Nx

Nx builds developer tools for teams managing related software projects in a shared repository. Its open-source Nx platform maps project relationships, coordinates tooling through plugins, and reuses cached task results. Nx Cloud extends that workflow with shared remote caching and Nx Agents, which distribute CI tasks across machines. Its Self-Healing CI diagnoses failures and proposes fixes for developers to review, with optional automatic application of high-confidence fixes.

Jeff Cross and Victor Savkin founded the company in 2016 after leaving Google, releasing Nx in 2017 to support monorepo development for large software teams. Its approach combines knowledge of project dependencies and task timings to distribute build work. In 2026, the team introduced Polygraph, an agent-agnostic product that connects repositories into a dependency graph without moving code. It also preserves session history so engineers and agents can resume work across machines and coordinate changes spanning multiple repositories.

Nx pairs its open-source platform with free, paid team, and custom enterprise Nx Cloud plans. Enterprise options include isolated or self-hosted deployment, cross-repository visibility, and organizational conformance checks. In 2026, the company reported more than 3.5 million developers using Nx daily—a measure of adoption rather than paying customers.
