Packwise

This tool does not just say “upgrade to the latest version.” It inspects the repository in the same places real upgrade failures usually hide: workspace scope, package manager signals, runtime pins, lockfiles, direct dependencies, CI workflows, Dockerfiles, deployment configuration, and source-level compatibility risks. In the Node lane, it uses fixed analysis steps such as discover_repo_scope, collect_runtime_evidence, inspect_dependency_blockers, inspect_ops_runtime, inspect_source_compatibility, and compare_target_paths. In the stack-aware lane, it can first detect whether the repo is plain Node, React, or another supported stack before choosing the right analysis path. The result is not a vague recommendation. It produces a structured modernization report with exact issues, evidence tied to files, a chosen upgrade path, ordered execution phases, validation commands, and a tool trace showing what was checked. If both direct and staged upgrades are possible, it scores the paths by risk and effort instead of forcing a guess. It also saves the report to reusable history files and opens a local viewer, so the upgrade plan becomes a shareable engineering artifact, not a one-time chat answer.
