Stream HTTP Sniffer vs Packet Capture Pro

Stream HTTP Packet Capture Tool is a mobile HTTP/HTTPS packet capture and network debugging tool. It is used for local packet capture on the client side, intended solely for local network debugging by QA and development teams. You can capture and view all HTTP/HTTPS requests and responses on your device without connecting to a computer, making it easy to debug application network issues. 1. Capture HTTP & HTTPS requests, with HTTPS requests requiring the configuration of a CA certificate. 2. Access capture history to preview request bodies and response bodies, currently supporting text, JSON, files, and forms. 3. Domain Filtering: Intercept only the traffic you need, avoiding interference with other applications. 4. Request Rewriting: Supports redirection and replacement of request or response messages, and modifications based on regular expressions. 5. Request Blocking: Block requests based on URLs to prevent them from being sent to the server. 6. Scripting: Write JavaScript scripts to handle requests or responses. 7. Search: Search requests based on keywords, response types, and various conditions. Before you start using the tool, please read the following: 1. The target audience for Stream HTTP Packet Capture Tool includes front-end developers, client developers, back-end developers, DevOps engineers, QA engineers, and general users with some network analysis skills. 2. The sole purpose of Stream HTTP Packet Capture Tool is network debugging, and it has no other intended purposes. Additionally, enabling Stream requires your authorization for VPN permissions. 3. Stream HTTP Packet Capture Tool does not upload any user data. Please use it with confidence, and we hope our trusted users will share it with industry professionals. If you do not agree with the above purposes, lack network analysis skills, or inherently distrust third-party apps with sensitive data, we recommend you carefully consider before downloading.
