## Detailed Description

NetPulse — The network tab that thinks.

A powerful, zero-config developer tool that captures all API traffic from any browser tab and gives you AI-powered insights — without leaving your browser.

### WHAT IT DOES

• Captures every HTTP request with headers, body, timing, and status
• Intercepts full response bodies from fetch and XHR calls
• Analyzes your traffic with AI — detects patterns, anomalies, and performance issues
• Generates an API Health Score (0-100) with actionable recommendations
• Scans for security vulnerabilities (tokens in URLs, missing HTTPS, exposed data)
• Maps which page sections are powered by which APIs (UI Data Map)
• Provides ready-to-use AI prompts for design, testing, debugging, and deployment

### KEY FEATURES

→ Request Replay: Edit and re-send any captured request
→ CORS Detector: Identifies issues with server fix suggestions
→ Security Scanner: Finds vulnerabilities in your API traffic
→ Dependency Map: Visualizes API call chains as sequence diagrams
→ JWT Decoder: Decode tokens from Authorization headers
→ Code Generator: JavaScript, Python, C#, Java, Go, PHP, Ruby, Playwright
→ OpenAPI Spec & Postman Collection export
→ Response Diff: Compare two responses side by side
→ API Mocking: Return custom responses for matched URLs
→ Full-text search across all captured data
→ Data Model (ERD) generation with Mermaid export
→ Dashboard Suggestions with Fluent UI component references
→ AI Prompts Library with 16+ ready-to-use developer prompts
→ Over-Fetching Analysis: See how much data is fetched vs used
→ Third-Party Risk Map: Track external service dependencies
→ Data Freshness: Audit cache headers across all responses
→ Page Weight Budget: Monitor total API payload size

### THREE THEMES

☀️ Light • 🌙 Dark • 💎 Glass

### PRIVACY FIRST

All data stays in your browser. Nothing is transmitted externally. No accounts, no tracking, no cloud. Works completely offline.

### WHO IS THIS FOR

• Frontend developers debugging API integrations
• Backend developers testing endpoints
• QA engineers validating API contracts
• Security engineers auditing CORS and auth flows
• Anyone who wants to understand what their web apps are doing under the hood
