DependencyNecromancer

The Problem

Developers on HN and r/webdev frequently describe the specific dread of returning to a side project after 6–18 months and finding 47 outdated dependencies, broken peer requirements, and security advisories — the 'dependency graveyard' problem. DependencyNecromancer analyzes a repo's package.json or requirements.txt, groups upgrades by risk level (patch/minor/breaking), and generates a prioritized upgrade plan with one-click PR drafts for safe updates and annotated notes for breaking ones. Unlike Dependabot, it explains *why* each upgrade matters in plain language.

Target Audience

Solo developers and small teams maintaining multiple side projects or legacy codebases

Monetization Angle

Freemium — free for 1 repo, $10/mo for unlimited repos; $25/mo for team features

Recommended Tech Stack

Why Now

The explosion of AI-assisted side projects means developers are starting more repos than ever but maintaining fewer — creating a massive backlog of stale codebases that need revival.

MVP Scope

A CLI tool that reads package.json, calls npm audit and npm outdated, then outputs a Markdown upgrade plan sorted by risk with changelog summaries.

AI Angle

LLM reads changelogs and migration guides to generate a 2-sentence plain-English summary of what breaks and what to do about it for each major version bump.

Primary Risk

GitHub's Dependabot and Renovate are free and widely used — differentiation must be clearly felt in the UX within the first 60 seconds.

Validation Checklist

• Search HN 'Ask HN: How do you handle returning to old projects?' and count dependency-related complaints
• Post a poll in r/webdev: 'What's the worst part of reviving a dormant side project?' with dependency hell as an option
• Build a CLI MVP in Python that generates a risk-grouped upgrade report and share on r/Python and r/webdev
• Compare against Renovate's GitHub star growth rate to estimate market appetite for a friendlier alternative

Who Would Pay For This

Likely buyers are engineering teams, platform leads, developer-experience teams, and technical founders. Start with Solo developers and small teams maintaining multiple side projects or legacy codebases and look for teams already spending time or money on this workflow.

First 10 Users

Find the first 10 users by searching for recent complaints around "developer tools dependencies" in Hacker News, developer communities, GitHub issues, and niche Slack or Discord groups. Offer a concierge version first: manually solve the workflow for a few users, then automate only the repeated steps.
