HARScope — Offline HAR Viewer

About

Someone asked you to "send a HAR" — or you exported one from DevTools — and now you need to actually read it. HARScope opens HAR files right in your browser and lays them out clearly.

Drag in a .har file (or click Open) and you get:
• A request waterfall and a fast, searchable request table
• Status, method, type, size and time for every request
• A detail panel with request/response headers, query string, request payload, response body, and timings
• Filters by URL, type, method and status

★ WHY HARSCOPE — IT'S OFFLINE
HAR files quietly contain cookies, auth tokens and request bodies. Most "HAR viewers" are websites that make you UPLOAD that sensitive file to their server. HARScope doesn't. It has ZERO permissions, makes no network requests, and reads your file entirely on your device. You can hand it a HAR full of secrets without a second thought.

★ HANDLES BIG FILES
A virtualized table keeps things fast even on HARs with thousands of requests.

★ HOW TO USE
1. Click the HARScope icon to open the viewer.
2. Drag your .har file onto it (or click "Open HAR file…").
3. Click any request to inspect it. Filter and search as needed.

No account, no ads, no tracking. Just a clean, private HAR viewer.
