Description
Analyze any GitHub repository with interactive visualizations, dependency analysis, and smart insights. Navigate codebases faster. Visualize any GitHub repository as an interactive graph. Find files instantly, analyze dependencies, detect security issues, and understand codebases 10 times faster than browsing folders. WHAT IT DOES GitNav transforms GitHub repositories into interactive force-directed graphs where you can drag, zoom, and click to explore. Each node represents a file, color-coded by type. Click any file to open it on GitHub, or click folders to zoom into specific sections. The smart search feature lets you find any file across the entire codebase with fuzzy matching, filtering by category, file type, or size. Results appear in real-time as you type. Comprehensive dependency analysis works across 7+ languages including JavaScript, Python, Rust, Go, Flutter, Java, and more. Instantly see which packages are outdated, detect heavy dependencies, and get suggestions for lighter alternatives. Security scanning identifies vulnerabilities, detects exposed secrets like API keys or passwords, and provides actionable recommendations to fix issues. All analysis happens locally in your browser with zero external servers. PERFECT FOR Learning from open source projects and understanding unfamiliar codebases Preparing for technical interviews by analyzing company repositories Conducting code reviews and security audits efficiently Onboarding to new projects and finding your way around large codebases Contributing to open source by quickly locating relevant files Evaluating project health and architecture before adoption KEY FEATURES Interactive Visualization Force-directed graph with drag, zoom, and pan controls. Color-coded nodes by file type. Hover for file details including name, size, and path. Supports repositories up to 60 files in the graph view with smooth animations. Smart File Search Fuzzy search across all files with filters for category, file type, and size. Shows up to 30 real-time results. Click any result to open the file directly on GitHub.
