Packet Capture Pro
Powerful, cross-platform network debugging made simple

Packet Capture Pro is a lightweight, developer-friendly tool for capturing and analyzing HTTP/HTTPS/WebSocket traffic. Built for modern development and QA workflows, it helps you quickly identify and resolve network issues across devices and platforms. With multi-device support and seamless access through a single account, it’s perfect for teams needing a unified, reliable, and efficient debugging experience.


Key Features：

● Packet Capture

Capture HTTP/HTTPS/WebSocket traffic using a local VPN. View detailed request and response data in real time, including headers, status codes, and payloads. Easily switch between raw text, JSON, XML, HTML, images, and videos for efficient debugging.

● Cross-Device Collaboration

Stream mobile traffic to your PC for real-time analysis on a larger screen. Connect via QR code or IP/port for seamless teamwork across devices. Visit our website to download Packet Capture Pro for Windows and iOS.

● Rewrite & Replay

Rewrite is one of PCP’s core debugging features. It allows automatic modification of network requests and responses based on preset rules. Five modes are supported: request replacement, response replacement, request modification, response modification, and redirection. Multiple rewrite rules can run simultaneously, making it easy to simulate and debug complex network behaviors efficiently.
Replay enables you to re-execute captured requests to reproduce issues. Advanced Replay allows you to customize replay counts, delays, and intervals, making stress testing and validation more efficient.

● Import & Export

Export locally captured data for sharing or future review.
Import external capture files for analysis directly within the app.

● Custom Capture Rules

Bypass: Exclude traffic from specific domains so it won't be captured.
Intercept: Target and capture traffic from selected domains for deeper analysis.

● Smart Filtering

Quickly locate issues with keyword search and URL filtering. Narrow results by content type such as JSON, HTML, XML, images, or videos.

● Tools

Packet Capture Pro’s Tools module offers everything you need to streamline packet analysis and troubleshooting. It supports text encryption/decryption and multiple encoding/decoding formats including URL, Base64, Unicode, and MD5. You’ll also find practical utilities such as timestamp conversion, certificate hash conversion, regex testing, and QR code generation/ scanning.
All tools are built to match the actual needs of packet capture and network debugging—making your workflow faster, smoother, and far more efficient.

● Privacy First

All captured traffic is processed locally. A self-signed certificate is generated on your device, ensuring your data never leaves your control.
