Show HN: Lynk – Real-time and daily app updates via websockets (macOS, no SDKs)

Hi hackers!

I'm a self-taught solo teenage dev

ever wanted to show what you're doing right now on the internet?

well I've been wanting to for a while, so I built Lynk, a lightweight macOS app that tracks your active apps, window titles, and daily usage in real time, and broadcasts that data over WebSockets. Oh and it also updates whenever you switch apps to connected clients!

No SDKs, no APIs — just local tracking + a websocket endpoint you can ping from any language.

Does it track only the currently focused app, or does it collect background activity too? Wondering how invasive it might feel in day-to-day use.

+ its not very invasive, for me it just launches at startup and thats it, no notifications, alerts, or anything

it only tracks the name of what window ur in currently
