FiddlerCore vs Moni Proxy

FiddlerCore has no write-up on Specifiction yet; its figures are above.

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.
