Monorepos in 2026: Turborepo, Nx, or pnpm Workspaces?

Monorepos have gone mainstream. The benefits are compelling: shared code without npm publishing overhead, atomic commits across packages, simplified dependency management, and consistent tooling across your entire codebase. But the tooling landscape has fragmented, and choosing the right approach for your team matters.

Why Monorepos: The Real Benefits

Shared code without publishing, atomic commits, consistent tooling, and unified dependency management solve real problems as codebases grow. The main cost is complexity: build orchestration, caching, and ensuring changes don't break downstream consumers.

Turborepo: Simple, Fast, Vercel-Backed

Turborepo takes a minimalist approach: it's a build system that sits on top of your existing package manager's workspace support.

// turbo.json
{
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": [".next/**", "dist/**"]
    },
    "test": {
      "dependsOn": ["^build"]
    }
  }
}

Strengths: Zero configuration to start, intelligent caching, remote caching, Vercel integration. Weaknesses: Limited beyond build orchestration, less prescriptive.

Nx: The Enterprise Choice

Nx takes a batteries-included approach with code generation, dependency visualization, affected analysis, and a rich plugin ecosystem.

nx affected:test --base=main

Strengths: Rich tooling, strong conventions, enterprise features. Weaknesses: Learning curve, lock-in concerns, overhead for small projects.

pnpm Workspaces: DIY but Flexible

pnpm workspaces provide monorepo primitives without a dedicated build orchestrator—maximum flexibility, minimum magic.

# pnpm-workspace.yaml
packages:
  - "apps/*"
  - "packages/*"

Best when you want minimal tooling overhead, have custom requirements, or already use pnpm.

Migration Strategies

Phase 1: Inventory. Phase 2: Setup base monorepo. Phase 3: Migrate incrementally. Phase 4: Consolidate tooling.

Recommendations by Team Size

Small teams (1-5): Turborepo. Medium teams (5-20): Either works. Large teams (20+): Nx's enterprise features become valuable.

All three approaches can work well. Choose Turborepo for simplicity, Nx for comprehensive tooling, pnpm workspaces for maximum flexibility.
