Discord RAM Limiter

Discord RAM Limiter is a small Windows desktop app that monitors Discord memory usage and can trim Discord's working set while it runs in the background.

The app uses the native Windows SetProcessWorkingSetSize(process.Handle, -1, -1) call on detected Discord processes when the limiter is enabled.
