burstHAR

Monitor page API requests, save matches, edit and replay them, then export captures and responses as HAR.

burstHAR helps developers capture the exact page API requests they care about, inspect the saved request/response data, edit a request, replay it, and export the result as a HAR file. Use the toolbar popup to turn monitoring on, add match rules for a host, full URL, request payload, response payload, or phrase, then open the burstHAR captures workspace to review everything in one place. Keep only the specific network requests that you'd like for HAR exporting, so that you have a clean file to show or compare from. Key features: Capture matching HTTP, fetch() and XMLHttpRequest traffic from pages you choose. Match by URL, request data, response data, or request + response content. Save request headers, bodies, response metadata, and optional response bodies. Filter captures by URL, method, status, headers, body text, or raw HAR content. Edit method, URL, headers, body, credentials mode, redirect mode, and timeout before replaying. Export one capture or the full capture set as a HAR file. Works without attaching Chrome's debugger, so there is no debugger banner. Privacy note: captured request and response data is stored locally in your browser profile only. burstHAR is intended for debugging your own websites, applications, and accounts. Do not capture or share sensitive data unless you are authorised to do so.
