Our verdict on pacwich
pacwich is an open-source monorepo tool for JavaScript and TypeScript projects using Bun, npm, or pnpm workspaces. It targets teams managing small package.json monorepos that need workspace visibility, coordinated scripts, affected-package execution, and dependency rules without adding configuration for basic use. The tool runs locally in a project and offers both a command-line interface and a TypeScript API, with shell completions for CLI workflows.
Its core workflow covers several practical monorepo tasks. pacwich can inspect workspace metadata, run package.json scripts in parallel or in dependency order, and detect affected workspaces from Git changes before executing targeted scripts. It also verifies workspace dependencies and supports configurable allow and deny rules, giving maintainers a way to define package-boundary policies. Integration with Bun, npm, pnpm, and Git fits projects already using those tools, while the published platform support includes Windows, macOS, Linux, and an API.
The product is distributed under the MIT License and is positioned as a focused local utility rather than a paid platform with multiple service tiers. That makes it a practical choice for teams that want open-source tooling around workspace inspection, task ordering, affected builds, and dependency governance. Teams needing a broader monorepo platform should evaluate whether its focused package-manager support and local operating model match their workflow. pacwich is most suitable when the repository already uses package.json workspaces and the main requirement is dependable coordination of package scripts and dependencies.
