Turborepo

Turborepo is Vercel's open-source build system for JavaScript and TypeScript monorepos. It models your workspace as a task graph of builds, tests, and lint jobs, then runs them in the right order with maximum parallelism while skipping anything whose inputs have not changed, thanks to content-aware caching. Remote caching lets a whole team and CI share cache artifacts, so a build that ran on a teammate's laptop never reruns on yours.

Turborepo 2.x refined the configuration format and added features like package-scoped task configuration and a watcher mode. It plugs into your existing package manager (npm, pnpm, yarn, or Bun) rather than replacing it, which is why adoption skews toward teams that already have a monorepo and want faster CI without a rewrite. The project is MIT-licensed, maintained by Vercel, and widely used across the Next.js ecosystem.

Install per-workspace with npm install turbo --save-dev, add a turbo.json defining your task pipeline, then run turbo run build.
