Monorepos are mainstream in 2026 — 63% of teams with 50+ developers use them. We compare Turborepo, Nx, Moonrepo, Lerna, and Changesets so you can pick the right build tool for your stack, team size, and scale.
Monorepos have gone mainstream. As of 2026, 63% of companies with 50+ developers use a monorepo approach2, and the tooling has matured to match. But without the right build tool, a monorepo becomes slow and painful — long CI runs, broken caches, and tangled dependency graphs.
The good news: the landscape has consolidated into a handful of well-supported tools, and the right choice depends mostly on your team size, language stack, and how much structure you need1. Here's how to decide.
For JS/TS teams, the real question is Turborepo or Nx1. Both are excellent, but they optimize for different things.
Turborepo is fast and simple. It drops into an existing pnpm or Yarn workspace with minimal config (a single turbo.json), and its Rust engine — migrated from Go in late 2023 — keeps builds snappy6. Vercel's free remote cache means CI gets faster without extra infrastructure. For repos with 5–50 packages, it's hard to beat2.
Nx is a full platform. Beyond task running, it offers code generators, architectural enforcement rules, distributed task execution (DTE), and polyglot plugin support5. Project Crystal (Nx 18+) brought zero-config setup that auto-infers tasks from your existing tool configuration3. The payoff at scale is real: a 40-minute test suite can complete in 6 minutes across 8 agents with DTE3, and Nx outpaces Turborepo by over 7x in large-scale distributed CI scenarios2.
The common migration pattern: start with Turborepo, move to Nx once you pass 50 packages or need features Turbo doesn't offer1.
Not every team fits the Turborepo-or-Nx binary. Here are three more tools worth knowing:
Moonrepo sits between Turborepo's simplicity and Bazel's power. It's Rust-based, polyglot (JS/TS, Python, Go), and includes a toolchain manager called proto. YAML config keeps things readable. It's a good fit for teams who want more structure than Turborepo but less ceremony than Bazel1.
Lerna found its niche: multi-package npm versioning and publishing. It now delegates task running to Nx, so you're not choosing Lerna over Nx — you're adding Lerna when you need to ship multiple related packages to npm with proper versioning, changelogs, and conventional commits3.
Changesets is even lighter. It handles versioning and changelogs for monorepos without the full publishing workflow Lerna provides. It's commonly paired with pnpm + Turborepo for Next.js library teams who just need to bump versions and generate changelogs across packages.
Two tools come up in any monorepo conversation that aren't picks here:
Bazel is the heavyweight. Google built it for massive, polyglot repositories with 1000+ engineers2. If you're at that scale, you probably already know you need it. For most teams, it's overkill4.
pnpm Workspaces is the baseline. It's not a build tool — it's a package manager that handles the dependency graph. Most monorepo setups start with pnpm as the foundation and layer a task runner (Turborepo, Nx, Moonrepo) on top3.
Start simple. pnpm + Turborepo takes less than an hour to set up3 and handles most JS/TS monorepos well. If you outgrow it — you need code generation, architectural rules, or distributed execution at scale — migrate to Nx. If you're polyglot and want a middle ground, look at Moonrepo. And if your pain point is specifically package publishing, add Lerna or Changesets to whatever stack you're running.
Match the tool to your stack and team size. There's no prize for starting with the most powerful option1.
