HAR Inspector: Local Network Waterfall & Masked Reports
Inspect a local HAR file, filter network entries and read a timing waterfall with masked values, without replaying requests or executing responses.
Enabling local controls…
1. Open a local HAR
Parsed only in a browser Worker. No upload, storage or request replay. Accepts HAR 1.2 log.entries; not a complete HAR schema validator. URL, method and status are required; other missing fields are omitted or unknown. UTF-8: 10 MiB; 10,000 entries; 500,000 JSON nodes. URLs, headers, cookies, queries, bodies and arbitrary values are masked by default; reports always stay redacted.
2. Waterfall and redacted report
Choose a file, paste JSON or load a sample, then inspect.
How to use this tool
Load a supported HAR or example, inspect the request summary and waterfall, filter entries and download a masked report. Unknown timing remains unknown.
When not to use it
HAR files can expose credentials, URLs and bodies even when familiar headers were removed. This is not a packet capture, remote performance audit or safe raw-HAR sharing service.
