RepoMind

Understand any codebase in seconds, not weeks.

RepoMind is an AI-powered repository exploration tool that loads entire codebases into Claude Opus 4.6's 1M token context window. Ask questions, get architecture diagrams, and truly understand any codebase instantly.

Features

• 1M Token Context — Entire codebases loaded at once, not fragmented chunks
• Adaptive Thinking — Claude Opus 4.6's extended thinking for deep reasoning
• Interactive Architecture Diagrams — Auto-generated diagrams showing module dependencies
• Streaming Responses — Watch reasoning happen in real-time with specific file:line references
• Multi-Viewport Ready — Responsive design works on desktop, tablet, and mobile

Demo

Coming soon! The live demo will be available once deployed to Cloudflare Pages.

Quick Start

Prerequisites

• Node.js 18+ or 20.x
• Anthropic API key (Get one here)

Installation

git clone https://github.com/X-Arc-ai/repomind.git
cd repomind

# Install dependencies
npm install

# Set up environment variables
cp .env.example .env.local
# Edit .env.local and add your ANTHROPIC_API_KEY

Development

npm run dev

Open http://localhost:3000 to see the app.

Production Build

npm run build
npm start

Usage

1. Load a Repository

   • Paste any public GitHub URL, or
   • Use quick-start buttons (Express, React, Next.js)

2. Ask Questions

   • "How does routing work?"
   • "Find security issues"
   • "Explain the architecture"

3. Generate Diagrams

   • Click "Generate" in the Architecture tab
   • Optionally specify a focus area (e.g., "routing system")

Deployment

Cloudflare Pages

1. Build Settings:

   • Build command: npm run build
   • Output directory: .next
   • Framework: Next.js

2. Environment Variables:

   • ANTHROPIC_API_KEY — Your Claude API key
   • NODE_VERSION — 20 (optional)

Other Platforms

RepoMind is a standard Next.js 16 app and can be deployed to any platform that supports Next.js:

• Vercel
• Netlify
• AWS Amplify
• Railway
• Self-hosted with Docker

Tech Stack

• Framework: Next.js 16 (App Router)
• UI: React 19, Tailwind CSS, shadcn/ui
• AI: Claude Opus 4.6 via Anthropic API
• Diagrams: React Flow
• Markdown: react-markdown with syntax highlighting

Architecture

RepoMind uses Claude Opus 4.6's 1M context window to load entire repositories:

1. Repository Ingestion — Clones the repo and loads all source files
2. Context Assembly — Builds a structured context document with file contents
3. Session Management — Maintains conversation state with full repo context
4. Streaming Responses — Uses Server-Sent Events for real-time output
5. Diagram Generation — Analyzes codebase structure and generates interactive visualizations
