Nx

Nx is an open-source, technology-agnostic monorepo build platform from Nrwl (backed by a16z) that speeds up builds and CI through computation caching, task orchestration, and running only the projects affected by a change. Its developer surface spans a local CLI (nx) with a large family of first-party @nx/* technology plugins and code generators, an official Model Context Protocol server (nx-mcp) and Nx Console editor integrations for AI-assisted development, and the hosted Nx Cloud service for remote caching, distributed task execution (Nx Agents), and self-healing CI. Nx is a build/CI tooling platform rather than a REST API provider — its integration surface is the nx CLI, the @nx/* npm packages, the MCP server, and Nx Cloud.

Nx is profiled on the APIs.io network. Tagged areas include Company, Build System, Monorepo, Developer Tools, and CI/CD.

Nx’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 16 more developer resources.
