Ultra Runner is a fast monorepo script runner and build tool for JavaScript/TypeScript projects. It detects existing lerna, yarn, npm, and pnpm workspaces, runs scripts in parallel with dependency awareness, and only rebuilds packages when files change.

Use cases

• run npm scripts across a monorepo in parallel
• incrementally rebuild only changed packages in a workspace
• replace lerna or yarn workspaces script running with something faster
• speed up npm run, yarn, and npx command execution
• run a script recursively in all packages that define it
• monitor and zoom output of concurrent build commands

When to choose

• you have a lerna, yarn, npm, or pnpm monorepo and want faster builds
• you want zero-config, non-intrusive parallel script execution
• you need dependency-aware concurrent builds with incremental rebuilds

When to avoid

• you need a full monorepo manager with publishing and versioning like lerna or nx
• your project is a single package with no workspaces
• you rely on tooling deeply integrated with a specific package manager's runner
