HTTP Request Recorder

About

HTTP Request Recorder captures every fetch and XMLHttpRequest your browser tabs make, organises them by domain and date, and lets you inspect request and response details in a calm dark UI.

KEY FEATURES

• Per-tab recording — click the toolbar icon to start or stop. A REC badge shows on the icon while a tab is being recorded.

• Live previews — requests appear in the history page the moment they go out. Streaming responses (Server-Sent Events) update in real time.

• Three-column history — browse by date, by domain, and by request. Pick a row to see method, status, URL, timing, headers and body in the right panel.

• JSON viewer — handles huge response bodies without freezing the UI.

• Side-by-side compare — pick two requests to the same endpoint and see a row-aligned diff of URL parameters, headers and bodies. Loose mode lets you compare across environments (sandbox vs production) and across path prefixes.

• Token masking — Authorization, Cookie, X-Api-Key and other sensitive headers are masked by default with a per-row reveal toggle.

• Optional Cookie / Set-Cookie capture — browser security normally hides those headers from in-page JavaScript. Tick "Capture extra info" in the popup to additionally record them via chrome.webRequest. Off by default.

• Local-only storage — everything lives in your browser's IndexedDB. No analytics, no telemetry, no remote servers. The extension makes no network calls of its own.

• Domain block list — silence noisy domains from the history without losing other captures.

• Export — save a domain's worth of captures as JSON files inside a single ZIP archive.
