Introducing Dependency Tree Visualizer: See Your Package Dependencies Like Never Before

If you've ever tried to understand the dependency tree of a large Node.js project, you know the struggle. Running npm list gives you a wall of text. The package.json only shows top-level deps. And good luck spotting security vulnerabilities or deprecated packages in the mix.

That's why we built Dependency Tree Visualizer—an interactive, browser-based tool that transforms your package.json into a beautiful, security-aware tree that reveals everything you need to know about your dependencies.

The Hidden Complexity Problem

Modern JavaScript projects are dependency juggernauts. A typical React app can easily have:

1,000+ packages in node_modules
Complex nested relationships 5+ levels deep
Multiple versions of the same package
Security vulnerabilities hiding in transitive deps
Deprecated packages slowly rotting your codebase

Traditional tools show you lists. We show you the relationships, risks, and structure that actually matter.

Enter Dependency Tree Visualizer

Dependency Tree Visualizer is a free, privacy-first tool that turns your package.json into an interactive map of your project's dependencies:

🌳 Interactive tree visualization with expand/collapse navigation
🚨 Security vulnerability detection for known CVEs
⚠️ Deprecated package warnings (moment, request, etc.)
📊 Dependency statistics and health metrics
🎨 Color-coded types (production, dev, peer, optional)
🔒 100% browser-based - your data never leaves your device

Key Features That Matter

Stop squinting at text output. Our interactive tree lets you:

Click to expand/collapse branches
See dependency relationships at any depth
Navigate complex trees with ease
Focus on specific branches without distraction

Each dependency is color-coded:

🔵 Production (Blue) - Runtime dependencies
🟣 Development (Purple) - Dev-only tools
🟢 Peer (Green) - Expected by consuming projects
⚫ Optional (Gray) - Nice-to-have packages

🚨 Security Intelligence

Don't ship vulnerabilities. Our analyzer checks for:

Known CVEs in popular packages
Deprecated packages that need replacement
Version conflicts and wildcard warnings
Security severity scores

See issues highlighted in red (critical) and yellow (warnings) right in the tree.

📊 Instant Statistics

Get project insights at a glance:

📦 Total Dependencies: 847
   🔵 Production: 23
   🟣 Development: 156  
   🚨 Security Issues: 3
   ⚠️ Deprecated: 7

Perfect for audits, reports, and quick project health checks.

🔒 Privacy by Design

Your package.json contains sensitive information—internal package names, versions, architectural decisions. That's why:

Everything runs in your browser via JavaScript
No uploads to our servers ever
No data logging or analytics on your deps
Works offline once loaded
Safe for proprietary projects

Real-World Use Cases

🔍 Security Auditing

Before deploying that critical update:

Upload your package.json
Scan for red vulnerability markers
Prioritize fixes by severity
Document security posture for compliance

📈 Technical Debt Assessment

Understanding what needs updating:

Spot deprecated packages like moment.js
Find duplicate dependencies inflating bundle size
Plan migration strategies with visual context
Communicate complexity to stakeholders

👥 Team Onboarding

New developers joining the project:

Visual project structure beats reading lists
Understand architectural decisions at a glance
See dependency relationships and why they exist
Learn codebase complexity before diving in

🏢 Enterprise Compliance

For teams that need dependency governance:

Audit third-party packages for license compliance
Track security posture across projects
Document dependency decisions with visual evidence
Share reports with security teams

How It Works

Dead simple. No signups. No configuration:

📁 Upload your package.json file (or paste the content)
🔍 Analyze - We parse dependencies in milliseconds
🌳 Explore - Click through the interactive tree
📋 Export - Save insights or share with your team

Built for Modern Development

Dependency Tree Visualizer uses cutting-edge web technology:

Next.js 16 with App Router for performance
TypeScript for reliability
Tailwind CSS for responsive design
Radix UI for accessibility
Framer Motion for smooth interactions
WebAssembly for fast parsing of large files
