Our verdict on affected
affected is an open-source, standalone command-line tool for monorepos. It detects project ecosystems, builds dependency graphs from project manifests, compares Git changes, and identifies packages affected directly or through dependencies. Teams can use it to run tests, builds, linting, or arbitrary commands only where changes require attention. Its ecosystem coverage includes Cargo, npm, pnpm, Yarn, Bun, Go, Python, Poetry, uv, Maven, Gradle, .NET/C#, Swift/SPM, Dart/Flutter, Elixir/Mix, and Scala/sbt, making it suited to repositories that span more than one language or package manager.
The main strength is affected-task depth. affected provides dependency-chain explanations, parallel command execution, file watch mode with debouncing, and automatic project ecosystem detection. Its CI output supports GitHub, GitLab, CircleCI, Azure Pipelines, and generic environments, while JSON and JUnit formats help connect results to existing workflows. GitHub Actions setup and pull-request comment integrations add a direct review workflow, and Graphviz support can help visualize dependency relationships. This makes the tool a practical fit for teams that need to understand why a package is affected, not only which package changed.
The trade-off is scope. affected concentrates on detecting impacted packages and running relevant commands; it does not provide verified caching or workspace boundary controls. Its standalone CLI distribution through package managers, Homebrew, GitHub Actions, and releases gives teams several installation paths, but the product remains centered on command selection rather than a broader monorepo management suite. Choose affected when transitive impact analysis, multi-ecosystem support, CI output, and dependency explanations matter most. Consider another tool when verified caching or explicit workspace boundaries are required.
