Promote your LLM from Junior Dev to Chief Architect

AI-powered coding assistants can edit files, but they’re blind to the bigger picture – they don’t understand how your entire codebase fits together. Nx changes that.

With full visibility into your monorepo’s project relationships, dependencies, and ownership, Nx enables your LLM to move beyond local file changes to make informed architectural decisions. Future-proof your development with system-wide intelligence, not just AI-friendly tools.

Cross-stack reasoning

How does this frontend change impact our backend services?

Finally! CI that works for monorepos.

Current CI systems are slow, hard to maintain, and unreliable. With Nx Cloud, we introduce an innovative task-based approach to making CI for monorepos not just fast, but also cost-efficient. It plugs right into your existing CI setup, enabling features such as remote caching, dynamically allocating machines to distribute tasks, providing fine-grained e2e test splitting and automated flakiness detection. All with a single line of code!

Powerful and elegant UI

An application built for monorepo CI, so you can quickly find what failed, debug and move on.

Enable faster CI with a single line of code

AI for your CI

Identify and resolve task failures instantly with intelligent explanations and actionable solutions. Set your desired CI run time, and Nx Cloud will match it. Our custom AI model analyzes your previous runs, then dynamically predicts and allocates the optimal number of agents. The more you use it, the smarter it gets. Take the guesswork out of your work.

Collaborate better. Achieve more. Ship faster.

Tangled codebases without well-defined ownership crush the velocity of teams and the quality of products. Nx is the solution. By defining project boundaries, developers ensure code stays modular and easy to maintain. By using Nx plugins and code generation , developers standardize on best practices and reduce duplication. Plus, they keep everything up-to-date by using Nx's automated updating mechanism.

Try Nx for yourself

From overwhelming...

...to structured with clear ownership.

Smarter tools for your monorepo.

Nx plugins are like VSCode extensions, but for your Nx workspace. Imagine your tools being automatically detected, with caching, task distribution, and task splitting being pre-configured for you. All in sync with your underlying tooling configuration. Plus there are code generators and utilities to help you integrate your favorite technologies, making working in a monorepo a much more pleasant experience.
