DepAudit: Python Dependency Migration & Feature Audit Tool
A CLI tool that analyzes Python project environments before updates or migrations, detects silently carried-over features and dependencies from legacy environments, and provides a clear diff report of what will change. Prevents unexpected build triggers from features that were enabled in prior environments but never explicitly opted into.
Why this matters
You update your Python project to a new version. Unknown to you, the update process silently carries over optional features from your previous environment — features you never explicitly enabled and may not even use. One of those carried-over features triggers a source build for a C extension that fails because of a missing compiler. You spend hours wondering why an update is trying to build a package for a feature you thought was disabled. Even your plugins.disabled list is ignored. There is no audit trail showing what was carried over and why, leaving you to reverse-engineer the migration logic yourself.
- · Built for Developers and DevOps teams managing Python projects with complex feature flags, optional dependencies, or environment migrations where legacy state silently carries over.
- · Most likely monetization: freemium.

- Launch on GitHub and Python developer communities
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1The problem of silent feature carry-over may be specific to certain frameworks (like Hermes) rather than a general Python ecosystem issue, limiting the addressable market.
- 2Upstream tools may add migration audit features natively, making a standalone tool redundant.
- 3Developers may not perceive this as a problem worth paying for until they experience a costly failure, making adoption slow.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Four commenters identified that matrix/encryption features were silently carried over from legacy environments during updates. One noted that even explicit plugin disable lists were not respected for dependency resolution. Another discovered matrix was enabled by default rather than opt-in. The pattern of silent feature migration causing unexpected build attempts was consistent across multiple hosts and suggests a broader problem with Python environment migration transparency.
