Professional Network Request Debugger for Chrome
The only Chrome extension that keeps your API history when you refresh.
Debug smarter, not harder.
Three powerful reasons that set us apart from everything else
DevTools loses everything on refresh. We don't.
Postman requires manual setup. We auto-capture.
Other extensions lack features. We're complete.
Everything you need for professional API debugging
Keep all API history across page refreshes and browser restarts. Configure history limits from 100 to 2000 requests.
One-click replay with full editing. Change method, URL, headers, params, and body. Like Postman built into your browser.
DataDog-style time windows: Live, 5min, 10min, 20min, 30min. Focus on recent activity or isolate specific time periods.
Real-time metrics: success rate, error rate, average response time, fastest/slowest requests, breakdowns by method and status.
Export as JSON, HAR, or CSV. Share with team or import to other tools. Only exports currently filtered data for precision.
Group by domain, method, or status. Collapsible groups with counts. Perfect for organizing high-volume APIs and microservices.
Open in separate window, stays on top (optional). Perfect for dual-monitor setups. Monitor APIs while coding.
Filter to show only current tab's requests. Works in floating windows. Perfect for multi-tab debugging sessions.
Combine search, domain, method, status, errors-only, time range, and tab filters. Find exactly what you need instantly.
Auto-hide tracking, analytics, and ads. Pre-loaded with common domains. One-click block from any request. Custom management.
VS Code-inspired dark/light themes. Clean, modern, responsive design. Full-width layout with clear visual hierarchy.
Comprehensive help system. Feature explanations with "What it does", "How to use", and "Why it's useful" for every feature.
