GRID Analyzer

Understand any codebase in minutes with local-first AI

GRID Analyzer is a privacy-first command-line tool that uses local AI models to help you understand unfamiliar codebases. Index, query, and visualize relationships—all without sending your code to external APIs.

✨ Features

• 🔒 Privacy-First: All analysis happens locally. Your code never leaves your machine.
• 🚀 Fast Indexing: Analyze large codebases (100K+ files) in minutes
• 💬 Natural Language Queries: Ask questions in plain English
• 🗺️ Visual Mapping: Generate interactive relationship graphs
• 🎯 Pattern Detection: Automatically detect architectural patterns
• 🔍 Multi-Language Support: Python, JavaScript, TypeScript, Java, C++, Go, Rust, and more
• 📦 Zero Configuration: Works out of the box

🚀 Quick Start

Installation

pip install grid-analyzer

Running GRID Analyzer

Option 1: Direct command (recommended)

grid --help
grid analyze /path/to/codebase

Option 2: Python module (if grid command not found)

python -m grid_analyze_cli --help
python -m grid_analyze_cli analyze /path/to/codebase

Note: If the grid command isn't found, ensure Python's Scripts directory is in your PATH, or use the python -m grid_analyze_cli syntax which always works.

Basic Usage

# 1. Index your codebase
grid analyze /path/to/codebase

# 2. Ask questions
grid query "Where is user authentication handled?"
grid query "What files connect to the database?"
grid query "How does the payment system work?"

# 3. Generate visual map
grid map --output relationships.html
