SnapHAR

About

That prompt is the guidance for the Description field — it wants "what it does + why install." Here's a version tuned exactly for that (leads with what it does, then a clear "why install"), still honest and non-salesy:

SnapHAR captures a browser tab's network activity and saves it as a standard HAR 1.2 file — without opening DevTools.

Getting a HAR today is a fiddly dance: open DevTools, find the Network tab, turn on Preserve log, reproduce the problem, right-click, export. SnapHAR replaces all of that with two clicks. Open the popup, click Start Recording, reproduce the issue, then Stop & Export. A valid .har lands in your Downloads — ready to re-import into the DevTools Network tab, attach to a bug report, or send to support.

Why install it:
• Faster — one click instead of the manual DevTools flow.
• Reliable — recording keeps running across reloads and redirects, so you never lose the request you were chasing.
• Complete — response bodies, full timings, headers, cookies, and pages, as spec-compliant HAR 1.2.
• Safe to share — sensitive headers, cookies, and URL tokens are redacted by default (further than DevTools), and you control exactly what's captured.
• Private — no servers, no analytics, no telemetry. Everything is built locally and saved to your device; the debugger permission is used only while you record.

Keep the Summary as the short one-liner from before:
One-click HAR capture. Record a tab's network traffic and export a HAR 1.2 file — no DevTools required.
