Turborepo vs Nx vs Moon: Monorepo Tools for Startups in 2026

The monorepo debate is settled. Google, Meta, Microsoft, and Vercel all use monorepos. More importantly, thousands of startups with 3 to 50 engineers have adopted them because the benefits are immediate and the tooling has finally caught up. Shared TypeScript types between your frontend and API. One PR to update a shared utility and every consuming package. Atomic commits that keep your entire system in a consistent state.

But here is the part nobody tells you: the monorepo itself is just a directory structure. The tool you pick to orchestrate builds, manage caching, and run CI across that structure is what determines whether your team ships faster or drowns in configuration. A poorly configured monorepo is worse than separate repos because you inherit all the complexity with none of the benefits.

We have set up monorepos for over 60 startup clients in the past three years. The pattern is consistent. Teams that pick the right tool for their size and complexity save 30 to 60 percent on CI costs within the first quarter. Teams that pick the wrong tool (usually by over-engineering) spend weeks fighting configuration instead of shipping features.

This guide compares the three monorepo orchestrators that matter in 2026: Turborepo, Nx, and Moon. We will cover task orchestration, caching, code generation, CI integration, and migration strategy. More importantly, we will tell you which one to pick based on your team size and project complexity.

Task orchestration is the core job of any monorepo tool. When you run build across 12 packages, the tool needs to figure out the correct order, parallelize where possible, and skip anything that has not changed. The three tools approach this very differently.

Turborepo: Pipeline-Based Simplicity

Turborepo uses a turbo.json pipeline configuration. You declare task dependencies declaratively. If build depends on ^build (the caret means "dependencies' build tasks"), Turborepo topologically sorts your workspace graph and runs everything in the right order with maximum parallelism. The configuration is minimal. A typical turbo.json for a Next.js + shared-ui + API monorepo is about 20 lines.

In our benchmarks on a 9-package TypeScript monorepo (3 apps, 6 libraries), Turborepo executed a full cold build in 47 seconds with 8-way parallelism. The simplicity is genuine. New developers on your team can understand the pipeline in five minutes.

Nx: Fine-Grained Task Graph

Nx builds a more detailed task graph. Beyond simple dependency ordering, Nx understands input and output relationships at the file level. Its project.json or nx.json configuration lets you define targets with explicit inputs (which files affect this task), outputs (what gets produced), and dependencies. This granularity means Nx can make smarter caching and invalidation decisions.

On the same 9-package monorepo, Nx cold build took 44 seconds. The 3-second advantage comes from Nx's more aggressive parallelization and its ability to stream task outputs rather than buffering them. However, the nx.json configuration was 65 lines, and we needed per-project project.json files for custom targets.

Moon: Rust-Powered Project Graph

Moon takes a fundamentally different approach. Written in Rust, it models your entire repository as a project graph with explicit moon.yml files per project. Task definitions live in these YAML files, and Moon's Rust-based resolver builds the dependency and task graph at startup in under 100ms, even for repos with hundreds of projects.

Cold build on our benchmark repo: 42 seconds. Moon's Rust runtime shaves time off the orchestration overhead itself. For small repos the difference is negligible. For repos with 50+ packages, the orchestration overhead savings compound significantly. The tradeoff: Moon's YAML configuration is more verbose than Turborepo's JSON, and the mental model requires understanding both the project graph and the task graph as separate concepts.

The bottom line on orchestration: all three tools handle task ordering and parallelism well. Turborepo wins on simplicity, Nx wins on granularity, and Moon wins on raw speed. For most startup monorepos (under 20 packages), the orchestration differences are negligible. Pick based on the other factors below.

Local caching is table stakes. All three tools hash your inputs and skip tasks when nothing has changed. The real differentiator is remote caching, which shares cache artifacts across your entire team and CI. This is where monorepo tooling pays for itself. A cache hit on a build task that takes 30 seconds saves that time for every developer and every CI run.

Turborepo + Vercel Remote Cache

Turborepo's remote caching is its killer feature. Connect to Vercel Remote Cache with a single npx turbo login command and you are done. Every cached artifact (build outputs, test results, lint results) gets uploaded to Vercel's edge network and shared across your team. Setup takes under two minutes.

In production across our client projects, we consistently see 78 to 92 percent cache hit rates on CI after the first week. On a team of 8 developers working on a 12-package monorepo, this translated to CI pipeline times dropping from 14 minutes to 3.5 minutes on average. That is a 75 percent reduction. Vercel Remote Cache is free for Hobby plans and included in Pro plans. For teams not on Vercel, Turborepo also supports custom remote cache endpoints via the HTTP caching API, so you can self-host with something like Ducktape or a simple S3-backed server.

Nx Cloud

Nx Cloud is the remote caching and distributed task execution layer for Nx. It goes beyond simple artifact caching. Nx Cloud can distribute individual tasks across multiple CI agents, meaning your build and test tasks run in parallel across machines, not just across cores on a single machine. This is called Distributed Task Execution (DTE), and it is genuinely impressive for large repos.

Cache hit rates are comparable to Turborepo (80 to 90 percent in steady state). The distributed execution feature reduced CI times by an additional 40 percent in our tests on a 25-package monorepo compared to single-agent execution. Nx Cloud's free tier gives you 500 computation hours per month. Paid plans start at $99/month for teams. The downside: Nx Cloud is a separate service with its own dashboard, billing, and configuration. It is another thing to manage.

Moon: Self-Hosted or Moonbase

Moon supports remote caching through Moonbase (their hosted solution) or self-hosted backends. The self-hosted option appeals to teams with strict data residency requirements. Moonbase is newer and less battle-tested than Vercel Remote Cache or Nx Cloud, but it works. Cache hit rates are equivalent since the underlying hashing strategies are similar across all three tools.

Our recommendation: if you are already on Vercel (and most Next.js startups are), Turborepo's remote cache integration is unbeatable in terms of simplicity. If you need distributed task execution across CI agents, Nx Cloud is the only option that does this well. If you need self-hosted caching for compliance reasons, Moon or Turborepo's custom cache API both work.

As your monorepo grows, you need a consistent way to add new packages, libraries, and applications. Copying an existing package and find-replacing names is error-prone. Code generators solve this by scaffolding new projects with the correct configuration, dependencies, and boilerplate.

Nx Generators: The Gold Standard

Nx generators are the strongest feature in the entire Nx ecosystem. They provide template-driven code scaffolding with full control over file creation, dependency installation, and configuration updates. Run nx generate @nx/react:library shared-utils and you get a fully configured React library with tsconfig paths, Jest config, ESLint setup, and proper project.json targets. All wired into the monorepo automatically.

Nx ships with first-party generators for React, Angular, Node, Express, Nest, Next.js, and more. You can also write custom generators using the @nx/devkit API. We have built custom generators for clients that scaffold entire microservice packages (API route, database migration, shared types, tests) in a single command. This alone has saved teams 2 to 4 hours per new service.

Turborepo Gen

Turborepo added turbo gen in 2024, and it has matured significantly. You can create custom generators using Plop.js templates. The experience is decent: define a template directory, write Handlebars templates, and run turbo gen to scaffold new packages. It works, but it is less integrated than Nx generators. You still need to manually update tsconfig references and workspace dependencies in some cases.

For teams that value simplicity, Turborepo's generator is good enough. For teams that want fully automated scaffolding with zero manual steps, Nx generators are worth the additional complexity.

Moon: Minimal Built-In Generation

Moon does not have a built-in code generation system comparable to Nx generators or Turborepo gen. You can use external tools (Plop, Hygen, or custom scripts) and integrate them as Moon tasks. This is fine, but it means code generation is not a first-class citizen in the Moon ecosystem. If generators are important to your workflow, this is a meaningful gap.

If your team is building a TypeScript-first monorepo and you plan to add new packages frequently (more than once a month), Nx generators will save you significant time. If you add packages rarely, any approach works.

Your monorepo tool's CI integration determines how much you pay for builds and how long your team waits for green checks. The key feature here is affected detection, which means only running tasks for packages that are actually impacted by the changes in a given PR. Without affected detection, every PR triggers a full build of every package, which defeats the purpose of a monorepo.

Turborepo in CI

Turborepo's turbo run build --filter=...[origin/main] syntax runs tasks only for packages changed since the main branch. Combined with remote caching, this means most CI runs touch only 1 to 3 packages. Setting up Turborepo in GitHub Actions is straightforward. A typical workflow file is 25 lines, and you can find working examples in the official docs.

One pattern we use for clients: run turbo run lint test build --filter=...[origin/main] as a single command. Turborepo handles the task ordering (lint and test in parallel, build after both pass) and caching (skip anything already cached). CI times for PRs that touch a single package consistently come in under 2 minutes when remote cache is warm.

Nx Affected Commands

Nx's affected detection is more sophisticated. nx affected --target=build uses the project graph and file-level dependency tracking to determine exactly which projects are impacted. If you change a shared utility, Nx traces every project that imports from that utility, directly or transitively. This is more accurate than Turborepo's workspace-level change detection in cases where a package has internal modules that are only consumed by specific downstream packages.

Nx also provides nx-cloud GitHub Actions integration that automatically distributes affected tasks across multiple CI agents. For a 30-package monorepo, this can reduce CI times from 20 minutes (single agent) to 5 minutes (4 agents). The tradeoff: you need to configure and pay for multiple CI runners.

Moon's Affected and CI

Moon's moon ci command is purpose-built for CI environments. It automatically determines affected projects, runs tasks in the correct order, and reports results. The CI integration is clean and opinionated. Moon also generates a build report with timing data for every task, which is useful for identifying slow spots in your pipeline.

For setting up CI/CD pipelines, all three tools integrate well with GitHub Actions and CircleCI. Turborepo is the easiest to set up (5 minutes to a working pipeline). Nx offers the most advanced CI features (distributed execution, automatic agent allocation). Moon sits in the middle with a clean, opinionated CI command that works well out of the box.

Most startups do not start with a monorepo. You start with a single Next.js app, maybe a separate API repo, and a handful of shared utilities copy-pasted between projects. At some point, the duplication becomes painful, types drift out of sync, and you decide to consolidate. Here is how to approach that migration with each tool.

The Incremental Approach (Works with All Three Tools)

Do not try to migrate everything at once. The proven approach is to start with a monorepo structure containing your primary app, then gradually move other projects in. Step one: create a new monorepo with your main application as the first workspace package. Step two: extract shared code (types, utilities, UI components) into internal packages. Step three: move your other applications into the monorepo one at a time. Each step should be a separate PR that your team can review and test independently.

Turborepo Migration

Turborepo offers npx create-turbo for new repos and a migration guide for existing repos. The migration is manual but simple. Add a root turbo.json, configure your pipeline, and ensure each workspace has the correct package.json scripts. Turborepo works with npm, yarn, pnpm, and bun workspaces, so you keep your existing package manager.

Typical migration timeline for a 2-app, 3-library setup: 1 to 2 days for a senior developer. Most of that time is spent extracting shared code into packages, not configuring Turborepo itself.

Nx Migration

Nx provides nx init which can be run in an existing monorepo to add Nx on top. This is the smoothest onboarding experience of the three tools. You can adopt Nx incrementally, starting with just caching and affected detection, then adding generators and plugins later. Nx also has an nx migrate command that handles version updates and breaking changes across your Nx configuration automatically.

Migration timeline for the same 2-app, 3-library setup: 2 to 3 days. The extra day is spent configuring project.json files and understanding Nx's plugin system. Once configured, ongoing maintenance is lower because Nx automates more of the workspace management.

Moon Migration

Moon requires creating .moon/workspace.yml at the root and moon.yml files in each project. The configuration is more explicit than Turborepo or Nx, which means the initial setup takes longer but the result is more predictable. Moon also requires specifying the toolchain (Node version, package manager) in its configuration, which provides consistency but adds setup steps.

Migration timeline: 3 to 4 days. Moon's learning curve is steeper because you need to understand its project graph model, task configuration format, and toolchain management. The payoff comes later in repos with 20+ packages where Moon's explicit configuration prevents the ambiguity that can creep into larger Turborepo or Nx setups.

Regardless of which tool you pick, the migration itself is not the hard part. The hard part is extracting clean package boundaries from tangled application code. Spend your energy on that, not on tool configuration.

Beyond the core features, the surrounding ecosystem and developer experience of each tool influence your long-term satisfaction. Let us look at plugins, configuration burden, and one often-overlooked feature: visualizing your dependency graph.

Plugin Ecosystems

Nx has the richest plugin ecosystem by a wide margin. First-party plugins cover React, Angular, Node, Nest, Express, Storybook, Cypress, Jest, Vite, Webpack, and more. Each plugin provides generators, executors (task runners), and automatic dependency detection. Community plugins extend support to technologies like Flutter, Go, and Terraform. If you are using a popular framework, Nx probably has a plugin that understands its build pipeline.

Turborepo intentionally has a minimal plugin system. It relies on your existing package.json scripts and does not try to own your build configuration. This is a feature, not a bug. You configure ESLint, TypeScript, and Vite the same way you always do. Turborepo just orchestrates and caches the results. For teams that dislike "framework lock-in," this approach is refreshing.

Moon has a growing plugin system focused on toolchain management. Plugins define how Moon installs and manages tools (Node, Bun, Deno, Rust, Go). This is unique to Moon and valuable for polyglot repos. If your monorepo contains both TypeScript and Rust packages, Moon's toolchain plugins handle installing and version-managing both runtimes. Turborepo and Nx do not manage runtimes at all.

Configuration Complexity

This is where opinions get strong. Turborepo requires the least configuration: one turbo.json at the root, your existing package.json scripts, and workspace configuration in your package manager. Total new config files: 1. Nx requires nx.json at the root and optionally project.json per project. With plugins, Nx can auto-detect targets from package.json scripts, reducing configuration. But the full Nx experience (generators, executors, custom plugins) requires learning a substantial API surface. Total new config files: 1 to 15 depending on usage. Moon requires .moon/workspace.yml, .moon/toolchain.yml, and moon.yml per project. The configuration is explicit and verbose. Total new config files: 3 to 20+.

Dependency Graph Visualization

All three tools provide dependency graph visualization, and this is one of the most underrated features for onboarding new developers. Nx's nx graph launches an interactive web app showing every project, its dependencies, and the affected projects for any given change. It is the best visualization in the space. Turborepo's turbo run build --graph outputs a Graphviz DOT file or opens a web-based visualizer. It is functional but less polished than Nx's version. Moon's moon project-graph generates a visual graph in the terminal or as an output file. It works but lacks the interactivity of Nx's solution.

For teams where developers frequently ask "what does this package depend on?" or "what will break if I change this?", Nx's graph visualization is a genuine productivity boost.

After building and maintaining monorepos across dozens of client projects, here are our opinionated recommendations. These are not hedged "it depends" answers. We are telling you what to pick.

Pick Turborepo If:

• Your team is 2 to 10 engineers. Turborepo's simplicity means less configuration to maintain and fewer abstractions to learn.
• You are already on Vercel. Remote caching is one command away. The integration is seamless.
• You have fewer than 20 packages. Turborepo handles this scale effortlessly, and you do not need Nx's advanced features.
• You value minimal abstraction. Turborepo does not try to own your build system. It orchestrates and caches your existing scripts.

Expected results: 70 to 85 percent CI time reduction with remote caching. 1-day setup. Near-zero ongoing maintenance.

Pick Nx If:

• Your team is 10 to 50+ engineers. Nx's generators, plugins, and distributed execution scale to large teams and large repos.
• You add new packages frequently. Nx generators save hours per new service or library.
• You need distributed CI execution. Nx Cloud's DTE is the only mature solution for splitting tasks across multiple CI agents.
• You use Angular. Nx was born from the Angular ecosystem and provides the best Angular monorepo experience available.

Expected results: 75 to 90 percent CI time reduction. 2 to 3 day setup. Moderate ongoing maintenance, mostly around keeping plugins and migrations updated.

Pick Moon If:

• Your repo is polyglot. TypeScript, Rust, Go, Python packages in the same repo. Moon's toolchain management is purpose-built for this.
• You want Rust-level performance for orchestration. For repos with 50+ packages, Moon's Rust runtime is measurably faster at graph resolution.
• You need strict reproducibility. Moon's explicit configuration and toolchain pinning ensure builds are reproducible across machines.

Expected results: 70 to 85 percent CI time reduction. 3 to 4 day setup. Higher upfront investment, lower ambiguity at scale.

The Honest Truth

For 80 percent of TypeScript startups in 2026, Turborepo is the right choice. It does the job with minimal fuss, integrates perfectly with the Vercel ecosystem, and you will not outgrow it until you hit 30+ packages or need distributed CI execution. If you start with Turborepo and later need Nx's features, migration is straightforward because both tools work with standard workspace protocols.
