Trace Recorder

Records a DevTools performance trace + full HAR (with bodies) of the active tab. Toggle via the toolbar icon, save as ZIP.

Trace Recorder — capture performance & network in one click Trace Recorder records a complete DevTools performance trace and a detailed HAR file of the active tab in a single click, then bundles them into a ZIP archive ready to share or analyze. What it does - Start/stop recording with one click on the toolbar icon (a "REC" badge shows a capture is in progress). - Captures a full DevTools performance trace (timeline, rendering, JavaScript, GPU, network…) via the Chrome debugging protocol. - Records all network traffic as HAR, including response bodies, as well as WebSocket exchanges. - Exports everything as a timestamped ZIP (trace + HAR + session metadata). Benefits for users - Saves time: no need to open DevTools, start a profile and export manually — everything is captured and packaged automatically. - Complete diagnostics: performance trace and network traffic in a single deliverable, ideal for reproducing and analyzing an issue. - Easy sharing: one ZIP file to send to a developer, attach to a support ticket, or archive. - Robust: the capture is recovered even if the browser suspends the extension mid-recording. - No data sent anywhere: everything stays local, and the archive is saved straight to your machine.
