24 alternatives to Google Maps but for your repo (Open Source)
Hi HN, I built Repomap, a tool that generates interactive architecture diagrams from any GitHub repository. It uses a Rust + tree-sitter engine to analyze the codebase and produces a D3-based graph UI with clustering, zoom/pan, and live progress updates

GitDiagram▲342GitDiagram is an open-source micro dev-tool that I made this past week Given any public GitHub repository it generates diagrams in Mermaid.js with Claude 3.5 Sonnet I extract information from the file tree and README for details and interactivity (you can click components to be taken to relevant files and directories) Also, you can replace "hub" with "diagram" in any repository URL to access its diagram I created this because I wanted to contribute to open-source projects but quickly realized their codebases are too massive for me to dig through manually, so this helps me get started I do…

What works now: user signups, org creations, private/public repos, and importing GitHub repositories (both as read-only mirrors and full migrations). So basically, you can create, push and pull to a repo, but we don't have many features quite yet (issues, PRs, CI). What is a bit unique is: 1) we built it in Rust and 2) the website is a little odd. Its design is inspired by CLIs (e.g., fzf, broot, vim) instead of web apps, and as such, lacks some affordances that you might typically expect in favor of keyboard-driven instant navigations (we have the very ambitious goal of an FCP of…

I built this as part of my quest to properly learn data visualization. The code is the easy part! Some lessons learned: - personal verification of the the general truth that pie charts are tough! and the returns are not great for the effort due to people's difficulties perceiving angles - may not use "vanilla" d3 with no React. was difficult to adapt for mobile - the GitHub API provides fairly standardized responses so building dynamic charts wasn't too bad. But when working with streaming data (say Kafka) I can see this getting interesting... schema registry should help but creating a view…

ProductMap AI▲160Hey 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?
