#### 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.
