ApiCatcher is a user-friendly mobile HTTP/HTTPS/WS/WSS packet capture and debugging tool.
[Key Features]
- Traffic Capture: Capture HTTP, HTTPS, WS, and WSS traffic (WS: WebSocket; WSS: WebSocket over TLS).
- Data Manipulation: Copy, export, encrypt, and decrypt Query Params, Headers, and Bodies.
- Host Filtering: Configure blacklists and whitelists to filter captured hosts.
- Request Replay: Modify and resend requests (WS/WSS replay serves as a debugging tool).
- Chain Replay: Schedule and execute multiple requests sequentially based on dependencies, with support for dynamic parameter injection (HTTP/HTTPS only).
- Scheduled Replay: Automate and trigger request replays at set intervals (HTTP/HTTPS only).
- Auto-Generated API Docs: Automatically generate API documentation and export directly to Postman or Apifox (HTTP/HTTPS only).
- Rewrite Rules: Mock responses, redirect requests, modify requests/responses, or drop requests/responses (HTTP/HTTPS only).
- Scripting Engine: Extend capabilities with script plugins to flexibly modify requests and responses on the fly (HTTP/HTTPS only).
- History Export: Batch export captured traffic as HAR files (HTTP/HTTPS only).
- API Scanner: Run rule-based vulnerability/error detection and statistics on captured traffic, with support for custom scanning rules (HTTP/HTTPS only).
- Media Export: Batch export images and videos, with automatic merging for segmented download requests.
- Real-Time Sync: Stream captured HTTP/HTTPS traffic instantly to ApiCatcher Desktop for advanced analysis and debugging.
[How It Works]
ApiCatcher establishes a local VPN connection on your device to route all network traffic through a local Man-in-the-Middle (MITM) service. As long as the VPN is active, ApiCatcher can capture any HTTP/HTTPS/WS/WSS traffic passing through Wi-Fi or cellular data.
[Data Privacy & Security]
ApiCatcher's root certificate is a self-signed certificate generated entirely on your own device. All captured HTTP/HTTPS/WS/WSS data is stored locally on your device and is never uploaded to any remote servers.
The Ultimate Mobile Packet Capture Tool – A Must-Have for Debugging!

ApiCatcher is absolutely amazing! It completely solves the pain points of mobile packet capture. The interface is clean, the operation is simple, yet the features are incredibly powerful – request replay, Mock responses, and especially encryption/decryption capabilities, everything you need is all in one place.
Wonderful App!

Just what I was looking for: an easy-to-use HTTPS traffic capture app with good filtering options and a powerful JSON viewer. Plus, the more advanced features are amazing: the auto-generated API documentation is very helpful. The developer is very responsive and no subscription!
