Nx

Nx is a build system for JavaScript and TypeScript monorepos, with plugins that extend its task and code tools to other languages. It builds project and task graphs, orders work by dependencies, and runs tasks in parallel when possible. Nx Core provides local caching; Nx Cloud adds shared remote caching for teams and CI, and can distribute work across Nx Agents using task CPU and memory use. Plugins can infer tasks, generate or modify code, update dependencies, and provide executors. Documented integrations include Angular, React, Vue, Node.js, Java, .NET, Vite, Webpack, Rspack, Jest, Cypress, and Playwright. CI workflow setup is available for GitHub, CircleCI, GitLab, Azure Pipelines, Jenkins, and Bitbucket Pipelines. Nx Cloud describes controls for trusted-branch cache writes, artifact traceability, and invalidating artifacts made with revoked tokens. API communications are encrypted in transit, and task artifacts can be encrypted end to end before remote caching. Nx offers a free Hobby plan and a Team plan for $29/month; the Hobby plan's cloud features stop when monthly credits run out.

Nx combines task scheduling, caching, and code-generation tools for monorepo work. Hobby is free, while Team starts at $29/month with additional listed usage charges.

Nx suits developers and teams managing JavaScript or TypeScript monorepos, including individuals and small teams exploring Nx Cloud through Hobby. Its plugins and documented integrations also cover projects using other languages and development tools.

Overview

Nx is a build system for JavaScript and TypeScript monorepos, extended to other languages through plugins. It suits teams coordinating many projects and CI tasks in one repository; its strongest advantage is bringing dependency-aware builds, caching, and code generation together.

Founded in 2016 by former Googlers Jeff Cross and Victor Savkin, Nx spans build automation, monorepo management, and code generation. See Build Automation Software, Monorepo Management Tools, and Code Generators.

Key features

• Dependency-aware execution: Nx maps projects and tasks into graphs, respects dependencies, and parallelizes independent work where possible. This is useful when a monorepo’s build steps need coordination rather than being run as unrelated commands.
• Local and remote caching: Nx Core includes local caching; Nx Cloud adds a cache shared across a team and CI. The shared cache extends the benefit beyond an individual developer’s machine, but Cloud usage is capped or billed according to plan.
• Distributed CI: Nx Cloud distributes tasks across Nx Agents and packs them dynamically according to CPU and memory needs. That is aimed at CI workloads with varying task demands, rather than teams seeking only a local build tool.
• Generation and migrations: Plugins can infer tasks, generate or modify code, update dependencies, and provide executors. This connects routine project changes with the build system, though the value depends on using its plugin ecosystem.
• Broad integrations: Nx documents support for Angular, React, Vue, Node.js, Java, .NET, Vite, Webpack, Rspack, Jest, Cypress, Playwright, and other tools. It also offers CI workflow setup for GitHub, CircleCI, GitLab, Azure Pipelines, Jenkins, and Bitbucket Pipelines.
• Cloud security controls: Nx Cloud describes trusted-branch cache writes, artifact traceability, and automatic invalidation of artifacts made with revoked tokens. API communications are encrypted in transit, and task artifacts can be encrypted end to end before remote caching.

Pricing

Hobby: Free forever, with 50,000 credits reset monthly, 5 contributors, 10 concurrent CI connections, and community support. It fits individual developers and small teams exploring Nx Cloud. Once monthly credits run out, Cloud features turn off until the next reset, making this a constrained choice for sustained or heavier CI use.

Team: $29/month, including $29 in usage credit. Additional credits cost $5.50 per 10,000; contributors cost $19 each, and concurrent CI connections cost $2.25 each. Email support is included. The plan is a step up for teams that need shared Cloud capabilities, but its usage and seat-related charges can raise the bill beyond the starting price.

Enterprise: Custom pricing. It includes complete feature access, dedicated support and SLAs, isolated or self-hosted deployment, and SSO/SAML. This is the fit for organizations that require those deployment or support controls rather than a fixed-price entry tier.

A free trial is available. The published Team billing term is monthly; Hobby is free forever. Nx Core’s local cache is part of the product, while remote caching and distributed CI are Nx Cloud capabilities.

Platforms

Nx supports Linux, macOS, Windows, web, and self-hosted use. Its build-caching and remote-execution capabilities suit multi-platform workflows, while dependency locking is not a supported capability.

Who it's for

Nx is strongest for JavaScript and TypeScript teams managing multiple projects in a monorepo, particularly when shared caching, distributed CI, and plugin-driven code changes matter. Plugin support for other languages broadens its reach. A developer seeking only a free build tool without Nx Cloud’s usage caps or team charges may find its broader workflow unnecessary.

Pros and cons

Pros

• Builds account for dependencies: Task graphs order work and allow parallel execution where possible, which suits multi-project repositories.
• Caching extends to CI: Nx Cloud shares remote artifacts across teams and CI, beyond Nx Core’s local cache.
• Generation and migration live alongside builds: Plugins can handle code changes and dependency updates as well as task execution.
• Cloud controls address artifact trust: Trusted-branch writes, traceability, invalidation, and end-to-end artifact encryption offer useful safeguards for shared caches.

Cons

• Hobby Cloud access has a hard monthly ceiling: Cloud features stop when 50,000 credits are exhausted.
• Team costs can stack: The $29/month base includes only $29 in usage credit; additional credits, contributors, and concurrent CI connections have separate charges.
• No dependency locking: Teams needing that build capability will have to look elsewhere or use another approach.

Alternatives

• Xmake is a free option with support for Android and iOS as well as desktop platforms; consider it when those platforms matter more than Nx’s monorepo and Cloud workflow.
• Bazel is Google’s free, open-source build and test tool; choose it if that open-source tool is a better fit than Nx’s paid Cloud tiers.
• Open Build Service is free software licensed under GPL, with a reference server for open-source developers and self-hosted installation; consider it for that model.
• SCons is free under the MIT license, which permits use, modification, or redistribution without charge; it suits readers who prioritize those terms.
• Apache Maven is free under Apache License 2.0 and requires JDK 8+ for Maven 3.10; consider it when that Java build tool and licensing fit your needs.
• Buck2 is Meta’s free, open-source build system; it is an alternative for readers seeking that project.
• Gradle offers a free, open-source build system; consider it if that is the scope you need.
• Meson is a free, open-source build system for readers seeking that option.

Verdict

Choose Nx if your team needs dependency-aware monorepo builds and wants caching, distributed CI, and code-generation workflows in one system. Its main draw is the breadth of that integrated workflow; look elsewhere if dependency locking is essential or if Nx Cloud’s credit, contributor, and CI-connection charges do not suit your budget.
