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.
