Moni Proxy

Moni Proxy captures and inspects HTTP/HTTPS traffic on devices, with tools to mock responses, rewrite requests, and replay captured traffic. It displays request details such as method, status, host, path, size, and duration. HTTPS inspection requires a guided local certificate authority setup. Rules can also override DNS, block traffic, and pause at breakpoints; the free tier permits one active rule of each type. Compose lets users build requests by editing the method, URL, headers, and JSON body. The app can generate typed models from JSON responses in Swift, Dart, Kotlin, and TypeScript, and its Toolbox includes utilities for JSON, encoding, hashes, JWTs, QR codes, timestamps, and regular expressions.

The free plan includes 20 Compose requests per day, seven-day history, one paired device, Dart code generation, and HAR export. Paid plans start at $71, paid once. The maker says traffic processing happens locally and payloads are not sent to its servers. iOS, Android, and macOS downloads are listed; Windows and Linux releases are marked as coming soon.

Moni Proxy combines traffic inspection with request editing, rules, and replay, alongside code generation and utility tools. Check the platform availability and free-tier limits against your needs before choosing a plan.

Moni Proxy is intended for mobile and API developers, QA and test engineers, and security testers inspecting apps they are authorized to test. It suits people who need to inspect, alter, mock, or replay device traffic.

Overview

Moni Proxy is a device-based HTTP/HTTPS traffic inspector and testing tool for mobile and API developers, QA engineers, and security testers working on apps they are authorized to inspect. Its strongest case is local capture paired with request editing, replay, and traffic rules; the trade-off is a tightly capped free tier and uneven desktop availability.

Key features

After a guided local certificate-authority setup, Moni Proxy decrypts HTTP and HTTPS calls and shows each request’s method, status, host, path, size, and duration. That visibility can help trace app-to-API behavior without sending decrypted traffic to the maker’s servers: the maker says capture, decryption, mocking, and scripting all run locally. HTTPS inspection does require configuring a certificate on the device.

The rules engine combines local response mocks, request rewrites, DNS overrides, block lists, and breakpoints. Free allows one active mock, rewrite, and breakpoint rule, alongside three DNS overrides and three ignore-host rules. Those limits suit a focused debugging task, but they constrain broader test scenarios. Compose can build or edit a request’s method, URL, headers, and JSON body, then replay captured requests; its 20-request daily allowance on Free makes it less suitable for repeated use throughout a busy workday.

JSON responses can generate typed models in Swift, Dart, Kotlin, and TypeScript. The Toolbox adds JSON formatting, Base64 and URL encoding, hashes, JWT decoding, QR generation and scanning, timestamps, and regex testing. Free exports are limited to HAR and history lasts seven days. Pro expands exports to cURL, .moniproxy, and multi-session formats, removes the history limit, and supports up to five paired devices instead of one.

Moni Proxy says it routes traffic through native system VPN profiles and certificate configurations, without requiring Android root or an iOS jailbreak. That lowers a common barrier to device inspection, though certificate setup remains part of the HTTPS workflow.

Pricing

Free Plan: free. It includes one active mock, rewrite, and breakpoint rule each; 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. It is a useful way to assess the workflow, but the rule, request, history, and device caps limit sustained or multi-device work.

Desktop: $71, paid once, a one-time payment for a perpetual license on one device. It includes all Pro features, personal and commercial use, a transferable license, and one year of updates. This is the simplest paid fit for an individual working on one desktop, but it does not include mobile-device seats.

Multi-Device: $79, paid once, a one-time payment for a perpetual license covering three devices: one desktop, one iOS device, and one Android device. It includes all Pro features, personal and commercial use, a transferable license, and one year of updates. For a modest step up from Desktop, it is the more practical choice for developers checking traffic across platforms.

Team 5: $129, paid once for five seats, with desktop, iOS, and Android per seat, centralized seat management, priority email support, and one year of updates. Team 10: $229, paid once for ten seats with the same platform coverage and support terms. Both are perpetual licenses; they suit teams that need managed access across devices rather than a collection of individual licenses.

Platforms

The iOS app requires iOS 15.0 or later, and the Android app requires Android 8.0 or later. A macOS installer is available. Windows and Linux desktop releases are labeled Phase 2 and coming soon, so buyers who need either desktop version now should not rely on Moni Proxy for that workflow.

Who it's for

Moni Proxy is best suited to mobile and API developers, QA and test engineers, and security testers inspecting apps they are authorized to test. Its combination of device capture, editing, mocks, and replay is relevant when debugging behavior on iOS or Android. It is a weaker fit for users who need Windows or Linux desktop support immediately, or who need more than the Free plan’s daily Compose and active-rule allowances.

Pros and cons

• Pros: Local capture and decryption keep request payloads off the maker’s servers, according to the maker, which is a meaningful advantage for sensitive test traffic.
• Pros: Editing, replay, breakpoints, DNS overrides, and local mocks cover several common debugging and test tasks in one tool.
• Pros: The Multi-Device perpetual license covers desktop, iOS, and Android for $79, paid once, making cross-platform individual use more practical than the one-device Desktop plan.
• Cons: Free is capped at 20 Compose requests per day, one paired device, and seven-day history, limiting it as a full-time workflow.
• Cons: Windows and Linux desktop releases are still marked as coming soon, narrowing its present desktop reach.
• Cons: Paid perpetual licenses include only one year of updates, so buyers should factor that term into their longer-term plans.

Verdict

Choose Moni Proxy if you need local mobile traffic inspection together with request editing, replay, and rules, especially across desktop, iOS, and Android under one individual license. Its local-processing approach and useful testing toolkit are the main reasons to consider it. Look elsewhere if you need a Windows or Linux desktop release now, or if the Free plan’s daily request and history caps are too restrictive for your work.
