# Nx vs Tuist: monorepo task runner and build infrastructure

Compare Nx and Tuist for monorepo builds, caching, running only what changed, and test reliability, and see where the two overlap and where they work at different layers.

## What is Nx?

[Nx](https://github.com/nrwl/nx) describes itself as a monorepo solution for TypeScript and polyglot codebases. It is open source under the MIT license, built in Rust, and extensible through TypeScript plugins. Nx builds a project and task graph for the workspace and runs the tasks your existing tools define. Its [computation cache](https://nx.dev/docs/features/cache-task-results) hashes each task's inputs and, on a hit, restores the task's terminal output and declared output files, whatever tool the task runs. [`nx affected`](https://nx.dev/docs/features/ci-features/affected) uses Git changes and task inputs to run only the tasks a change reaches. Plugins cover tools such as Vite, Webpack, Jest, Vitest, ESLint, Gradle, Maven, .NET, and Go. Nx Cloud adds [remote caching](https://nx.dev/docs/features/ci-features/remote-cache), [task distribution across machines](https://nx.dev/docs/features/ci-features/distribute-task-execution), [flaky task detection and retries](https://nx.dev/docs/kb/flaky-tasks), and an [MCP server](https://nx.dev/docs/reference/nx-mcp) for coding agents. Teams can also run their own remote cache server against Nx's [published OpenAPI specification](https://nx.dev/docs/kb/self-hosted-caching).

## What is Tuist?

Tuist is build infrastructure for engineering teams and coding agents: a shared environment where developers, CI, and coding agents build and test. It is not a CI provider, a CI runner, or a coding agent. Instead of running tasks itself, Tuist integrates with the build system a project already uses, such as Xcode, Gradle, Bazel, or Mix, and works through that build system's own model: Gradle task outputs, Bazel actions, Xcode compilation outputs, and Mix compilation and ExUnit results. See [build systems](https://tuist.dev/marketing-markdown/build-systems) for what each integration supports.

## Compare the responsibilities

| Criterion | Nx | Tuist |
| --- | --- | --- |
| Role | Task runner and monorepo tool: it discovers projects, orchestrates the tasks your tools define, and caches their results. | Build infrastructure behind your existing build system: shared caching, build and test insights, and agent access to that evidence. |
| Graph | Builds a project and task graph across the workspace, inferred by plugins or declared in configuration. | Uses the build system's own graph, such as Gradle tasks or Bazel targets. For Xcode, Tuist generated projects add an explicit project graph. |
| Caching | Hashes each task's inputs and restores its terminal output and declared outputs, locally and through a remote cache. | Backs each build system's native cache: [Gradle's build cache](https://tuist.dev/en/docs-markdown/guides/features/cache/gradle-cache), [Bazel's remote cache](https://tuist.dev/en/docs-markdown/guides/features/cache/bazel-cache), and [Xcode's compilation cache](https://tuist.dev/en/docs-markdown/guides/features/cache/xcode-cache). |
| Running only what changed | `nx affected` selects tasks whose inputs a change touches. | [Selective testing](https://tuist.dev/en/docs-markdown/guides/features/selective-testing) runs only affected test targets in Tuist generated Xcode projects. Elsewhere, the native cache skips work whose inputs have not changed. |
| Test reliability | Nx Cloud marks a task flaky when the same inputs both fail and pass, and retries it on another agent. Detection names the task, not an individual test. | [Test insights](https://tuist.dev/marketing-markdown/tests) track individual tests across runs, detect [flaky tests](https://tuist.dev/en/docs-markdown/guides/features/test-insights/flaky-tests), and support quarantine for supported build systems. |
| Agents and CI | Nx Cloud connects to existing CI providers. The Nx MCP server gives agents access to Nx Cloud pipelines and task monitoring. | Works with existing CI. The [Tuist MCP server](https://tuist.dev/en/docs-markdown/guides/features/agentic-coding/mcp) gives authorized agents the same build and test evidence that people see. |

The two tools work at different layers. Nx sits above the build tools and decides which tasks run and whether a whole task can be restored. Tuist sits inside the build system's own caching and reporting, so it can reuse outputs at the granularity that build system understands, such as individual Gradle tasks, Bazel actions, or compiled Swift files.

## Choose Nx when

Nx fits a JavaScript or TypeScript monorepo, or a polyglot workspace where one task runner should orchestrate many tools behind a single command and cache. Its plugin ecosystem, affected-task selection, and Nx Cloud CI features are designed for that job. Tuist does not run or orchestrate JavaScript or TypeScript tasks.

## Choose Tuist when

Choose Tuist when your builds run on Xcode, Gradle, Bazel, or Mix and you want shared caching and build and test evidence that follow that build system's own model, for developers, CI, and coding agents alike. Tuist does not replace your build system or your CI, and adoption starts with one supported integration. See the [documentation](https://tuist.dev/en/docs-markdown/guides/get-started) and [pricing](https://tuist.dev/marketing-markdown/pricing).

## Using both in a Gradle workspace

Nx can run Gradle projects through its `@nx/gradle` plugin, which registers Gradle projects in the Nx graph and runs their tasks through Gradle (see [Nx with Gradle](https://nx.dev/docs/technologies/java/gradle/introduction)). Gradle's build cache configuration still applies inside those Gradle runs, including a remote cache configured with the [Tuist Gradle plugin](https://tuist.dev/en/docs-markdown/guides/install-gradle-plugin). Nx's cache then works at the level of whole Nx tasks, while Gradle's cache works at the level of individual Gradle tasks. If you run both, measure the combination on your workspace before relying on it.

## First experiment

Pick one representative workflow, such as a Gradle module's build and tests. Record a clean run, a repeat run on a second machine, and the time spent investigating a failure. Add one Tuist capability, for example the [Gradle cache](https://tuist.dev/en/docs-markdown/guides/features/cache/gradle-cache) or [Gradle test insights](https://tuist.dev/en/docs-markdown/guides/features/test-insights/gradle), keep the workload comparable, and compare feedback time, total machine usage, and what an engineer and an authorized agent can learn from the recorded results.

## Frequently asked questions

### Is Nx a build system?

Nx orchestrates and caches tasks that other tools define, such as a bundler, a test runner, or Gradle. The underlying tool still does the compiling and testing. Tuist also builds on existing build systems instead of replacing them, but it integrates with their native caches and reports rather than running tasks itself.

### Does Tuist support JavaScript or TypeScript monorepos?

Not as a task runner. Tuist does not run or orchestrate JavaScript or TypeScript tasks; its integrations target build systems such as Xcode, Gradle, Bazel, and Mix. Once, a build tool that can wrap commands such as `npm run build` and use Tuist for remote caching, has a Tuist integration in canary. For orchestrating and caching JavaScript or TypeScript tasks across a workspace, Nx is designed for that job.

### Can I use Nx and Tuist together?

In a Gradle workspace, yes. Nx runs Gradle tasks through Gradle, so a remote build cache configured with the Tuist Gradle plugin still applies inside those runs. Measure the combination on your workspace before relying on it.

### How do the caches differ?

Nx caches whole tasks: when a task's inputs match a previous run, it restores the task's terminal output and declared output files. Tuist backs each build system's own cache, so reuse happens at that build system's granularity, such as individual Gradle tasks, Bazel actions, or Xcode compilation outputs.

### Do I need to change CI to adopt either tool?

No. Nx Cloud connects to CI providers such as GitHub Actions and GitLab, and Tuist works with the CI you already use.
