I’m a solo macOS developer and I built Mocksy, a small native app for quickly mocking API endpoints on your Mac. I made it because I often needed simple mock responses while building macOS and iOS apps, but existing tools felt too heavy, required config files, or didn’t integrate smoothly into a local Apple-dev workflow.

Mocksy lets you spin up local HTTP endpoints in seconds, return custom JSON responses without running a backend, test UI states offline, and prototype features without dealing with servers. The goal is to keep it minimal, fast, and unobtrusive.
