Turborepo vs Nx for SaaS Monorepos in 2026

TL;DR

Both Turborepo and Nx are production-ready monorepo tools used by major SaaS boilerplates. Turborepo wins on simplicity, speed of onboarding, and zero-config caching — making it the default choice in starters like Makerkit Turbo, Supastarter, and Bedrock. Nx wins on power, flexibility, and large-scale code generation — it's the choice for teams building multi-app platforms, monorepos with 50+ packages, or enterprise SaaS with complex CI/CD orchestration. For a typical SaaS boilerplate: start with Turborepo.

Key Takeaways

  • Turborepo is faster to adopt — zero-config remote caching with Vercel, simple turbo.json task graph, no learning curve for standard Next.js monorepos
  • Nx scales further — plugin ecosystem, code generators, project graph visualization, and fine-grained dependency analysis are unmatched
  • Most top SaaS boilerplates use Turborepo — Makerkit Turbo, Supastarter, Bedrock, T3 Turbo all ship Turborepo by default
  • Nx is worth the complexity at scale — if your monorepo will exceed 10 apps or 50 packages, Nx's power becomes necessary
  • Remote caching is table stakes for both — Turborepo uses Vercel Remote Cache (free for Vercel users), Nx Cloud offers a generous free tier
  • Migration between them is painful — choose early, because switching is non-trivial

The Monorepo Problem in SaaS Boilerplates

Modern SaaS products aren't single web apps anymore. A typical production SaaS in 2026 might include:

  • The main Next.js web app (apps/web)
  • A marketing site with different deployment cadence (apps/marketing)
  • A React Native / Expo mobile app (apps/mobile)
  • Shared UI component library (packages/ui)
  • Shared TypeScript types (packages/types)
  • Shared API client (packages/api)
  • Shared utility functions (packages/utils)

Managing this without a monorepo tool means manually syncing versions, running builds in the right order, and waiting for everything to rebuild even when you only changed one package. Monorepo tools solve this by building a task dependency graph, caching outputs, and running tasks in parallel.

Turborepo and Nx are the two dominant solutions in the TypeScript/Next.js ecosystem. Both are widely adopted by SaaS boilerplates — but they make very different architectural bets.

Turborepo: Simplicity-First Monorepo Orchestration

Turborepo (acquired by Vercel in 2021) is built around a single principle: incremental computation. You define a task graph in turbo.json, run turbo build, and Turborepo figures out what can run in parallel, what can be skipped from cache, and what needs to run fresh.

How It Works

// turbo.json
{
  "pipeline": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": [".next/**", "dist/**"]
    },
    "lint": {
      "outputs": []
    },
    "test": {
      "dependsOn": ["build"],
      "outputs": ["coverage/**"]
    },
    "dev": {
      "cache": false
    }
  }
}

That's largely it. The ^build syntax means "run build in all dependencies first." Turborepo handles the rest — parallel execution, local file caching, and optional remote caching via Vercel's cache infrastructure.

Remote Caching

Turborepo's killer feature for SaaS teams is remote cache sharing. When you run turbo build with a linked Vercel project, outputs are uploaded to a shared cache. Your teammates, CI servers, and preview deploys all share the same cache. A build that takes 4 minutes locally runs in 8 seconds on CI if nothing has changed in the affected packages.

For teams deploying on Vercel, this is free and requires no configuration. For teams deploying elsewhere, you can self-host the cache server or use a third-party compatible implementation.

What SaaS Boilerplates Use Turborepo

Makerkit Turbo is the reference implementation. Makerkit's "Turbo" variant organizes the entire SaaS stack into a clean package structure:

apps/
  web/          ← Next.js SaaS app
  e2e/          ← Playwright tests
packages/
  ui/           ← shadcn/ui components
  features/     ← feature modules (billing, auth, etc.)
  core/         ← shared business logic
  cms/          ← blog/content integration
  email/        ← React Email templates

Each feature is a separate package that can be installed or excluded independently. Turborepo ensures they all build in the right order.

Supastarter follows a similar pattern — the monorepo structure separates the web app, API layer, and email templates, with Turborepo orchestrating task execution.

Bedrock and T3 Turbo both use Turborepo as well, for the same reason: it works out of the box with minimal configuration, and the Vercel integration is seamless.

Turborepo Strengths

Turborepo Limitations

  • No code generators — you can't scaffold a new package or page from the CLI
  • Limited project graph UI — turbo run --graph produces a basic visualization, not an interactive explorer
  • Less granular dependency analysis — Turborepo understands packages but not files within packages
  • No built-in project constraints — you can't enforce "apps/ can only import from packages/, never the reverse"

Nx: Power-First Monorepo Platform

Nx (by Nrwl) takes the opposite approach from Turborepo. Where Turborepo is a fast task runner with caching, Nx is a full monorepo platform with code generators, project graph visualization, dependency constraints, migration tools, and a plugin ecosystem covering every major framework.

How Nx Works

Nx uses a project graph built from package.json dependencies AND explicit @nx/enforce-module-boundaries rules. Every package gets a project.json with its own targets (build, test, lint, serve), and Nx tracks which source files affect which outputs.

The critical difference from Turborepo: Nx understands file-level dependencies, not just package-level ones. If you change a single TypeScript file in packages/ui, Nx knows exactly which packages and apps import that file (transitively), and only retests those affected projects. Turborepo invalidates the entire package's cache when any file in it changes.

Nx Code Generators

This is Nx's biggest advantage over Turborepo for growing SaaS teams:

# Generate a new Next.js app in the monorepo
nx g @nx/next:app my-new-dashboard

# Generate a shared library
nx g @nx/js:lib my-feature

# Generate a React component
nx g @nx/react:component MyComponent --project=ui

Every generator creates files, updates project.json, updates tsconfig.json references, and handles imports — consistently, every time. For a team adding features monthly, this saves hours of boilerplate setup and prevents structural drift.

Project Graph Visualization

nx graph opens an interactive browser-based visualization of your entire monorepo — which apps depend on which packages, which packages have circular dependencies, and which projects are affected by a given change. For large monorepos, this is invaluable for architecture reviews and debugging CI failures.

Module Boundary Enforcement

Nx lets you define rules like "apps can import from packages, but packages cannot import from apps." Violations become TypeScript errors via an ESLint plugin:

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

This prevents the architectural decay that kills most monorepos at scale — circular dependencies, apps importing from other apps, feature packages depending on UI-specific packages.

Nx Cloud and Remote Caching

Nx Cloud provides remote caching similar to Turborepo's Vercel integration, with a generous free tier (up to 500 cache hours/month). For teams not on Vercel, Nx Cloud is typically simpler to configure than self-hosted Turborepo cache alternatives.

Nx Cloud also provides distributed task execution — splitting a large test suite across multiple CI agents with automatic work distribution. Turborepo doesn't have a native equivalent.

Which Boilerplates Use Which?

Turborepo-Based Starters

  • Makerkit Turbo — The gold standard Turborepo + Next.js SaaS monorepo. Clean package separation, plugin architecture, Supabase or Firebase.
  • Supastarter — Turborepo monorepo with Next.js + Supabase, strong i18n support.
  • Bedrock — Enterprise-grade Turborepo setup with TypeScript strict mode, testing, and Docker.
  • T3 Turbo — Free, community-maintained Turborepo starter with T3 stack (tRPC, Prisma, NextAuth).

Nx-Based Starters

Most Nx-based starters target enterprise or large-scale applications and aren't sold as "boilerplates" in the traditional sense. Nx's own template gallery (nx.dev/starters) has official Next.js and React starters, and community plugins exist for Supabase and Prisma.

For SaaS specifically, Nx shines when you're building a platform — multiple apps sharing a common feature set — rather than a single SaaS product. Think "agency building 5 similar SaaS products on shared infrastructure."

Making the Choice

Start with Turborepo if:

  • Your SaaS boilerplate has 2–10 packages
  • Your team is small (1–8 developers)
  • You're deploying on Vercel and want free remote caching
  • You want to ship features, not configure tooling
  • You're evaluating Makerkit, Supastarter, or Bedrock (they all use Turborepo)

Choose Nx if:

  • You need consistent code generation across a large team
  • Your monorepo will grow to 50+ packages or 10+ apps
  • You need module boundary enforcement to maintain architecture
  • You're building a multi-product platform, not a single SaaS
  • Your CI runs take over 10 minutes and need distributed execution

The honest truth for most indie SaaS builders: you will never hit Turborepo's limitations. Turborepo at 10 packages with a 2-person team is completely sufficient for years of growth. Pick a Turborepo-based boilerplate (Makerkit Turbo is the best-structured), ship your product, and revisit monorepo tooling when you actually hit the pain points Nx solves.
