HttpCanary

HttpCanary HttpCanary is an Android HTTP, HTTPS, and HTTP2 packet analyzer that helps developers test REST APIs without root. Capture traffic, inspect protocols like WebSocket and TLS/SSL, and inject requests or responses in static or dynamic modes.

HttpCanary

HttpCanary is an Android app built to capture and inspect network traffic for HTTP, HTTPS, and HTTP/2. It’s designed for developers and testers who want to verify and troubleshoot mobile REST APIs—without needing root access. With this tool, you can monitor requests/responses and adjust them when necessary to better understand what’s happening on the network.

The app supports a broad set of protocols and secure connections, including HTTP/1.0, HTTP/1.1, HTTP/2.0, WebSocket, and TLS/SSL. That flexibility makes it useful for many kinds of networking and debugging tasks.

A standout capability is request/response injection. You can modify traffic using two injection styles: static and dynamic. In static mode, multiple injectors can run at the same time, letting you change things like query parameters, headers, bodies, and even status lines based on your testing needs. This helps you confirm your APIs behave correctly and speeds up debugging.

Key Features

Packet Capture

Use HttpCanary to view the network data you care about so you can analyze it. It’s built for inspecting traffic across multiple protocols, ranging from TCP and UDP to HTTP/1.0 and beyond.

You can examine captured content in multiple formats, including headers, hex, text, raw, cookies, URL, and even media-related data such as audio and images. You can also review session-style summaries like the HTTP method, protocol version, response code, content type, and more.

Protocol and Device Support

HttpCanary handles many protocols, including WebSocket, TCP, TLS/SSL, UDP, HTTP/1.0, HTTP/1.1, and HTTP/2.0.

Compatibility depends on your Android version, but the app is intended to work across a wide range of devices. Once installed, you can use it to capture and analyze traffic from your everyday setup.

Browser and Content Overview

With HttpCanary, you can inspect network activity from browsers and apps installed on your phone. The app provides detailed views such as:

• Headers
• Hex
• Text
• Raw
• URL



• JSON
• Cookies
• Images
• Audio

This removes the need to rely on separate tools for basic visibility—everything is presented inside the app so you can explore captured sessions quickly.

Additional Functions

Data Packet Analysis

The app includes a powerful data packet analysis system that helps you understand the full path of data flow. This can reveal details about transfers that might otherwise be easy to miss.

Website Control

If you want to limit access, HttpCanary provides a blocking capability. You can manage unnecessary website access and experiment with changes while using your mobile device.
