synkin - preview website on phone with usb

🚀 I built Synkin — a free, open-source npm CLI that lets you preview localhost websites directly on your Android device over USB.

I built it because I was tired of:

• Setting up local IPs every time
• Connecting both devices to the same Wi-Fi
• Running into localhost/backend API issues while testing

With Synkin, just connect your Android phone via USB and run:

synkin run

That's it. Your website opens automatically in Chrome, and backend APIs continue to work using ADB Reverse.

Features

• ⚡ One-command setup
• 📱 Real Android device testing
• 🔌 USB connection (no Wi-Fi required)
• 🌐 Backend API support
• 🚀 Supports React, Vite, Next.js, Express, FastAPI, Flask, Django & Static HTML

The project has already crossed 850+ npm installs, and I'm ac

tively improving it based on community feedback.

I'd love to hear your thoughts, feature requests, or contributions!
