What pacwich is

pacwich is free, open-source monorepo tooling for Bun, npm, and pnpm workspaces. It orchestrates package.json scripts across workspaces in parallel or series, and its CLI can list workspaces, scripts, and tags or display workspace and script metadata. A TypeScript API offers affected-workspace capabilities alongside the CLI. By default, affected detection compares changes with a configured base reference and includes uncommitted changes. The verify feature analyzes JavaScript and TypeScript files for workspace imports or exports that lack dependency declarations. Configuration is optional and can be stored in JSON, TypeScript, JavaScript, or package.json files; documentation says setup requires no configuration. Pacwich provides AGENTS.md context files, agent skills, an MCP server, and an /llms.txt documentation index. It installs locally or globally through Bun, npm, or pnpm and requires a package-manager lockfile for workspace data. Linux and macOS are primary supported systems. Windows cmd.exe support has the lowest stability priority, and WSL is encouraged. A browser demo runs a project but omits several CLI capabilities.

Who it suits

pacwich suits developers maintaining monorepos with Bun, npm, or pnpm workspaces. It is useful for coordinating scripts, checking workspace boundaries, and detecting affected packages.

What it does well

Runs workspace scripts in parallel or series
TypeScript API accompanies the CLI
Detects affected workspaces by git changes
Verifies undeclared workspace dependencies
Core features remain free

What to know first

Requires a package-manager lockfile
Windows cmd.exe has lowest stability priority
Browser demo lacks git-based affected diffs

Verdict

pacwich provides free tooling for workspace orchestration, inspection, and dependency-boundary checks. Linux and macOS users get the primary support path, while Windows users may prefer WSL.
