Probe
HTTP/HTTPS debugging proxy for macOS and Windows.
Inspect traffic from iPhones, Android devices, and desktop apps.
Everything you need to debug traffic
Powerful features for inspecting, modifying, and testing HTTP/HTTPS requests from any device.
HTTPS Interception
Full man-in-the-middle proxy with auto-generated certificates. Trusted by iOS, macOS, Android, and Windows.
Mobile Device Debugging
Inspect HTTP/HTTPS traffic from iPhones, iPads, and Android devices connected to your local network.
Built with Rust
High-performance proxy core handles thousands of concurrent connections with minimal CPU and memory.
Breakpoints
Pause requests or responses by URL pattern. Inspect, edit headers and body, then resume.
JavaScript Scripting
Automate request/response modification with built-in QuickJS engine, crypto utilities, and assertions.
Request Composer
Build and send HTTP requests. Organize into collections, use environments, import from cURL or Postman.
Domain Watch
Focus on domains that matter. Unwatched domains show a summary; watched domains show every request.
Sessions
Save captured traffic as sessions for later analysis. Export and import to share with your team.
Structure View
Group requests by domain and URL path in a tree view. Navigate complex API hierarchies easily.
AI Integration (MCP)
Built-in MCP server with 54 tools. Let Claude, Cursor, or any AI agent inspect, replay, and debug your traffic.
Map Local
Mock any endpoint with a local file or inline body. Wildcard URL patterns, custom status + headers, simulated latency.
Network Throttling
Global profiles (3G, LTE, offline) plus scoped rules per host / URL glob / app. Test how your app handles limits.
Pre-configured Terminal
One click opens Terminal.app or iTerm2 already routed through Probe — curl, python, node all captured, with a bundled Node shim covering axios, got, and native fetch().
Filter Folders
Create saved filter folders to quickly isolate traffic by domain, method, status code, or custom criteria.
Multilingual
Available in English, Japanese, and Vietnamese with more languages coming.
