About HAR Debugger

中文产品介绍 无需打开 DevTools,一键录制当前标签页网络请求,并导出标准 HAR 文件。 HAR Debugger 是面向开发者、测试工程师和技术支持人员的网络请求录制工具。用户无需打开 Chrome DevTools,只需在扩展弹窗中点击“开始录制”,复现页面问题后点击“停止并导出”,即 可生成标准 .har 文件。 新版优化了录制流程和使用体验:支持弹窗状态展示、首次安装使用说明、多语言界面、后台 生成 HAR、响应体等待机制以及大文件导出优化。导出的 HAR 可导入 Chrome DevTools Network 面板,也可用于支持 HAR 的网络分析工具。 适用场景: - 页面接口问题排查 - 前后端联调请求留存 - 测试复现网络问题 - 客服/技术支持收集用户侧网络证据 - 无需用户打开 DevTools 的轻量抓包流程 HAR Debugger 仅在用户主动点击“开始录制”后捕获当前标签页的网络事件,并在用户点 击“停止并导出”后在本地生成 HAR 文件。扩展不会将 HAR 数据、请求内容、Cookie、Token 或任何浏览数据上传到远程服务器。所有数据处理均在用户本地浏览器中完成。 注意:HAR 文件可能包含 URL、Header、Cookie、Token 和响应内容,请谨慎分享。 English Product Description Short description: Record network requests from the current tab and export a standard HAR file without opening DevTools. Long description: HAR Debugger is a lightweight network recording extension for developers, QA engineers, and support teams. Instead of opening Chrome DevTools, users can start recording from the extension popup, reproduce a network issue, then stop and export a standard .har file. This major update improves both reliability and usability: popup-based controls, live recording status, onboarding guide, multilingual UI, background HAR generation, graceful response body collection, and optimized large-file export. Exported HAR files can be imported into Chrome DevTools Network panel and other HAR-compatible analysis tools. Common use cases: - Debug frontend API issues - Capture network evidence for bug reports - Support QA and customer troubleshooting - Record requests without asking users to open DevTools - Export shareable HAR files for HTTP/HTTPS analysis HAR Debugger only captures network events from the current tab after the user > explicitly clicks “Start recording”, and generates a HAR file locally after the > user clicks “Stop and export”. The extension does not upload HAR data, request > content, cookies, tokens, or browsing data to any remote server. All processing > happens locally in the user’s browser. Note: HAR files may contain URLs, headers, cookies, tokens, and response bodies. Share them carefully.
