Turborepo vs Nx vs Moon: Monorepo Tools 2026
Turborepo vs Nx vs Moon: Monorepo Tools 2026
TL;DR
Turborepo is the right default for most JavaScript/TypeScript monorepos — simple setup, excellent caching, and Vercel Remote Cache. Nx wins for enterprise teams that need a full monorepo platform with code generators, affected-command intelligence, and first-class Angular/React support. Moon is the sleeper pick for polyglot repos (Node.js + Rust + Go) or teams that want reproducible toolchain management baked in.
Key Takeaways
- Nx: ~5M weekly downloads — richest ecosystem, generators, affected commands, Nx Cloud
- Turborepo: ~2M weekly downloads — simplest setup, Vercel-backed, Rust-based task runner
- Moon: ~50K weekly downloads — Rust-based, polyglot support, built-in toolchain management
- Turborepo can reduce build times by 70% in large JS/TS monorepos with remote caching
- Nx benchmarks show 7x better performance than Turborepo in large-scale open-source tests
- Moon manages language versions automatically — no more mismatched Node.js across machines
- All three support remote caching — Vercel, Nx Cloud, and moonrepo.dev respectively
The Monorepo Build Problem
Without a build orchestration tool, a 50-package monorepo rebuilds everything on every CI run. With task caching, only packages with changed inputs rebuild. At scale, this difference is 10-50x in CI time.
The three tools in this comparison take different approaches to that core problem: Turborepo optimizes for simplicity and speed, Nx for completeness and enterprise scale, and Moon for reproducibility and polyglot correctness.
Understanding what these tools actually do is important before choosing one. They are not workspace managers — pnpm workspaces, npm workspaces, and Yarn workspaces handle package installation and linking. What Turborepo, Nx, and Moon add on top is task orchestration: knowing which tasks depend on which other tasks, caching the outputs of tasks that haven't changed, and running tasks in the right order with maximum parallelism. A monorepo without one of these tools will still work — but every CI run will be slow, and developers will spend time waiting for builds that don't need to run.
The "remote caching" feature is where the real ROI materializes. Without remote caching, developer A's cached builds aren't shared with developer B or with CI. With remote caching, if CI already built and tested a package on the main branch, the next developer who pulls that code gets the cached output immediately — zero rebuild time. For large teams, remote caching can eliminate 80-90% of total build time.

Turborepo
Turborepo (acquired by Vercel in 2021) is the gateway drug of monorepo tooling. The turbo.json configuration is minimal, the caching is automatic, and setup from a standard pnpm workspace takes under an hour.
// turbo.json
{
"$schema": "https://turbo.build/schema.json",
"tasks": {
"build": {
"dependsOn": ["^build"],
"inputs": ["src/**", "package.json", "tsconfig.json"],
"outputs": ["dist/**", ".next/**"]
},
"test": {
"dependsOn": ["^build"],
"inputs": ["src/**", "tests/**"]
},
"lint": {
"inputs": ["src/**", "eslint.config.js"]
},
"dev": {
"cache": false,
"persistent": true
}
}
}
# Run builds across all packages (cached)
npx turbo build
# Run only affected packages (based on git diff)
npx turbo build --filter=...[HEAD^1]
# Remote cache via Vercel
npx turbo login
npx turbo link
Turborepo's caching model is file-hash based: if the inputs (source files, env vars, package.json) haven't changed, the outputs are restored from cache. Remote cache allows teams to share this across CI runs and developer machines.
Package filtering is Turborepo's daily workflow tool:
# Only the web app and its dependencies
npx turbo build --filter=@acme/web...
# Only packages changed since main
npx turbo test --filter=...[origin/main]
# Exclude a package
npx turbo build --filter=!@acme/legacy
What Turborepo doesn't have: code generators, advanced project graph visualization, or first-class framework scaffolding. It's a task runner with caching — excellent at that, nothing more. This scope limitation is deliberate. The Turborepo team believes the tool should stay focused on task orchestration and let pnpm workspaces handle package management and developers handle code generation via other tools. Whether this is a strength or a weakness depends entirely on your team's needs.
Turborepo's integration with Vercel Remote Cache deserves special mention. If you're deploying to Vercel, remote caching is free and zero-configuration — turbo login && turbo link and you're done. Builds from CI share caches with local development. Vercel also caches Turborepo outputs as part of build steps, meaning preview deployment builds can reuse the CI cache. This tight integration is a genuine advantage for Vercel users that Nx and Moon can't match.
The Rust rewrite (from Go, completed in 2024) improved Turborepo's performance significantly. Hash computation, file scanning, and graph traversal are all faster. For repos with thousands of files, the cold-start time (no cache hit) improved by 30-40%. Hot-path performance (most tasks cached) was already fast and remained so.
When Turborepo is the right choice:
- JavaScript/TypeScript-only monorepos starting from scratch
- Teams that want minimal configuration overhead and fast onboarding
- Vercel-deployed projects where native Remote Cache integration is a hard advantage
- Repos with 5-50 packages where Nx's feature depth isn't needed or wanted
Nx
Nx (by Nrwl) is the most feature-complete monorepo solution in the JavaScript ecosystem. It's been the enterprise standard for large Angular and React codebases for years and has expanded to support virtually every modern framework.
// nx.json
{
"$schema": "./node_modules/nx/schemas/nx-schema.json",
"defaultBase": "main",
"targetDefaults": {
"build": {
"cache": true,
"dependsOn": ["^build"],
"inputs": ["production", "^production"]
},
"test": {
"cache": true,
"inputs": ["default", "^production", "{workspaceRoot}/jest.preset.js"]
}
},
"namedInputs": {
"default": ["{projectRoot}/**/*", "sharedGlobals"],
"production": ["default", "!{projectRoot}/**/?(*.)+(spec|test).[jt]s?(x)"]
}
}
# Generate a new React library
nx generate @nx/react:library ui-components --bundler=vite
# Run affected tests (smarter than Turborepo's filter)
nx affected:test --base=main
# Visualize the project graph
nx graph
# Migrate to latest Nx version (automated)
nx migrate latest && nx migrate --run-migrations
Nx's affected commands are more sophisticated than Turborepo's filters: Nx builds a full dependency graph and knows exactly which projects are affected by any file change, including through transitive dependencies. This can mean running 3 packages instead of 15 in a large monorepo. Turborepo's --filter=...[HEAD^1] is simpler and covers most cases, but Nx's affected analysis uses deeper dependency tracking that can be more accurate in complex repos where a shared utility is consumed by many packages.
Nx Cloud provides distributed task execution — tasks fan out across multiple agents automatically, with no manual CI matrix configuration. For large teams, this can reduce CI time from 30 minutes to 5. The Nx Cloud free tier covers small teams, and enterprise pricing is per-seat for larger organizations. This pricing model makes Nx Cloud an easier sell than Turborepo Remote Cache at scale, since Turborepo's remote cache is free on Vercel but requires a paid plan or self-hosting for non-Vercel deployments.
Nx's code generators (called "generators" or formerly "schematics") are its most powerful differentiator for large teams. Running nx generate @nx/react:library ui-components creates the library, sets up the project configuration, adds it to the workspace graph, and generates test scaffolding — all in seconds. For organizations that create dozens of new packages per year, this consistency is significant. Without generators, new packages are created manually, leading to drift in how packages are structured, tested, and bundled.
The Nx migration story is also a practical advantage. If you start with Turborepo and outgrow it, nx migrate has tooling to help. Nx maintains a Turborepo-to-Nx migration guide with automated transforms. This migration path is documented, tested, and used by teams that started simple and grew into Nx's feature set.
When Nx is the right choice:
- Large teams (10+ developers) who benefit from code generators and standardized project structure
- Angular or NestJS projects (Nx has the best Angular support in the ecosystem)
- Repos where affected-command intelligence meaningfully reduces CI scope
- Organizations willing to invest in Nx Cloud for distributed execution across CI agents
Moon
Moon (by moonrepo) is the newest of the three and solves a different class of problems: reproducibility and polyglot correctness. Its killer feature is toolchain management — Moon installs and pins Node.js, pnpm, Bun, Deno, and even Rust and Go versions for each workspace, ensuring every developer and CI run uses identical versions.
# .moon/workspace.yml
projects:
- "apps/*"
- "packages/*"
- "services/*"
vcs:
manager: git
defaultBranch: main
# .moon/toolchain.yml
node:
version: "22.11.0"
packageManager: pnpm
pnpmVersion: "9.15.0"
rust:
version: "1.82.0"
# moon.yml (per-project)
language: typescript
type: library
tasks:
build:
command: tsc --build
inputs:
- "src/**/*"
- "tsconfig.json"
outputs:
- "dist"
test:
command: vitest run
inputs:
- "src/**/*"
- "tests/**/*"
# Run tasks across all projects
moon run :build
# Run for specific project
moon run web:build
# Check affected projects
moon ci --base=main --head=HEAD
Moon's remote caching (moonrepo.dev) is free for open-source and affordable for teams. The Rust implementation ensures fast graph traversal even in massive repos.
Moon's approach to the Node.js version problem is worth explaining more concretely. The .moon/toolchain.yml file declares the exact Node.js version (and package manager version) the workspace requires. Moon installs and manages these versions automatically — similar to nvm or volta, but integrated into the build system and applied consistently across all tasks. This means you can't accidentally run a build with Node.js 20 when the project requires Node.js 22, because Moon is managing the runtime. For teams where "works on my machine" CI failures have been a recurring problem, this automatic toolchain management is a significant quality-of-life improvement.
The polyglot story is Moon's most unique feature. A workspace that has JavaScript services, a Rust CLI tool, and Go microservices can all be managed in one moon.yml dependency graph. Moon knows which Rust services need to be rebuilt when a shared type library changes, and which JavaScript services depend on the compiled Rust CLI. Turborepo and Nx are fundamentally JavaScript-centric tools; Moon is language-agnostic by design.
Moon's smaller community (50K weekly downloads vs Turborepo's 2M) is a practical consideration. There are fewer tutorials, fewer GitHub issues documenting edge cases, and fewer team members who will already know the tool when you hire them. The trade is worth making if your use case genuinely requires polyglot support or toolchain management — but for JavaScript-only repos, the community size difference is a real cost.
When Moon is the right choice:
- Polyglot monorepos mixing Node.js, Rust, Go, or Python in the same dependency graph
- Teams burned repeatedly by Node.js or package manager version mismatches across machines
- Projects where deterministic builds are a compliance or reliability requirement
- CI environments where toolchain reproducibility needs to be guaranteed, not assumed
When to Choose Each
Choose Turborepo as your default for JavaScript/TypeScript monorepos. It's the simplest path to caching and the easiest to maintain. If you're on Vercel, the free remote cache seals the deal. If you outgrow it, migrating to Nx has official tooling and is well-documented. Don't overthink the initial choice — Turborepo's simplicity means the cost of being wrong is low.
Choose Nx when you need a true monorepo platform — generators, affected intelligence, distributed task execution, and first-class framework support. The configuration cost is justified at scale. If your organization is creating multiple new packages per month, Nx's generators pay for themselves quickly in consistency and reduced bootstrapping time.
Choose Moon when language reproducibility matters more than ecosystem breadth, or when your repo spans multiple programming languages. It's the most principled approach to the "works on my machine" problem, and its toolchain management feature alone is worth evaluating if you've had Node.js version drift issues in CI.
The decision gets easier if you frame it as a progression: most teams should start with Turborepo, evaluate Nx when generators and affected commands become important, and consider Moon if polyglot support or strict toolchain reproducibility becomes a requirement. These are not competitors fighting for the same team — they serve different stages and different types of monorepos.
