Proxee

Proxee is a macOS menu bar app designed for web developers who want to preview and interact with their local development server directly on an iPhone. It transforms the way developers test mobile UIs by syncing the localhost environment to a physical iOS device in real time. The core value lies in eliminating the guesswork from responsive design: what you see on your Mac is exactly what appears on your phone, with no deployment or cloud tunnel required. Proxee is built for frontend engineers, designers, and anyone who needs to catch mobile UI bugs before shipping to production. By providing a seamless, zero-configuration bridge between a Mac and an iPhone, it makes mobile preview part of the development workflow rather than an afterthought.

The primary problem Proxee solves is the disconnect between desktop development and mobile testing. Developers often code on a large screen, then deploy or use emulators to check the mobile experience, missing subtle layout shifts, touch interactions, or scroll behavior that only appear on real hardware. Frequent device unlocking, switching between tools, and manual page navigation waste time and break focus. Proxee addresses these pain points by keeping the iPhone screen awake, syncing scroll position, and reloading pages automatically when code changes. This continuous, always-on preview ensures that mobile UI bugs are caught instantly, reducing the iteration cycle from minutes to seconds and preventing broken layouts from reaching users.

Live Reload & Scroll Sync is Proxee's first major feature group. When you make changes to your code, the paired iPhone automatically reloads the page, reflecting updates immediately. Simultaneously, scroll position is synchronized, so both devices stay aligned as you navigate or scroll. This works because Proxee injects a small client script that listens for dev server events. The benefit is that developers no longer need to manually refresh the iPhone after every edit or hunt through long pages to find the same content. It keeps the testing flow continuous, allowing rapid iteration on responsive designs and ensuring that UI components render correctly at every viewport position.

Native iPhone Companion is the second key feature group. Proxee includes a free iOS app available on the App Store that keeps the iPhone screen awake during development sessions, preventing the device from locking and interrupting the preview. The companion also remembers the Proxee session, so reconnecting after a break is seamless. For quick checks, any iOS browser can be used, but for extended work, the companion app adds reliability. It integrates with the iPhone‘s native behavior, including QR code scanning for initial pairing, trusted device recognition, and automatic reconnection. This makes the preview feel like a native part of the development environment rather than a makeshift solution.
