Monorepos have become the standard for serious JavaScript/TypeScript projects. Google, Meta, Microsoft, and most well-funded startups use them. But choosing between Turborepo, Nx, and pnpm workspaces can be overwhelming.

The right choice depends on your team size, project complexity, and how much tooling you want.

Monorepo Tooling Modern monorepo tools make managing large codebases practical

Why Monorepos

Before comparing tools, understand why monorepos matter:

Benefit Description
Shared code Reuse components, utilities, and types across projects
Atomic changes Update library and consumers in one commit
Consistent tooling Same linting, testing, and build configuration everywhere
Simplified dependencies One version of each package across all projects
Better refactoring IDE finds all usages across the entire codebase

The cost: you need tooling to manage complexity at scale.

The Contenders

pnpm Workspaces

The minimal approach — just workspace support with fast package management.

Turborepo

Vercel's build system focused on caching and task running. Minimal configuration, maximum speed.

Nx

The full-featured option with generators, plugins, and deep framework integration.

Quick Comparison

Feature pnpm Workspaces Turborepo Nx
Package management Yes No (needs pnpm/npm/yarn) Yes (wraps npm/pnpm/yarn)
Task caching No Yes (local + remote) Yes (local + remote)
Task orchestration Basic Yes Yes
Code generation No No Yes (generators)
Dependency graph No Yes Yes (visualized)
Affected commands No Yes Yes
Framework plugins No No Many (Next.js, React, Node)
Learning curve Low Low Medium-High
Configuration Minimal Minimal Extensive

pnpm Workspaces: The Minimalist Choice

pnpm workspaces provide basic monorepo support without additional tooling.

Setup

# pnpm-workspace.yaml
packages:
  - 'apps/*'
  - 'packages/*'
// package.json
{
  "name": "my-monorepo",
  "scripts": {
    "build": "pnpm -r build",
    "test": "pnpm -r test",
    "lint": "pnpm -r lint"
  }
}

That's it. pnpm handles symlinking, hoisting, and workspace dependencies.

When to Use pnpm Workspaces Alone

Good for:

  • Small teams (1-5 developers)
  • 2-5 packages
  • Simple build requirements
  • Teams that want minimal tooling
  • Projects where build times are already fast

Example structure:

my-monorepo/
├── apps/
│   └── web/           # Next.js app
├── packages/
│   ├── ui/            # Shared components
│   └── utils/         # Shared utilities
├── pnpm-workspace.yaml
└── package.json

Limitations

  • No caching — every pnpm -r build rebuilds everything
  • No affected detection — cannot run only what changed
  • No remote caching — CI always starts fresh
  • Manual task orchestration — you handle dependencies

For small projects, these limitations do not matter. For larger ones, they become painful.

Turborepo: Speed Without Complexity

Turborepo adds intelligent caching and task orchestration with minimal configuration.

Setup

npx create-turbo@latest
# or add to existing pnpm workspace
pnpm add turbo -D -w
// turbo.json
{
  "$schema": "https://turbo.build/schema.json",
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": ["dist/**", ".next/**"]
    },
    "test": {
      "dependsOn": ["build"]
    },
    "lint": {},
    "dev": {
      "cache": false,
      "persistent": true
    }
  }
}

Key Features

1. Intelligent Caching

Turborepo hashes inputs and caches outputs:

$ turbo build
• Packages in scope: web, ui, utils
• Running build in 3 packages
web:build: cache hit, replaying output
ui:build: cache hit, replaying output
utils:build: cache hit, replaying output

 Tasks:    3 successful, 3 total
Cached:    3 cached, 3 total
  Time:    156ms >>> FULL TURBO

Second build: 156ms instead of 45 seconds.

2. Remote Caching

Share cache across team and CI:

# Enable remote caching
npx turbo login
npx turbo link

# Now cache is shared
# Developer A builds → cache uploaded
# Developer B pulls → instant cache hit
# CI runs → instant cache hit

3. Parallel Execution

Turborepo runs independent tasks in parallel while respecting dependencies:

Task Graph Execution
├── utils:build (runs first, no deps)
├── ui:build (waits for utils)
└── web:build (waits for ui)
    ├── web:lint (runs parallel with build)
    └── web:test (waits for build)

When to Use Turborepo

Good for:

  • Teams wanting fast builds without complexity
  • Projects already using pnpm/npm/yarn workspaces
  • Next.js and Vercel-centric projects
  • Teams that value simplicity over features
  • 5-50 packages

Turborepo philosophy: Do one thing well (caching and task running).

Nx: The Full Platform

Nx provides a complete monorepo platform with generators, plugins, and deep IDE integration.

Setup

npx create-nx-workspace@latest my-workspace
# or add to existing project
npx nx@latest init
// nx.json
{
  "targetDefaults": {
    "build": {
      "dependsOn": ["^build"],
      "cache": true
    },
    "test": {
      "cache": true
    }
  },
  "defaultBase": "main"
}

Key Features

1. Generators

Scaffold consistent code across the monorepo:

# Generate a new React library
nx g @nx/react:lib ui-components

# Generate a new Next.js app
nx g @nx/next:app dashboard

# Generate a component
nx g @nx/react:component Button --project=ui-components

Generators ensure consistent patterns, file structures, and configurations.

2. Plugins

Deep integration with frameworks:

Plugin Provides
@nx/next Next.js support, SSR optimization
@nx/react React component generators
@nx/node Node.js/Express support
@nx/nest NestJS integration
@nx/storybook Storybook setup and testing
@nx/cypress E2E testing integration

3. Dependency Graph Visualization

nx graph
# Opens interactive visualization of project dependencies

See which projects depend on which, helping understand impact of changes.

4. Affected Commands

Run tasks only on what changed:

# Only build affected projects
nx affected -t build

# Only test affected projects
nx affected -t test

# Show what would be affected
nx affected --graph

This is critical for large monorepos where running everything takes too long.

5. Module Federation

Built-in support for micro-frontends:

// webpack config
module.exports = withModuleFederation({
  name: 'shell',
  remotes: ['dashboard', 'settings']
})

When to Use Nx

Good for:

  • Large teams (10+ developers)
  • Many packages (20+)
  • Enterprise environments wanting standardization
  • Teams that value conventions and generators
  • Projects needing module federation
  • Organizations wanting enforced architecture boundaries

Nx philosophy: Provide everything needed for large-scale development.

Head-to-Head Comparison

Build Speed (Cold Cache)

Both Turborepo and Nx have similar performance — the tools themselves are not the bottleneck.

Build Speed (Warm Cache)

Both achieve near-instant builds with cache hits. Remote caching is available in both.

Configuration Effort

Scenario pnpm Turborepo Nx
Basic setup 5 min 15 min 30 min
Add new package 2 min 2 min 5 min (or use generator)
Add caching N/A Built-in Built-in
Remote caching N/A Easy (Vercel) Easy (Nx Cloud)
Custom generators N/A Manual Built-in

Ecosystem Lock-in

pnpm: No lock-in. It's just a package manager.

Turborepo: Minimal lock-in. turbo.json is simple. Easy to remove.

Nx: More lock-in. Plugins, generators, and conventions are Nx-specific. Migration away is more work.

Decision Framework

Use pnpm Workspaces If

  • You have 2-5 packages
  • Build times are under 2 minutes
  • You want zero additional tooling
  • Your team is small (1-5 developers)

Use Turborepo If

  • Build times matter (over 5 minutes)
  • You want remote caching without complexity
  • You prefer minimal configuration
  • You are using Vercel for deployments
  • You have 5-30 packages

Use Nx If

  • You have a large team (10+ developers)
  • You want enforced conventions and generators
  • You need module federation
  • You have complex dependency graphs
  • You value IDE integration and visualization
  • You have 20+ packages

Practical Recommendation

For most teams starting a new project:

Start with Turborepo + pnpm.

pnpm dlx create-turbo@latest

This gives you:

  • Fast, reliable package management (pnpm)
  • Intelligent caching (Turborepo)
  • Minimal configuration
  • Easy remote caching

If you outgrow it — if you need generators, module federation, or stricter architecture boundaries — Nx is there. But many teams never need to make that switch.

The best monorepo tool is the one your team will actually use effectively. Start simple, add complexity only when needed.
