Features
Everything you need to debug HTTP/HTTPS traffic from any device on your network.
HTTPS Interception
Full man-in-the-middle proxy with auto-generated certificates. Trusted by iOS, macOS, Android, and Windows — no manual CA setup headaches.
Mobile Device Debugging
Inspect HTTP/HTTPS traffic from iPhones, iPads, and Android devices connected to your local network. See every request in real-time.
Built with Rust
The proxy core is written in Rust for maximum performance. Handles thousands of concurrent connections with minimal CPU and memory usage.
Breakpoints
Set breakpoints on requests or responses by URL pattern. Inspect, edit headers and body, then resume — perfect for testing edge cases.
JavaScript Scripting
Write scripts to automate request/response modification. Built-in QuickJS engine with crypto utilities, assertions, and dynamic variables.
Request Composer
Build and send HTTP requests from scratch. Organize into collections, use environment variables, import from cURL or Postman.
Domain Watch
Focus on the domains that matter. Unwatched domains show a summary; watched domains show every request. Reduce noise instantly.
Sessions
Save captured traffic as sessions for later analysis. Export and import session files to share with your team.
Structure View
Group requests by domain and URL path in a tree view. Quickly navigate complex API hierarchies instead of scrolling a flat list.
AI Integration (MCP)
Built-in MCP server with 61 tools for AI-powered debugging. Connect Claude Code, Cursor, or any MCP-compatible AI agent to inspect traffic, replay requests, set breakpoints, run scripts, create Map Local / Map Remote rules, and analyze API behavior — all from your AI workflow.
Map Local
Mock any endpoint with a local file or inline JSON/XML/HTML body. Wildcard URL patterns, custom status code + headers, and simulated latency — perfect for building a client against an API that does not exist yet.
Map Remote
Redirect matching requests to a different upstream. Point a mobile build at staging, swap a CDN for the real origin, or send production traffic to localhost — all with path wildcards and an optional preserve-Host-header toggle for SNI-routed load balancers.
Network Throttling
Global profiles (3G, LTE, offline) plus scoped per-rule throttling targeted at a single host, URL glob, or app. Test how your app handles latency, bandwidth limits, and packet loss without reproducing the network yourself.
Pre-configured Terminal
Launch Terminal.app or iTerm2 already routed through Probe. curl, python, ruby, go — every HTTP client from that shell is captured. A bundled Node shim (global-agent + vendored undici) covers axios, got, node-fetch, and native fetch() with zero npm setup.
Filter Folders
Create saved filter folders to quickly isolate traffic by domain, method, status code, or custom criteria.
Multilingual
Full localization support. Available in English, Japanese, and Vietnamese with more languages coming.
