# MinPin

> MinPin is a native macOS HTTP/HTTPS debugging proxy for developers. It captures, decrypts
> (per host, opt-in) and modifies HTTP/1.1, HTTP/2, WebSocket, gRPC, GraphQL and SSE traffic
> from Mac apps, browsers, the iOS Simulator and iPhone/Android devices, and includes a local
> MCP server so AI coding assistants (Claude Code, Cursor, VS Code, Windsurf, Claude Desktop)
> can read captured traffic.

- Platform: macOS 12 or later, Apple Silicon and Intel (universal), notarized by Apple.
- Distribution: direct download only (not on the Mac App Store). https://download.minpinproxy.com/MinPin.dmg
- Pricing: Free tier (full capture and SSL decryption in 30-minute sessions); PRO Personal $69 one-time for up to 3 Macs with every future version; Commercial $49 per seat per year. Details: https://minpinproxy.com/pricing.md
- Privacy: captured traffic stays on the Mac. The root CA key is generated locally (0600) and never leaves the device. HTTPS is only decrypted for hosts the user enables.
- Proxy address: 127.0.0.1:8080 by default (falls back to 8081-8090 if the port is taken).

## Guides

- [Inspect iOS Simulator network traffic on a Mac](https://minpinproxy.com/guides/inspect-ios-simulator-traffic): trust the CA, install it in the Simulator, decrypt per host
- [Let Claude Code, Cursor or VS Code read your HTTP traffic](https://minpinproxy.com/guides/ai-assistant-read-http-traffic): enable the MCP server and connect a client
- [Debug WebSocket traffic on macOS](https://minpinproxy.com/guides/debug-websocket-mac): read frames live, pause, edit or drop them
- [Mock an API response without changing your code](https://minpinproxy.com/guides/mock-api-response-mac): Map Local, breakpoints, rewrite rules, Map Remote
