Nx vs Turborepo for CI: Which Monorepo Tool Is Faster?
Both speed monorepo CI with task caching and affected-only runs; Nx is the heavier, plugin-rich platform while Turborepo is lighter and config-light.
Nx is a full-featured monorepo build system with generators, plugins, a task graph, and computation caching (local and remote). Turborepo is a lighter task runner focused on fast, cached pipelines with minimal configuration.
| Nx | Turborepo | |
|---|---|---|
| Scope | Full platform (plugins, generators) | Task runner + caching |
| Task/computation cache | Yes (local + remote) | Yes (local + remote) |
| Affected/only-changed runs | Yes (nx affected) | Yes (filtering) |
| Config weight | Heavier, more features | Lighter, minimal |
| Best for | Large, multi-language monorepos | JS/TS monorepos wanting simplicity |
In CI
Both cut CI time the same way: cache task outputs and run only the projects affected by a change, so unchanged packages are not rebuilt or retested. A shared remote cache across CI jobs is the single biggest speedup for either. Nx offers a richer platform (plugins, generators, language support) at more configuration weight; Turborepo is lighter and faster to adopt for JS/TS monorepos.
Speed it up
Enable the remote cache and persist it across CI runs, and scope tasks to affected projects. Both run on CI runners; faster managed runners shorten the tasks that still have to execute on a cache miss.
The verdict
Want a full monorepo platform with plugins and multi-language support: Nx. Want a lightweight, config-light cached task runner for JS/TS: Turborepo. Enable the remote cache and affected-only runs on either.
