About

Proxygen

This tool allows developers to intercept, inspect, and modify HTTP traffic from their iOS devices on a Mac. It offers advanced features like JavaScript scripting for traffic manipulation and a syntax-aware editor for debugging API endpoints.

Highlights
  • Send iOS device traffic to Mac
  • Modify proxied traffic with JavaScript
  • Match and replace headers/body data
  • Syntax highlighting HTTP editor
  • WebSocket and SSE message capture
  • Local VPN extension for proxying

Proxygen is the best HTTP proxy tool for testing apps and debugging remote API endpoints right on your iPhone, iPad and Mac. And it’s built to delight you while doing it. Features • Send iOS device traffic to remote Mac • Write JavaScript to modify proxied traffic • Store state in variables for use in Editor • Match and replace headers and body data • Test API endpoints with assertions • Transform data with custom recipes • Syntax highlighting HTTP message editor • Message history with powerful filtering • WebSocket and SSE message capture • Store all data in documents SEND TO MAC Easily capture HTTP messages from an iPhone or iPad on your Mac. Traffic is mirrored to the paired Mac over local network even when the iOS app is not active. The Mac app can intercept and edit data of requests and responses before they are forwarded. No more futzing around with Wi-Fi proxy settings and trusted certificates. SCRIPTING Write JavaScript code that modifies proxied traffic. Scripts have access to requests and responses, letting you rewrite headers, URLs and body content, inject data, or implement conditional logic that goes beyond what static rules can express. SYNTAX AWARE EDITOR Edit requests from the message history or create new to any target. All previously sent requests are kept in the project file so you can return to your work later. The editor uses Tree-sitter for fast language parsing and syntax highlighting. It handles decoding of HTTP content automatically, letting you focus on testing the remote API. SERVER GRADE PERFORMANCE The magic lies in a little custom HTTP proxy that the iOS app runs in a local VPN extension. This proxy was developed using SwiftNIO, a framework for bizarrely fast asynchronous network applications. The proxy can perform TLS Manipulator in the Middle (MitM) to see inside HTTPS connections and apply custom logic to each message. To put it bluntly, you’ve probably never seen a HTTP proxy this fast before. And you likely won’t notice that your web browsing is even proxied at all. PRIVACY Proxygen contains no third party frameworks for crash reporting or analytics. Note that Proxygen is a TLS MitM proxy, which means that it sees HTTPS network traffic in plain text. This data is transferred from the proxy to the Proxygen app and stored as part of the project document. Make sure you handle the documents accordingly, as they may contain sensitive data such as session tokens and login credentials.

About

Stream HTTP Sniffer

This tool captures and analyzes HTTP/HTTPS traffic directly on your device for network debugging. It allows developers and QA teams to inspect requests and responses, filter traffic, rewrite messages, and even block specific requests. HTTPS capture requires CA certificate configuration.

Highlights
  • HTTP/HTTPS packet capture
  • Request/response history
  • Domain filtering
  • Request rewriting
  • Request blocking
  • JavaScript scripting
  • Keyword search

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.

Verdict

The call

The clearest difference is review sentiment: Proxygen at 83% against Stream HTTP Sniffer's 11%. Proxygen also leads on rating (4.3 vs 3.0) and chart position (#109 vs unranked). Stream HTTP Sniffer's advantage is update cadence (every 5 days vs every 2 weeks) and iOS requirement (13.0 vs 16.4). On price, ads, in-app purchases and monetization model there is nothing between them.
