
      "persistent": true        // Long-running process
    }
  }
}

Running Tasks

# Build everything (only rebuilds changed packages)
turbo build

# Build specific package and its dependencies
turbo build --filter=web

# Run affected only (since last commit)
turbo build --filter=[HEAD^1]

# Run in parallel
turbo lint test  # Both run simultaneously, respecting deps

Remote Caching

# Link to Vercel Remote Cache
npx turbo login
npx turbo link

# Now CI shares cache with local builds:
turbo build  # CI hits local dev cache → instant "builds"

Turborepo's remote cache with Vercel is free for personal use and included in team plans. Alternatives: Turborepo supports custom remote caches (self-hosted).

Turborepo Strengths

• Minimal config: turbo.json is ~20 lines for a basic setup
• Fast: Rust-based core with excellent parallelism
• Vercel integration: Remote caching just works with Vercel
• Ecosystem: Best documentation, most community examples

Turborepo Limitations

• Less powerful affected analysis than Nx (coarser granularity)
• No code generators (you bring your own plop/hygen/etc.)
• No module boundary enforcement
• No built-in toolchain management (no version pinning for Node.js, etc.)

Nx

Package: nx, @nx/workspace, various plugin packages Weekly downloads: 3.6M (nx package alone) GitHub stars: 24K Creator: Nrwl (now Nx Inc.) Written in: TypeScript (core migrating to Rust, 2025)

Nx is a full monorepo platform, not just a task runner. It has generators, project graph visualization, module boundary linting, and in 2025 added AI-powered CI optimization ("Build Intelligence Platform").

Installation

npx create-nx-workspace@latest my-workspace
# Or add to existing workspace:
npx nx@latest init

Configuration

// nx.json
{
  "targetDefaults": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": ["{projectRoot}/dist"],
      "cache": true
    },
    "test": {
      "inputs": ["default", "^production"],
      "cache": true
    }
  },
  "namedInputs": {
    "default": ["{projectRoot}/**/*", "sharedGlobals"],
    "production": ["default", "!{projectRoot}/**/*.spec.ts"],
    "sharedGlobals": ["{workspaceRoot}/tsconfig.base.json"]
  }
}

Fine-Grained Affected Analysis

Nx's most powerful feature — it knows exactly which tests need to run:

# Nx analyzes the project graph to find what's affected
nx affected --target=test

# More accurate than Turborepo's file-hash approach:
# If you change a utility function, Nx knows which specific tests import it
# Turborepo would rebuild/retest the entire package

Code Generators

# Generate a new React library
nx generate @nx/react:library ui-components \
  --directory=packages/ui-components \
  --style=css

# Generate a new Next.js app
nx generate @nx/next:application dashboard \
  --directory=apps/dashboard

# Generate a new feature component
nx generate @nx/react:component Button \
  --project=ui-components

This scaffolding creates properly configured projects with correct tsconfig, build config, and test setup automatically.

Module Boundary Enforcement

// .eslintrc.json
{
  "rules": {
    "@nx/enforce-module-boundaries": ["error", {
      "depConstraints": [
        {
          "sourceTag": "scope:app",
          "onlyDependOnLibsWithTags": ["scope:feature", "scope:ui", "scope:util"]
        },
        {
          "sourceTag": "scope:feature",
          "onlyDependOnLibsWithTags": ["scope:ui", "scope:util"]
        },
        {
          "sourceTag": "scope:ui",
          "onlyDependOnLibsWithTags": ["scope:util"]
        }
      ]
    }]
  }
}

This prevents circular dependencies and enforces architectural rules at lint time — before code reaches CI.

Nx Strengths

• Most powerful affected analysis (7x faster than Turborepo in 50+ package repos)
• Code generators for consistent scaffolding
• Module boundary enforcement
• Cross-language support (Go, Python, Java with plugins)
• AI-powered CI (Nx Cloud identifies flaky tests, optimizes task distribution)
• Distributed task execution (parallelize across multiple CI agents)

Nx Limitations

• Steeper learning curve (generators, configuration, concepts)
• More configuration than Turborepo for basic setups
• Plugin ecosystem adds significant complexity
• Not ideal for simple workspaces where Turborepo would suffice

Moon

Package: @moonrepo/cli Weekly downloads: 50K GitHub stars: 3.5K Creator: Miles Johnson / moonrepo team Written in: Rust

Moon is a task runner and repository management tool focused on toolchain consistency and polyglot support. Unlike Turborepo and Nx which are JavaScript-first, Moon manages Node.js, Python, Go, and Rust projects in the same repository.

Installation

# Via installer (not npm — manages its own binary)
curl -fsSL https://moonrepo.dev/install/moon.sh | bash

# Or via proto (Moon's toolchain manager):
proto install moon

Workspace Configuration

# .moon/workspace.yml
node:
  version: '22.13.0'       # Exact version for ALL developers
  packageManager: 'pnpm'
  packageManagerVersion: '10.4.0'  # Exact pnpm version too

vcs:
  manager: 'git'
  defaultBranch: 'main'

Every developer and CI machine uses exactly Node.js 22.13.0 and pnpm 10.4.0 — Moon installs them automatically if not present.

Task Definition

# packages/ui/moon.yml
tasks:
  build:
    command: 'pnpm build'
    inputs:
      - 'src/**/*'
      - 'tsconfig.json'
    outputs:
      - 'dist/**/*'

  test:
    command: 'pnpm test'
    inputs:
      - 'src/**/*'
      - 'tests/**/*'

Task Inheritance

# .moon/tasks.yml (inherited by all projects)
tasks:
  lint:
    command: 'eslint .'
    inputs:
      - '@group(sources)'  # Predefined group

  typecheck:
    command: 'tsc --noEmit'
    inputs:
      - '@group(sources)'

All packages inherit lint and typecheck tasks without repeating them in each package's moon.yml.

Moon Strengths

• Toolchain management: exact runtime versions for all developers
• Task inheritance: define tasks once, inherit everywhere
• Polyglot: Node.js, Go, Python, Rust in one monorepo
• Rust performance: fast graph analysis and task execution
• Strong reproducibility across environments

Moon Limitations

• Smaller community than Turborepo/Nx
• Less ecosystem documentation and examples
• Not as feature-rich for JavaScript-specific workflows (generators, module boundaries)
• Learning curve from YAML-based config
