Nx and Turborepo: choosing a task runner for monorepos

Turborepo focuses on fast task orchestration and remote caching with minimal config. Nx adds a rich project graph, generators, module boundary enforcement, and first-class plugins for React/Next/Node.

Caching model#

Both cache build/test outputs; Nx historically leaned on computation hashing with explicit inputs while Turborepo emphasizes content-based hashing via turbo.json. Read current docs—both ecosystems converge on similar ideas over time.

When Turborepo fits#

Small-to-medium JS monorepos (a few apps + packages) that mainly need cache and pipeline speed with low ceremony.

When Nx fits#

Large enterprises needing enforced architecture (eslint module boundaries), code generators, and deep integrations with many frameworks in one workspace.

Using both#

Some teams run Nx for graph/generators and Turborepo for cache—possible but adds complexity; justify with measured pain points.

Summary#

Pick Turborepo for speed and simplicity; pick Nx when governance and scaffolding matter as much as cache hits. Re-evaluate yearly—both tools ship quickly.
