REQUEST TIME-LAPSE DevTools panel that records, groups, and replays network request history for API regression debugging. Request Time-Lapse is a powerful Chrome DevTools extension designed for developers and QA engineers who need to analyze and debug network request patterns and API changes. Record and analyze network requests in real-time directly from Chrome DevTools. Compare snapshots, filter by status codes, latency, or response content, and export data in multiple formats for team collaboration. RECORD AND MONITOR Automatically records all HTTP/HTTPS network requests. Groups requests by endpoint and method. Real-time display with request/response details. Storage quota monitoring with warnings. POWERFUL FILTERING Filter by HTTP status codes (200, 404, 500, etc.). Filter by response latency in milliseconds. Search response content by keywords. Combine multiple filters for precise analysis. COMPARE MODE Side-by-side comparison of request snapshots. Detailed diff highlighting changes. Identify regressions before deployment. Verify API changes are working as expected. MULTI-FORMAT EXPORT JSON Export for full data and programmatic analysis. CSV Export to open in Excel, Sheets, or Tableau. HTML Export to share beautiful reports with non-technical stakeholders. DARK AND LIGHT THEMES Professional dark theme by default. Light theme for bright environments. Automatic preference saving. POWER USER SHORTCUTS Ctrl+K to focus search. Ctrl+E to open export menu. Ctrl+T to toggle theme. Ctrl+Shift+C to enable compare mode. Arrow keys to navigate requests. USE CASES API Regression Testing - Monitor API responses before and after deployments to catch breaking changes immediately. Performance Analysis - Identify slow endpoints and latency issues during development and testing. Integration Debugging - Track request and response data for third-party integrations and external APIs. Team Collaboration - Export reports in HTML format to share findings with team members and stakeholders. Quality Assurance - Create snapshots at different stages of testing and compare them to verify behavior. GETTING STARTED Open Chrome DevTools by pressing F12. Navigate to the Request Time-Lapse tab. Perform your workflow and requests will record automatically. Use filters to find specific requests. Compare snapshots or export data. Click the extension icon anytime for tutorial and help. Documentation available at https://github.com/jomardyan/Request-Time-Lapse Quick Start Guide takes 2 minutes. Keyboard Shortcuts help speed up workflow. Filtering Guide helps find exactly what you need. Export Guide shows how to share data in the format you need. Troubleshooting provides solutions to common issues. PRO TIPS Take snapshots before major changes. Compare snapshots before and after deployments. Create a history of API behavior by exporting weekly. Filter before analyzing to focus on relevant data. Learn keyboard shortcuts to significantly speed up workflows. REQUIREMENTS Chrome 90 or higher. DevTools access. Read permissions for network requests which is a standard DevTools capability. PRIVACY AND SECURITY All data is stored locally in your browser. No data sent to external servers. No tracking or analytics. You maintain full control of your data.
