HTTP Archive (.har) waterfall timeline, payload inspector, and audit tool
HAR Waterfall Viewer is a fast desktop HTTP Archive (.har) analyzer, multi-phase waterfall timeline visualizer, and web performance audit tool for Linux. Built for web developers and engineers who want to inspect captured network sessions locally without browser overhead.
Key Features:
- HTTP Archive Waterfall Timeline: Parses W3C .har JSON files and renders multi-phase waterfall timing bars (Blocked, DNS, Connect, TLS, TTFB Wait, Receive) with HTTP status badges, MIME type filters (Document, JS, CSS, Img, XHR/Fetch, Font), transfer sizes, and duration search.
- Request & Response Inspector: Detailed tabbed viewer for Request and Response Headers, parsed Query Parameters, Form and JSON payloads, Cookies, and a per-phase timing breakdown.
- Performance Bottleneck Audit & Exporter: Aggregates transfer bytes by MIME type, automatically flags slowest and largest assets (>1s or >500KB), and exports structured CSV and self-contained HTML performance reports.
Disclaimer: HAR Waterfall Viewer is an independent open-source project by TC Studio and is not affiliated with, endorsed by, or sponsored by any third-party web debugging vendor.
