Effortlessly capture TLS encrypted traffic in a cross-platform GUI using eBPF, without configuring CA certificates or performing Man-in-the-Middle (MITM) attacks.

eCaptureQ is a cross-platform GUI for eCapture, visualizing its eBPF-powered packet capturing capabilities: capture TLS plaintext at the kernel level without needing a CA certificate or MITM.

This means you can debug and analyze the encrypted communications of any program in a simpler, more efficient, and non-intrusive way.

Certificate-Free Capture with eBPF: Directly capture and decrypt TLS traffic from the kernel without configuring CA certificates or a man-in-the-middle proxy.

Real-time & Responsive View: Displays network requests in real-time and automatically switches between a desktop table view and a mobile card view based on the device.

Cross-Platform & Dual-Mode: Runs as an all-in-one tool on Linux/Android, and as a remote client on Windows/macOS/Linux to connect to a server.

Secure, Lightweight, and Native Experience: Built with Rust on the backend for memory safety and native performance.

eCaptureQ offers two main operating modes to suit different user needs.

This is the standard, all-in-one mode. In this mode, the ecapture binary is bundled directly within the eCaptureQ application.

• Supported Platforms: Linux, Android

• Features:
  • Out-of-the-Box: No need to manually install or configure ecapture.
  • Automated Management: eCaptureQ automatically manages the lifecycle of the capture process.
  • Simple and Convenient: Ideal for quick traffic analysis on a local device.
• Requirements:
  • On Linux and Android, this mode requires root privileges to run the eBPF program.

In this mode, eCaptureQ runs as a standalone client without the bundled ecapture binary. It connects remotely via WebSocket to an ecapture instance that is manually run by the user.

• Client-Supported Platforms: Linux, Windows, macOS
• Features:
  • High Flexibility: Run ecapture on a Linux server and monitor it remotely from a Windows or macOS machine.
  • No Root Required: The eCaptureQ client itself does not require root privileges.
  • Secure Isolation: Suitable for scenarios where the capture process and the analysis interface need to have separate permissions.
• Requirements:
  • The user must download and run ecapture separately on the target device.
  • ecapture must be started with the --ecaptureq flag to activate the WebSocket service.

1. Download and install the standard version of eCaptureQ.
2. (Linux only) Run the application with sudo:

   sudo /path/to/ecaptureq

3. Click "Start" in the application interface to begin capturing.

1. On the target Linux machine, download and start ecapture with the --ecaptureq flag. Ensure the WebSocket address is accessible from your eCaptureQ client.

   # Run on the target server (requires root privileges)
   sudo ./ecapture tls --ecaptureq ws://0.0.0.0:28257

2. On your Windows/macOS/Linux machine, download and run the decoupled version of eCaptureQ.
3. Go to the settings page in eCaptureQ.
4. Configure the "WebSocket Server URL" to the address ecapture is listening on (e.g., ws://<SERVER_IP>:28257).
5. Return to the main page and click "Start" to begin receiving data.

• Core Engine: ecapture (The underlying eBPF capture tool)
• Framework: Tauri (A framework for building cross-platform applications with Rust)
• Backend: Rust (with Tokio for asynchronous processing and Polars for high-performance data handling)
• Frontend: React with TypeScript, Tailwind CSS

• ecapture: Capturing SSL/TLS plaintext without a CA certificate using eBPF.
• Tauri: Build smaller, faster, and more secure desktop and mobile applications with a web frontend.
