Create diagrams of complex data flows in software systems▲205
Hello HN, It has been a while since I contributed to the web, so I decided to get back in shape and publish "something". This app is a POC of "what if diagrams were more dynamic". I'm a software engineer by trade, and with conventional tools, I often times struggle to explain flows of data in complex software systems. I got inspired by video games like The Incredible Machine and Factorio, as in some ways, software systems tend to become Rube Goldberg-esque machines ;) As a side quest, I also wanted to craft diagrams faster than text-based tools (ex: mermaid), as I am always forgetting their…

ProductMap AI▲160
Hey HN, I built ProductMap AI, a tool that automatically identifies features implemented in source code and organizes them in a visual hierarchy. The goal is to help developers quickly understand poorly documented codebases. Link: https://product-map.ai/ I’d love feedback from the HN community! Let me know what you think. Would this be useful for you?

Noodles – Explore AI-generated codebases through interactive diagrams▲10
I built Noodles to help me keep up with the codebases my AI tools generate. Open sourced last week, hit 400 stars in 8 days. The problem: AI assistants scaffold entire features quickly, but leave you maintaining code you didn't write. When bugs appear, you're reverse-engineering your own project. Noodles generates interactive D2 diagrams showing execution flow: - Scans the repository and identifies entry points (CLI commands, routes, UI components) - Maps how execution flows from entry to outcome - Renders interactive overlays with clickable nodes and tooltips - Updates incrementally when…

Codeflowmap – map a codebase's read/write/auth data flows▲7
I've been vibe-coding tools to automate chunks of my consulting work, fell down a rabbit hole, and started building actual products. Suddenly I'm in a world of unknown-unknowns and known-unknowns. One of the bigger things to solve was understanding code the LLM generated that I didn't fully grasp. What does it touch? What reads and writes where? Is the auth path where I think it is? So I built codeflowmap. Point it at a repo and it maps the dependency and call graph, then surfaces the read / write / auth paths between files and functions. Connect a local model (Ollama) or any…

Stage CLI – An easier way of reading your AI generated changes locally▲46
Hey HN! We're Charles and Dean. A few weeks ago we posted about Stage, a code review tool that guides you through reading a PR step by step - https://news.ycombinator.com/item?id=47796818. We got a lot of great feedback but also heard from many people that they wanted to have the chapters experience even before opening a PR… so we built the Stage CLI as the local, open-source version that anyone can try. Here’s a quick demo video: https://www.tella.tv/video/stage-cli-demo-f55q It works with any coding agent of your choice. The skill instructs the agent to…
