Flight Recorder is a Chrome add-on designed to assist developers in managing network requests during the debugging process. This free tool allows users to maintain a local, filtered history of recent network requests for the current tab, even if the Chrome DevTools are closed. It is particularly useful in scenarios where network events such as redirects, retries, or authentication failures occur before the developer has a chance to open the DevTools.

Key features of Flight Recorder include the ability to record recent network activity specific to the active tab, maintaining data local to the current browser session, and filtering requests based on various criteria like search terms, method, status, type, and errors. Users can inspect request and response headers, capture request payload summaries, export sessions as JSON or HAR files, and copy sanitized cURL commands for selected requests, making it a valuable tool for focused debugging.
