# HAR file viewer

Open a HAR log locally to see totals, breakdowns by type and host, the twenty slowest and largest requests, and failures, then download a redacted copy safe to share.

Everything here runs on this device. Nothing is uploaded. Sizes recorded as -1 count as zero, and response bodies only exist in a HAR when the browser captured them, so their redaction count is often zero. This is a summary, not a debugger: there is no waterfall timeline, no request replay, and entries past the ceiling are counted but not analyzed.
