The landscape: Turborepo (caching focus), Nx (plugin ecosystem), pnpm workspaces (minimal, native), Bun workspaces (fast, batteries-included).
Quick decision tree
2-3 packages, no CI bottleneck → pnpm workspaces.
Heavy CI, many TS packages → Turborepo.
Polyglot, multiple frameworks → Nx.
Greenfield, Bun-only → Bun workspaces.
Don't over-engineer. Most teams pick Turbo and never touch the cache settings.
Why this decision matters more in 2026
A monorepo tool is the foundation under every other build decision you make. It dictates how fast CI runs, how easily new engineers onboard, how cleanly you can extract a package, and how much your release process hurts. Picking wrong is not catastrophic — every tool here can be replaced — but the cost of switching grows linearly with package count and team size. Spend an afternoon on the decision now; you will save a week of migration later.
The good news: the four serious options in 2026 are all genuinely good. There is no "obvious wrong answer." The bad news: each tool is opinionated, and adopting one without understanding those opinions is how teams end up rewriting their CI six months later.
The right monorepo tool is the one whose defaults match your team's actual workflow — not the one with the prettiest dashboard.
The contenders
Turborepo
Caching-first. Turbo's core value is "never run the same task twice," and it delivers that with a remote cache that works out of the box on Vercel and self-hosts in ~20 lines of config. It stays out of the way for everything else, which is both its strength (low cognitive overhead) and its limit (you bring your own conventions).
Nx
Plugin-first. Nx ships generators, executors, dependency graphs, and affected-detection for ~30 frameworks. If your monorepo is polyglot (React + NestJS + React Native + Go), Nx gives you a single command surface across all of them. The trade-off is that Nx wants to own your workflow — embrace it and it is delightful, fight it and it is painful.
pnpm workspaces
Minimal. No task runner, no caching, no graph — just pnpm -r run build and a sane node_modules layout. For 2–10 packages, this is often all you need. Pair it with pnpm --filter ... for selective runs and a homegrown caching layer if CI gets slow.
Bun workspaces
Fast. Bun's workspace support is solid in 2026, and bun install is dramatically faster than alternatives. The task runner is rudimentary compared to Turbo/Nx, but for greenfield Bun-only projects the integrated story is hard to beat.

Lock-in risk is the underrated axis. Turbo and pnpm are easy to leave. Nx generators write code that assumes Nx — leaving means rewriting that code.
A decision tree that actually works
Start here
Do you have 2–4 packages and CI under 5 minutes? Use pnpm workspaces. Anything else is over-engineering.
Is the project greenfield, Bun-first, and unlikely to need polyglot support? Use Bun workspaces.
Do you have many TypeScript packages and CI pain? Use Turborepo.
Are you polyglot (multiple frameworks, possibly multiple languages) and willing to adopt opinions? Use Nx.
Tiebreakers
If your team already uses Vercel, Turborepo's remote cache is free and zero-config.
If you ship a design system across many apps, Nx generators reduce the per-app boilerplate dramatically — relevant if you also migrated to Tailwind v4.
If your CI runs Docker builds, pair any choice with the Docker Builder Guide to keep image caches warm.
Real use cases
A two-person startup shipping a React app + a marketing site
pnpm workspaces. One packages/ui shared library, two consumers, no task runner. Adding Turbo here is a solution looking for a problem.
A 15-engineer company with a React app, a NestJS API, and a shared TS contracts package
Turborepo. The caching pays for itself within a week, and the conventions stay invisible. CI drops from 12 minutes to 3.
A 60-engineer enterprise with React, React Native, NestJS, Go services, and a design system
Nx. The generators, the dependency graph, and the affected-detection across languages are worth the learning curve. The investment in custom Nx executors becomes a moat.
A Bun-only side project with three packages
Bun workspaces. bun install in 200 ms, bun run --filter '*' build covers the basics, and you ship faster than you would have spent setting up Turbo.
CI patterns that pay off regardless of tool
Cache the package manager store
pnpm store, Bun's global cache, and Nx's node_modules cache all benefit from explicit CI caching keyed on the lockfile hash. This is the single biggest CI win across every tool.
Run affected, not all
Whether you call it turbo run build --filter=...[HEAD^], nx affected -t build, or a custom git diff script, only building changed packages drops CI time by 60–90% on a healthy monorepo.
Pin the tool version
packageManager in package.json for pnpm/Bun, and a fixed Turbo/Nx version in devDependencies. Floating versions in a monorepo cause the worst kind of "works on my machine" bug.
Keep one CI entry point
ci/run.sh that delegates to the tool. When you eventually switch tools, you change one file.
Key takeaways
pnpm workspaces is the right default for small repos.
Turborepo wins for TS-heavy monorepos with CI pain.
Nx wins for polyglot enterprise repos that benefit from generators.
Bun workspaces wins for greenfield, Bun-only projects.
Pin tool versions, cache the store, and always run affected — these matter more than the tool choice.
FAQ
Can I mix pnpm workspaces and Turborepo? Yes — that is the most common production setup. pnpm handles installation, Turbo handles task orchestration and caching.
Is Nx overkill for a 10-package repo? For a homogeneous TS repo, yes. For a polyglot repo, no. The line is "do you have more than two frameworks?"
Does Bun replace Turbo? Not yet. Bun is a fast package manager and runtime; Turbo is a task orchestrator with remote caching. They can coexist (packageManager: bun with Turbo on top).
How do I migrate from Lerna? Lerna is effectively legacy in 2026. Most teams move to pnpm workspaces + Turbo. The migration is mechanical: delete lerna.json, add pnpm-workspace.yaml, replace lerna run with turbo run.
What about Rush / Bazel? Rush is solid but losing momentum. Bazel is correct for massive (1000+ package) polyglot monorepos and overkill for everything else.
Conclusion
The 2026 monorepo landscape is healthy enough that you do not need to agonize over the choice. Pick the simplest tool that solves your current pain — pnpm workspaces until CI hurts, Turborepo when it does, Nx when polyglot complexity dominates, Bun when you are starting from scratch and Bun-only. Wrap whatever you pick in a single CI entry point so the next migration is a one-file change, and spend the rest of your energy on the work the monorepo actually contains.
Anti-patterns to avoid
Adopting a task runner before you need one A two-package repo with a 30-second build does not need Turbo or Nx. Adding either means onboarding cost, configuration files, and a learning curve that pays back only when CI hurts. Wait for the pain; then solve it.
Pinning everyone to a custom Nx executor Nx executors are powerful but viral — every package that uses one is now bound to the executor's API. Use built-in executors wherever possible, and write custom ones only when the productivity win is undeniable.
Caching without invalidation discipline A remote cache that returns stale outputs is worse than no cache at all. Be explicit about inputs (env vars, file globs, tool versions) for every cached task. The first time CI ships a cached "green" build that should have failed, the team loses trust in the cache forever.
Letting workspace dependencies drift workspace:* is convenient but loose. For published packages, pin to exact versions and bump them with a changesets-style workflow. The discipline pays off the first time you publish a breaking change.
Treating the monorepo as a deployment unit Packages share a repo; they should not share a release cadence. Independent versioning, independent CI pipelines, and independent deploys are the point of the monorepo — collapsing them back into a monolith undoes the value. Combine this discipline with the CI patterns from the Docker Builder Guide and the testing flows in the Cypress and Playwright guides for a release pipeline that scales with the repo.
