HTTP/HTTPS/WS MITM Proxy
Only for Mac
Free · In‑App Purchases
Mac
TxChops is a network debugging proxy for developers and QA engineers. Capture, inspect, and modify HTTP, HTTPS, and WebSocket traffic on your Mac or iPhone.
Built for anyone who needs to:
• Debug API calls between apps and servers
• Inspect HTTPS requests and responses with SSL/TLS decryption
• Test app behavior by changing requests and responses
• Simulate slow or unreliable connections
• Customize and automate traffic modifications with JavaScript
KEY FEATURES:
▸ Sessions — Explore requests, responses, and WebSocket messages. Search and filter captured sessions, then export to HAR.
▸ System Traffic Capture — Capture traffic from apps on your device in one place.
▸ HTTPS Decryption — See inside encrypted requests and responses with a certificate you install and trust.
▸ Breakpoints — Pause requests and responses, edit headers or bodies, then continue or drop them.
▸ Map Rules — Redirect requests, serve local files, or rewrite URLs to test without changing your app.
▸ Scripts — Shape traffic your way with custom JavaScript. Modify requests, transform responses, and automate your workflow.
▸ Throttle — Simulate slow connections with adjustable bandwidth, latency, and packet loss.
▸ External Proxy — Route requests through an HTTP or SOCKS5 proxy, with rules for individual hosts.
Captured sessions stay on your device unless you choose to export or share them. TxChops processes traffic locally and does not upload captured data to our servers.
Start free. Try HTTPS decryption for 30 days, then unlock it with a one-time purchase. No subscription. Other features remain available without a purchase.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Added script annotations in session details, so scripts can display analysis results alongside the overview, request, and response. Fixed response scripts changing fields that were not explicitly supplied.
- Improved WebSocket browsing with compressed-message decoding, readable text and binary previews, and expandable frame details. Fixed unexpected disconnects and incorrect session completion.
- Added Requests, a dedicated API workspace replacing Edit and Replay. Create requests or open captured sessions to edit, resend, and compare responses.
- Save requests in collapsible collections, work in multiple tabs with automatically saved drafts, and revisit request history.
- Edit query parameters, headers, and request bodies, with support for text, JSON, forms, and file uploads.
- Send directly without starting capture, or route through TxChops to use proxy rules. Inspect response status, timing, headers, and body previews; save responses to files or copy requests as cURL commands.
- Added a mobile certificate setup guide with a QR code for iPhone, iPad, and Android. The certificate download page works through both HTTP and SOCKS5 proxies.
- Added support for additional trusted server certificates, making it easier to inspect HTTPS traffic in development environments.
- Improved large-response handling and added lightweight body and image previews to reduce memory use. Capture limits no longer interrupt traffic, and incomplete captures are clearly identified.
- HAR exports hide sensitive information by default, with options to customize what is hidden.
- Fixed enabling system traffic capture while the proxy is already running. System capture now stops automatically when TxChops quits or crashes.
- UI Improvements.
