Introduction

Proxyman is a native macOS app for capturing, decrypting and mocking HTTP and HTTPS requests and responses. Its homepage calls it a ‘best-in-class native macOS app’ and stresses Apple Silicon performance.

Testers and mobile developers use it to inspect traffic from macOS apps, iOS simulators and devices, and Android devices; to set breakpoints and modify requests on the fly; to map responses to local files or remote URLs; and to script traffic changes in JavaScript. The site also says AI agents can read the traffic Proxyman captures.

Licences are a one-time purchase with a year of updates (continued use of the last version afterwards) or a yearly subscription.

In the quality loop it supports debugging and manual testing of client-server traffic, especially for Apple platforms.

Features

1. HTTPS decryption: Inspect encrypted traffic with certificate setup helpers.
2. Breakpoints: Pause and edit requests and responses.
3. Map Local and Remote: Mock responses from files or other hosts.
4. Scripting: JavaScript to modify traffic.
5. Mobile debugging: iOS and Android device and simulator support.

Pros
