Probe Documentation

HTTP/HTTPS debugging proxy. Install in a minute, capture in five.

Get up and running

Introduction What Probe is, who it's for, and the three-column UI you'll work in.

Certificate Setup Install and trust the CA on macOS, Windows, iOS, and Android — required for HTTPS.

Mobile Debugging Point your iPhone or Android at Probe and capture every request the app makes.

Capturing Traffic How HTTPS interception works, plus Sequence vs Structure views and Domain Watch.

Composer Build, send, and save HTTP requests. Collections, environments, auth, cURL import.

Map Local Serve a canned response from disk without ever contacting the origin server.

Map Remote Rewrite a URL to a different upstream — point a mobile build at staging.

Breakpoints Pause requests or responses in flight, edit the bytes, then continue.

Scripting Run JavaScript on every matching request with the pro global — crypto, assertions, env.

MCP Server Plug Claude Code, Cursor, or any MCP client into Probe to inspect and replay traffic.

Reference Keyboard shortcuts, settings, REST API, file format, and troubleshooting.
