SlideX (slide-express)

SlideX (slide-express) is a lightweight Express application that allows you to control presentation slides over WiFi using any remote device such as a smartphone or tablet.

It runs a small local web server on your machine, generates a QR code, and provides a web-based remote control interface that works within your local network—effectively turning your phone into a wireless presentation clicker.
