## What it is
Turborepo is a high-performance build system and task runner for JavaScript and TypeScript monorepos, written in Rust by Vercel. It parallelizes and schedules tasks across workspaces and uses local and remote caching so builds, tests, and lint runs are never repeated across machines or CI.

## Use cases
- speed up builds in a javascript monorepo
- cache task outputs across ci machines
- run build, test, and lint tasks in parallel across workspaces
- migrate an existing repo to a monorepo incrementally
- give coding agents fast feedback loops on their changes
- avoid rebuilding unchanged packages in ci

## When to choose
- you maintain a JavaScript/TypeScript monorepo with many packages and slow CI
- you want incremental adoption using existing package.json scripts and npm/yarn/pnpm
- your team wants shared remote caching to eliminate redundant work
- you use coding agents and want fast, scoped validation of changes

## When to avoid
- your project is a single small package with trivial build times
- you need a polyglot build system beyond the npm ecosystem (consider Bazel)
- you rely on non-package.json-based build tooling that turbo cannot orchestrate
