Why I Chose Turborepo Over Nx: Monorepo Performance Without the Complexity

I spent 4 hours trying to configure Nx for my 10-package monorepo. Then I tried Turborepo and had it working in 15 minutes.

The difference? Turborepo builds ran in 2.8 seconds. Nx took 8.3 seconds. Same codebase, same machine, 3x performance gap.

But here's what really sold me: Turborepo's config was 20 lines. My Nx config? Over 200 lines and I still wasn't sure what half of it did.

If you're building a monorepo and want speed without the complexity tax, keep reading. I'll show you real benchmarks, configuration examples, and exactly when Nx might be the better choice (hint: probably not as often as you think).

🎯 The Problem

The Context

I was building a full-stack monorepo with:

• 3 applications: Portfolio site (Next.js), web app, and future backend
• 2 shared packages: UI design system, CLI tool
• 1 config package: Shared TypeScript configs
• Team size: Solo (now), 2-5 (future)
• Timeline: 90-day transformation project
• Constraints: Need fast iteration, minimal configuration overhead

The Challenge

Running builds manually across packages was painful:

• 🐌 Sequential builds: 5+ minutes to build everything
• 🔄 No caching: Rebuilding unchanged packages
• 🤝 Dependency coordination: Manual ordering of package builds
• 🔥 Dev experience: Slow feedback loops killing productivity

Why This Decision Mattered

• ⏱️ Developer productivity: 50+ builds per day
• 💰 CI/CD costs: Faster builds = cheaper pipelines
• 🔄 Migration difficulty: Switching later = 2-3 days work
• 📈 Scalability: Need to support 10+ packages eventually

✅ Evaluation Criteria

Must-Have Requirements

1. Fast build caching - Must cache unchanged packages
2. Parallel execution - Run independent tasks simultaneously
3. Simple configuration - Less than 30 min setup time
4. TypeScript support - First-class TS integration
5. pnpm workspaces - Works with my package manager

Nice-to-Have Features

• Remote caching for team collaboration
• Integration with Vercel (deployment platform)
• Active community and documentation
• Plugin ecosystem for extensibility

Deal Breakers

• ❌ Configuration files over 100 lines
• ❌ Learning curve over 2 days
• ❌ Poor pnpm support
• ❌ Requires major architectural changes

What It Is

Turborepo is a high-performance build system for JavaScript/TypeScript monorepos, built in Go for maximum speed. Acquired by Vercel in 2021, it focuses on doing one thing exceptionally well: making builds fast.

How It Works

# Install
pnpm add -D turbo

# Create turbo.json (only file needed!)
{
  "$schema": "https://turbo.build/schema.json",
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": ["dist/**", ".next/**"]
    },
    "dev": {
      "cache": false,
      "persistent": true
    }
  }
}

# Run - it's that simple!
turbo build

  }
}

Total config complexity: ⭐⭐⭐⭐⭐ (5/5 - Dead simple)

🔍 Deep Dive: Nx

What It Is

Nx is a comprehensive monorepo framework with advanced features like code generation, dependency graph visualization, and affected command detection. Think "Swiss Army knife" of monorepo tools.

Pros ✅

1. Advanced Code Generation - Powerful generators and schematics
2. Visual Dependency Graph - Beautiful interactive graph UI
3. Affected Commands - Only run tasks on changed code
4. Plugin Ecosystem - 50+ official and community plugins
5. Enterprise Features - Best for large teams (50+ developers)

Cons ❌

1. Configuration Complexity - 200+ lines of config typical
2. Steeper Learning Curve - 2-3 days to become productive
3. Slower Builds - Node-based vs Turborepo's Go
4. Opinionated - Forces certain patterns and structure
5. Overkill - Too many features for small teams

Best For

• ✅ Large enterprises (100+ packages)
• ✅ Teams needing code generation
• ✅ Angular monorepos (Nx origin story)
• ✅ Complex microservice architectures

Why I didn't choose it: 90% of features would be unused in my project

🔍 Deep Dive: Lerna

What It Is

Lerna was the original JavaScript monorepo tool (2015) but is now in maintenance mode. Babel, Jest, and React used it historically.

Pros ✅

1. Battle-Tested - Used by major projects for years
2. Simple Publishing - Great for npm package publishing
3. Well-Documented - Years of Stack Overflow answers

Cons ❌

1. Maintenance Mode - Minimal updates since 2022
2. Slow - No modern caching or parallel execution
3. Legacy Architecture - Built before modern tools existed

Why I didn't choose it: Dead end technology, better alternatives exist

🧪 Real-World Testing

My Testing Setup

Machine: MacBook Pro M2, 16GB RAM

Project: 10 packages (2 apps, 2 libs, 1 CLI, 5 configs)

Dependencies: ~150 npm packages total

Test Date: November 2025

Test 1: Cold Build (No Cache)

Winner: Turborepo (3x faster than Nx, 16x faster than Lerna)

Test 2: Cached Build (No Changes)

Winner: Turborepo (4x faster with better caching)

Test 3: Incremental Build (1 Package Changed)

Winner: Turborepo (2.6x faster than Nx)

Real-World Impact

Before Turborepo (manual builds):

• Time per full build: ~5 minutes
• Builds per day: 50+
• Daily time wasted: 4+ hours

After Turborepo:

• Time per full build: 0.3s (cached) / 2.8s (cold)
• Builds per day: 50+
• Daily time saved: 3.5 hours ⚡

ROI: Paid for itself in 1 day of development

🏆 The Decision

I chose Turborepo for 3 compelling reasons:

✅ Reason 1: Speed Without Complexity

My Project Reality:

• 10 packages (small-medium monorepo)
• Solo developer (now), 2-5 team (future)
• Need fast iteration, not enterprise features

Turborepo's Fit:

• 15-minute setup vs 4 hours for Nx
• 73 lines of config vs 300+ for Nx
• 3x faster builds than Nx
• Zero learning curve (if you know npm scripts, you know Turbo)

Impact:

• Setup time: 15 mins (vs 4 hours for Nx)
• Maintenance: ~10 mins/month
• Team onboarding: 30 mins (vs 2 days for Nx)

✅ Reason 2: Vercel Integration

My Deployment:

• Portfolio: Vercel (Next.js)
• Future apps: Vercel (Next.js)
• Remote cache: Vercel (free on hobby plan)

Turborepo's Fit:

• Built by Vercel = best integration
• Remote cache included in Vercel deploy
• Zero config for Vercel deployment
• Automatic cache warming in CI

Impact:

• CI/CD build time: 1m 30s (vs 4m 20s with Nx)
• Remote cache: Free (vs $20/mo for Nx Cloud)
• Deploy time: Instant (cached builds)

✅ Reason 3: Right-Sized Features

What I Actually Need:

• ✅ Fast builds - Turborepo: Best in class
• ✅ Task dependencies - Turborepo: Simple dependsOn
• ✅ Parallel execution - Turborepo: Automatic
• ✅ Caching - Turborepo: Local + remote
• ✅ Watch mode - Turborepo: Built-in

What I Don't Need (Nx advantages):

• ❌ Code generators - I prefer manual control
• ❌ Visual dependency graph - 10 packages = simple
• ❌ Affected commands - Small repo = fast anyway
• ❌ 50+ plugins - Not using Angular/enterprise stack

⚠️ Trade-offs I Accepted

1. No Visual Graph - I can live with --graph DOT output
2. No Generators - Happy to copy/paste boilerplate
3. Smaller Community - Still 25k stars, active Discord

The Tipping Point

Testing both tools for 2 days, the moment was clear:

With Turborepo: pnpm add turbo, create 20-line config, done. Builds flying.

With Nx: 2 hours into docs, still configuring, wondering if I need all these features.

For a solo dev building a 10-package monorepo, Turborepo was obvious.

🛠️ Implementation Guide

Step 1: Install (2 minutes)

# Install Turborepo
pnpm add -D turbo

# Verify installation
turbo --version

Step 2: Create turbo.json (5 minutes)

{
  "$schema": "https://turbo.build/schema.json",
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": ["dist/**", ".next/**", "build/**"]
    },
    "dev": {
      "cache": false,
      "persistent": true
    },
    "lint": {
      "dependsOn": ["^build"]
    },
    "test": {
      "dependsOn": ["^build"],
      "outputs": ["coverage/**"]
    }
  }
}

Step 3: Update package.json (3 minutes)

{
  "scripts": {
    "build": "turbo build",
    "dev": "turbo dev --parallel",
    "lint": "turbo lint",
    "test": "turbo test"
  }
}

Step 4: Test It (5 minutes)

# Full build with caching
pnpm build

# Run again - should be instant
pnpm build

# Parallel dev mode
pnpm dev

Total setup time: ⏱️ 15 minutes

Remote Cache (Optional, 5 minutes)

# Link to Vercel for free remote cache
npx turbo login
npx turbo link

# Now your team shares cache!

🔄 When to Choose Differently

Choose Nx If:

• ✅ You have 50+ packages in your monorepo
• ✅ You need extensive code generation (Angular-style)
• ✅ You want visual dependency graph UI
• ✅ Your team is already trained on Nx
• ✅ You need affected commands for massive repos

Scenario: Enterprise with 100 microservices, 50 developers, complex build rules

Choose Lerna If:

• ✅ You're maintaining an existing Lerna monorepo
• ✅ Migration cost outweighs benefits
• ✅ You only need basic npm publishing

Scenario: Legacy project, no active development, just maintenance

Choose pnpm Workspaces Only If:

• ✅ You have 2-3 packages (tiny monorepo)
• ✅ Builds are already fast (<10s)
• ✅ You want zero dependencies

Scenario: Personal project with one app + one shared library

Choose Rush If:

• ✅ You have 100+ packages (mega monorepo)
• ✅ Turborepo/Nx scale limits hit
• ✅ You need extreme customization

Scenario: Microsoft-scale monorepo (rare)

🎬 Final Verdict

The Bottom Line

Turborepo delivered exactly what I needed:

• ✅ 3x faster builds than Nx (2.8s vs 8.3s cold)
• ✅ 10x simpler config (20 lines vs 200+)
• ✅ 95% cache hit rate = instant rebuilds
• ✅ Free remote cache with Vercel integration
• ✅ 15-minute setup vs 4 hours for Nx

ROI: Saved 3.5 hours/day in build time = $5000/month in productivity

My Recommendation

Use Turborepo if you:

• Have 2-30 packages (small-medium monorepo)
• Value speed and simplicity over features
• Deploy to Vercel (Next.js apps)
• Solo or small team (<20 people)

Use Nx if you:

• Have 50+ packages (large monorepo)
• Need advanced code generation
• Enterprise team (50+ developers)
• Want all-in-one tooling framework

1 Week Later: Retrospective

What I got right:

• Turborepo's speed is real - 95% cache hit rate in practice
• Simple config = easy for future team members
• Vercel integration saves $20/mo on remote cache

What surprised me:

• Even simpler than expected - rarely touch turbo.json
• Caching works better than benchmarks suggested
• Community smaller but highly responsive

Would I choose it again?

Yes, absolutely. For my use case (solo → small team, 10 packages, Vercel deployment), Turborepo is perfect. If I scale to 50+ packages or need code generation, I'll reassess.
