RepoViz

An interactive GitHub repository visualizer. Paste a public repo URL and RepoViz turns it into a node-based graph of the project's file structure, dependencies, and tech stack.

Features

• Generates a graph from a public GitHub repository URL
• Shows folders, files, languages, and dependencies as connected nodes
• Toggle individual files, folders, and dependencies on or off from the sidebar
• Customize the graph layout and appearance
• Export diagrams for documentation or team sharing

Tech stack

React 19 · TypeScript · Vite · D3 · Google Gemini (@google/genai)

Run locally

Prerequisites: Node.js 18+ and a Gemini API key

git clone https://github.com/deaneeth/RepoViz.git
cd RepoViz
npm install
echo "GEMINI_API_KEY=your-key" > .env.local
npm run dev

Other scripts: npm run build for a production build, npm run preview to serve it locally.

Notes

The Gemini key is injected at build time by Vite, so don't deploy a build that contains a key you want to keep private.
