Sessions are automatically grouped by domain for quick navigation. Advanced Filtering Toggle HTTP methods on/off to focus on specific request types. The search bar instantly filters across all sessions, helping you find that one request among hundreds. Beautiful JSON Viewer Switch between code view with syntax highlighting or tree view with collapsible nodes. Search within JSON responses with match highlighting and previous/next navigation. Request Comparison Select any two requests and compare their responses side-by-side. Visual diff highlighting shows exactly what changed between responses. Request Replay Click any request to open the replay editor. Modify the URL, headers, or body, then send it again. Perfect for testing API endpoints with different parameters. HAR Integration Export sessions to HAR 1.2 format for analysis in other tools. Import HAR files from tools like Chrome DevTools or Postman for analysis in ReloadScope's superior interface. Copy as cURL Instantly generate cURL commands from any request. Perfect for sharing with team members or running from the command line. Export to PDF Generate professional PDF reports of request details. Great for documentation, bug reports, or sharing with non-technical stakeholders. 🎯 Use Cases API Development Monitor API calls while developing frontend applications. Verify that requests are sent with correct parameters and responses match expectations. Debugging Reproduce bugs by comparing API responses between working and broken states. Use the diff tool to identify exactly what changed. Testing Replay requests with modified parameters to test API behavior. Export to HAR for integration with automated testing tools. Documentation Generate PDF exports of API requests for documentation purposes. Automatic schema generation helps document API response structures. Performance Analysis Track request timing and identify slow API calls. Export to HAR for detailed performance analysis. ⚙️ Technical Details Built With Modern Standards - Manifest V3 (latest Chrome extension standard) - Vanilla JavaScript (no framework dependencies) - Chrome Debugger API for network interception - Local storage only - no external servers Keyboard Shortcuts - Ctrl+Shift+C: Collapse all JSON nodes - Ctrl+Shift+E: Expand all JSON nodes - Search navigation with arrow keys - Smart Features Preserves session state when filtering - Remembers expanded/collapsed domains - Auto-scrolls to search matches - Intelligent JSON formatting 🎨 Interface Highlights Resizable Panels Drag the gutter to adjust sidebar and detail panel sizes to your preference.
