About

Built to solve a problem.
Then kept going.

LanChGo started as a personal tool and grew into something worth sharing — fast, private, offline-first LAN communication.

The Story
Why LanChGo exists.

Honestly? Because I was tired of the friction. Every messaging tool wanted me to sign in, connect to the internet, install something, or create an account just to send a message to someone sitting next to me on the same network. That felt wrong.

So I built LanChGo — a tool that just works. Open it, pick your network, and start chatting. No sign-ins, no clutter, no tracking. What started as a personal utility became something I wanted to share.

I built the Windows version using Rust for the backend and Slint for the UI, and the Android app separately. Future updates will keep adding features while preserving what makes it great — speed and simplicity.
