Fiddler Everywhere vs Moni Proxy

Fiddler Everywhere captures, inspects, modifies, and replays HTTP/S traffic across applications, services, and devices. Capture options include system proxy, network, browser, and terminal modes. It decodes HTTP/2, SignalR, WebSockets, MessagePack, SSE, gRPC, and Protobuf. Users can compose API requests, replay traffic, set breakpoints, and create rules that change requests or responses. Its MCP server connects to coding assistants and agent-powered IDEs, with setup documented for VS Code, Cursor, Claude Code, GitHub Copilot CLI, and Codex CLI. Output sanitization can remove sensitive information before data is shared with a model. The product is aimed at developers, QA staff, and support engineers. Desktop downloads are listed for Windows 10 and 11, macOS 11 or later on Intel or Apple Silicon, and Ubuntu 20 or later; Android and iOS are also listed as platforms. A 10-day trial is available, but there is no free plan. Lite costs $10 a month and Pro $19 a month, both billed monthly; Enterprise costs $37 a year, billed annually.

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.
