  # Network++: Advanced API Inspector & DevTools Extension
  Supercharge your Chrome DevTools with Network++, the ultimate API inspection and debugging tool for modern web development. Native support for GraphQL, JSONPath querying, and Postman-style collections directly in your browser.
  
  Whether you are debugging complex GraphQL queries, inspecting REST APIs, or extracting data with JSONPath, Network++ provides the developer tools you actually need without the bloat.
  
  ### 🚀 Core Features
  - Advanced Request Capture: Automatically intercepts and logs XHR, Fetch, and GraphQL requests (including both GET and POST). Captures retroactively even before the panel is opened.
  Interactive JSON Viewer & JSONPath: Click on any value in a JSON response to instantly generate robust JSONPath queries. Test JSONPath expressions live with our custom CSP-safe evaluation engine.
  - Edit & Replay APIs: Easily modify any captured request's headers, body, or URL and instantly resend it. Perfect for rapid API testing without switching tools.
  - Saved Collections (Postman Alternative): Save your most important requests and responses into organized, persistent folders. Load them back up across DevTools sessions to test and replay later.
  - Intelligent Search & Filtering: Filter traffic effortlessly by type (All, XHR, Fetch, GraphQL). Perform full-text regex searches across URLs, methods, operation names, request bodies, and response payloads.
  - One-Click Exports: Export API requests directly to Playwright, Cypress, or Postman formats for seamless integration into your automated testing and CI/CD pipelines.
  - JWT Decoding: Automatically detects Bearer tokens inside Authorization headers and decodes them inline, displaying the payload and expiration status directly in the UI.
  
  ###⚡ First-Class GraphQL Support
  Network++ is built from the ground up to understand GraphQL traffic:
  
  - Smart Auto-Detection: Identifies GraphQL requests via URL structures, content-type headers, and POST body patterns.
  - Batch Operation Handling: Automatically detects and displays batched GraphQL queries with operation count badges.
  - In-Depth Inspection: Clearly shows operation names, types (Query/Mutation/Subscription), variables, and syntax-highlighted query payloads.
  - Advanced Features: Detects APQ (Automatic Persisted Queries) and @defer/@stream incremental delivery responses.
  - Error Tracking: Dedicated GraphQL error count badges highlight failing queries instantly.
  - GraphQL Playground Integration: One click to open any query inside a public or custom GraphQL Playground for further exploration.
  
  ###🔒 Privacy-First & Secure
  Your data belongs to you. Network++ is designed for utmost security:
  
  - 100% Local Processing: All data interception, JSONPath evaluation, and collection storage happens entirely on your machine.
  - No External Servers: No telemetry, no analytics, and absolutely no tracking.
  - Minimal Permissions: Only requires standard DevTools and local storage permissions to function.
  - Offline Capable: Works perfectly offline or on internal company networks.
