FAQ
How do I read a HAR file for free?
Paste the file contents and this page lists each request with its method, status, response size and time, plus totals and a breakdown by status class — on your device with no upload.
Is it safe to analyse a HAR that contains cookies or tokens?
Yes, and it is the main reason this tool is client-side. HAR exports routinely include auth headers, cookies and internal URLs; here they are parsed in your browser and nothing is transmitted or stored, which you can verify by turning off your Wi-Fi.
What does the status breakdown show?
Requests are grouped by class — 2xx, 3xx, 4xx, 5xx — so you can spot failures and redirects at a glance.
Can it handle a large capture?
It handles typical captures comfortably and shows the first hundred requests in the table, with the totals computed across all of them.
Limits
Summarises requests, sizes and timings; it does not replay requests or decode response bodies.
