Analizador de archivos HAR PROCESAMIENTO LOCAL

Analiza un archivo HAR exportado por el navegador para identificar solicitudes lentas, errores HTTP, tamaño transferido y tiempos por host. El archivo se procesa localmente y nunca se reproduce una solicitud.

HAR files can contain URLs, headers, cookies, and response metadata. The file is read and analyzed only in your browser.
HAR JSON input

Supports standard HAR files with log.entries. The tool summarizes the capture and does not replay any request.

The analyzer does not make any network request. Timing values reflect the HAR export, so use it as a review aid alongside browser performance and backend observability data.
