HAR File Analyzer
Break down a browser HAR network capture.
| Status | Method | URL | Size | Time | Waterfall |
|---|
This free HAR file analyzer breaks down a HTTP Archive (.har) capture from your browser's Network tab. It summarizes the total requests, transfer size, wall-clock load time and cache hits, groups traffic by content type and by domain, and draws a timing waterfall showing how each request's time splits across DNS, connect, TLS, request, wait (TTFB) and download phases — so you can spot slow servers, render-blocking resources and third-party bloat. Filter by type, search by URL or status, and click any row to expand its full timing breakdown. To create a HAR: open DevTools → Network, reload the page, then right-click and "Save all as HAR".
