能不能出个手动模式啊，或者提供一个不需要嗅探的后缀列表，或者干脆不嗅探不在列表里的后缀。每次打开新标签都会提示两个TXT，强迫症分分钟发作啊。。。

挺好用的，如果视频大小窗口适应一下更好了！

Bob Peng (xifan)2016年4月30日

顺利抓到了视频，好用

chuang han2016年4月17日

十分有用的嗅探工具,希望加上复制全部链接到剪贴板功能

chun li2016年4月6日

好用，不知道为什么46.0版的抓得到，49.0版的抓不到

柳残阳2016年3月25日

最新版Google49.0.2623.87。嗅探失效

要是能能加视频抓取的略视图就更好了！因为每次在Facebook上抓取到的视频，如果想要下载那个视频的话还要慢慢数！还会数错！希望增加视频略视图能让人知道下载的上那个视频！

Enables users to detect and download media resources (videos, audio, streams) embedded in or streamed from web pages, which are otherwise difficult to extract or save locally

User browses a webpage → extension monitors network requests via webRequest API → detected media resources (video, audio, streams) are listed in popup → user can preview, filter, select, and download the media → supports advanced features like M3U8 parsing, stream recording, and integration with external download tools

Target users: Users who need to download streaming video/audio from websites / Content creators archiving web media / Users who want to extract media from web pages for offline viewing / Technical users who need M3U8/DASH stream parsing tools

No login or paid features detected - this is a straightforward open-source tool with full functionality available freely
All keyword hits for 'auth', 'session', 'token' were confirmed as false positives related to Chrome APIs and HTTP header capture, not user authentication
The extension is well-documented on GitHub and Gitbook with 700K+ users and high rating (4.68), indicating mature, community-supported tool

Monetization

No paid features detected

Extension is explicitly open source. No premium tier, subscription, purchase, or payment UI detected. The 'pro' keyword matches are all false positives from localization files where 'pro' appears in words like 'protocol', 'progress', 'protection', 'prompt'. No payment platforms (Stripe, PayPal, etc.) or billing APIs found. All features appear freely accessible without any gating.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: No login UI, authentication flow, or user account system found. The 'session' keyword matches are all from chrome.storage.session API (Chrome's built-in session storage, not user authentication). The 'auth' keyword matches are HTTP Authorization header capturing (for media sniffing) and a legal disclaimer about 'authorized access' to content. The 'token' keyword is for aria2 RPC integration with a local download manager. No OAuth, sign-in, or account registration flows exist.
