PViz Generator

Hey Product Hunt! I'm Mike, and I built PViz Generator after spending way too many hours trying to understand unfamiliar codebases. The problem: You inherit a codebase or join a new team. You have two bad options: 1️⃣ Spend days reading files — You go down rabbit holes, lose context, and still don't understand the architecture 2️⃣ Ask ChatGPT — It confidently explains code... using file paths that don't exist and architecture that was deprecated 6 months ago What PViz Generator does: Instead of guessing, the repository is analyzed structurally and you are provided a detailed output laying out: 📊 Dependency graphs — See which files import which, what's central vs peripheral 🏗️ Architectural zones — Automatically grouped into logical areas (API, database, business logic) 🔗 Coupling metrics — Which files are risky to change (imported by 30+ others) 🔄 Circular dependencies — Found automatically (Module A imports B imports A) This output can then be used by you or your team to develop a full picture of the entire codebase or fed directly into a LLM to establish grounding context which allows question to generate more reliable answers. Questions like — "Where is authentication implemented?" "What depends on the database module?" Why I built this: I was tired of: Loosing my mental model of the codebase as it grew to be too large AI tools confidently hallucinating about code they've never analyzed Having no idea what would break when I changed something PViz gives you the architectural map first, then you can explore with context. Current state: ✅ Supports Python, JavaScript, TypeScript, Go, Java ✅ Works with public and private repos ✅ Free trial (3,000 tokens + 4 weekly analysis credits) ✅ Token-based pricing with upfront estimates Who it's for: Developers joining new teams (get oriented in hours, not weeks) Tech leads doing code reviews (see coupling and dependencies) Consultants doing due diligence (evaluate codebases quickly) Anyone inheriting legacy code (understand before you change) Want a full walkthrough? I recorded a detailed 10-minute demo during development [https://youtu.be/2VaiEE_8JxI] Happy to answer any questions! And if you have a codebase you're struggling to understand, I'd love for you to try PViz and let me know what works (or doesn't). Thanks for checking it out! 🚀
