The record

Product: Probe is a local HTTP/HTTPS debugging proxy and API client for inspecting app traffic, mocking APIs, and automating requests.
Traffic capture: It captures and decrypts HTTP/HTTPS requests from iPhone, Android, simulator, desktop apps, and terminal clients, showing headers, bodies, and timing.
Response editing: Breakpoints let users pause requests or responses, edit headers and bodies, then continue or abort.
Mocking and routing: Map Local can answer matching URLs with a local file or inline body, while Map Remote can forward them to another host.
Automation: Visual flows can chain requests, extract values, assert on results, branch, loop, and run from the app, REST API, MCP, or headless CLI.
API client: The client supports HTTP and GraphQL, collections, environments, auth, and history; it imports cURL or Postman and exports to Postman v2.1.
AI integrations: Probe has a built-in MCP server for Claude Code, Cursor, Codex, and other compatible clients to inspect and replay traffic and manage mocks and flows.
Other integrations: Probe lists file browsing and transfers over SFTP, FTP/FTPS, S3, and WebDAV.
Security and privacy: The privacy policy says captured traffic and session data stay on the device, private CA keys never leave it, and Probe does not collect analytics or require an account.
HTTPS security detail: Probe performs HTTPS interception using a locally generated CA, so it can see decrypted traffic routed through it; the policy says that data is not transmitted elsewhere.
Setup limitation: HTTPS inspection requires installing and trusting Probe’s CA certificate on each device; Android 7+ only trusts user-installed CAs for apps that opt in.
Desktop support: Probe’s desktop app supports macOS 12+ on Apple Silicon or Intel and Windows 10+.
Support: The documentation directs users who cannot find an answer to open a GitHub issue, and the privacy policy lists an email contact for policy questions.
