Moni Proxy vs Probe

Moni Proxy captures and works with HTTP/HTTPS traffic on devices, letting developers inspect, mock, rewrite, and replay requests. For HTTPS, it decrypts calls after a guided local certificate authority setup and displays each request’s method, status, host, path, size, and duration. Its rules can map local responses, rewrite requests, override DNS, block traffic, or pause at breakpoints. Compose lets users build or edit a request’s method, URL, headers, and JSON body before replaying it. The tool also generates typed models from JSON in Swift, Dart, Kotlin, and TypeScript, and includes utilities for JSON, encoding, hashes, JWTs, QR codes, timestamps, and regular expressions.

The free plan costs nothing and includes one active rule each for mocks, rewrites, and breakpoints, three DNS override rules, three ignore-host rules, 20 Compose requests per day, seven-day history, one paired device, Dart code generation, and HAR export. Paid plans start at $71, paid once. iOS and Android apps and a macOS installer are listed; Windows and Linux desktop releases are marked as coming soon.

Probe is a local HTTP/HTTPS proxy and API client for examining application traffic, editing requests and responses, creating mocks, and automating requests. It can capture traffic from phones, simulators, desktop apps, and terminal clients, then show headers, bodies, and timing. Breakpoints let users pause a request or response, change its headers or body, and continue or abort it. Map Local serves a local file or inline body for matching URLs; Map Remote forwards them to another host. Visual flows can chain requests, extract values, check results, branch, and loop, and run in the app, through REST API or MCP, or with a headless CLI. The API client supports HTTP and GraphQL, collections, environments, authentication, and history. It imports cURL or Postman and exports to Postman v2.1. Probe also includes an MCP server for compatible clients and file browsing and transfers over SFTP, FTP/FTPS, S3, and WebDAV. It is available for Android, iOS, macOS, Windows, and API use. The free plan costs nothing.
