Moni Proxy

Overview

Moni Proxy is a device-based tool for inspecting and testing HTTP/HTTPS traffic. It is best suited to mobile developers and QA engineers who need to diagnose or alter app requests on a local network. Its combination of capture, replay, and traffic rules is useful for focused testing, though the Free plan’s quotas and the uneven desktop rollout narrow its reach.

Key features

After a guided local certificate-authority setup, Moni Proxy decrypts HTTP and HTTPS calls and shows their method, status, host, path, size, and duration. This makes it practical to trace app-to-API behavior, while the certificate setup is a necessary part of inspecting encrypted traffic.

Rules support local response mocks, request rewrites, DNS overrides, block lists, and breakpoints. Free allows one active mock, rewrite, and breakpoint rule, plus three DNS overrides and three ignore-host rules. Those limits can cover a small test case, but broader scenarios will push users toward a paid plan. Compose can build requests or edit a captured request’s method, URL, headers, and JSON body before replaying it.

JSON responses can generate typed models in Swift, Dart, Kotlin, and TypeScript. The Toolbox also includes JSON formatting, Base64 and URL encoding, hashes, JWT decoding, QR generation and scanning, timestamps, and a regex tester. Free exports are limited to HAR, and history lasts seven days; Pro adds cURL, .moniproxy, and multi-session exports, alongside unlimited history.

Devices pair by QR code or host and port over a local network. The maker says capture, SSL decryption, mocking, and scripting run locally, without sending request payloads or decrypted traffic to its servers. Rooting or jailbreaking is not required: Moni Proxy uses native VPN profiles and certificate configurations to route and parse traffic.

Pricing

The Free Plan costs nothing. 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 reasonable way to assess the workflow, but the request quota, single-device cap, and narrower export options limit sustained or collaborative use.

Paid plans are perpetual licenses with one year of updates. Desktop costs $71, paid once for one device, with macOS, Windows, and Linux coverage, all Pro features, personal and commercial use, and a transferable license. It fits a single-device user who wants the Pro feature set; it does not cover mobile devices.

Multi-Device costs $79, paid once and covers three devices: one desktop, one iOS, and one Android device. It includes all Pro features, personal and commercial use, a transferable license, and one year of updates. For only 8.00 USD more than Desktop, it is the better fit for an individual testing across desktop and both major mobile platforms.

Team 5 costs $129, paid once for five seats; Team 10 costs $229, paid once for ten. Each seat covers desktop, iOS, and Android, with centralized seat management, priority email support, and one year of updates. These plans suit teams that need managed seats across platforms; solo users do not need to pay for that capacity.

Platforms

iOS, Android, and macOS downloads are offered. Windows and Linux desktop releases are marked as Phase 2 and coming soon, despite appearing in the Desktop plan’s platform coverage. The iOS app requires iOS 15.0 or later, and the Android app requires Android 8.0 or later. Buyers who need Windows or Linux now should not rely on the stated plan coverage as evidence that those releases are ready.

Who it's for

Moni Proxy is aimed at mobile and API developers, QA and test engineers, and security testers inspecting apps they are authorized to test. Its local capture and request controls are especially relevant when a test depends on examining, changing, or replaying device traffic. It is a weaker fit for users who need broad rule sets on the free tier or an available Windows or Linux desktop release today.

Pros and cons

• Pros: Local capture and decryption keep inspection and testing on the device rather than sending traffic to the maker’s servers, according to the maker.
• Pros: Mocks, rewrites, DNS overrides, blocks, breakpoints, and replay bring several useful testing controls into one workflow.
• Pros: Multi-Device covers desktop, iOS, and Android for one-time payment, with a transferable license and one year of updates.
• Cons: Free users are limited to one paired device, 20 Compose requests per day, seven-day history, and one active rule of several types.
• Cons: Windows and Linux desktop releases are coming soon, which makes current desktop availability less consistent than the plan names suggest.
• Cons: Free includes Dart model generation, while Swift, Kotlin, and TypeScript generation are not included in its stated feature allowance.

Alternatives

Web Debugging Proxies is the broader directory for comparing tools in this category. Consider HTTP Toolkit if its free plan’s manual request and response breakpoints and built-in HTTP client tools better match your inspection workflow; it also supports web alongside desktop and mobile platforms. Fluxzy is worth comparing if you want a free community edition with all features included for personal use, or need its broader platform range, including API and self-hosted options. Reqable may suit readers who prefer its Community allowance of one device, 100MB storage, and three rewrite, script, breakpoint, gateway, and mirror rules. mitmproxy is the alternative to consider for a free, open-source interactive HTTPS proxy. NetworkSpy may be relevant if its free plan’s limited LLM token stream analysis, breakpoints, resource mapping, custom viewer builder, and scripting are closer to your needs. Mediator is a free, Apache-2.0-licensed cross-platform GUI gRPC debugging proxy. WePROXA is another freemium option for macOS and Windows users. Whistle is a free alternative spanning desktop, mobile, and web platforms.

Verdict

Choose Moni Proxy if you need local mobile-traffic inspection with request editing, replay, and practical rule-based testing, especially across desktop and iOS or Android devices. Its all-platform individual license is a straightforward way to expand beyond the constrained Free plan. Look elsewhere if you need a ready Windows or Linux desktop app now, or if free-tier rule and usage caps would interrupt your work.
