When your memory fills up, he makes sure you notice.

A door opens. A dark figure steps out. A card tells you what to close. When memory drops, he goes home.

Shadow Form · walks out A demo of the sequence. The app uses your real memory.

What it does

1

Under 80%, nothing happens.

He stays out of your way.

2

At 80% or more, the door opens.

The room darkens and he steps out. A card lists the programs using the most memory, and repeats every 5 minutes while memory stays high.

3

Under 75%, he goes home.

The gap between 80 and 75 is on purpose, so he does not flicker in and out.

Real numbers, not guesses

A web page cannot see your whole computer. So a small helper program on your computer shares the real memory use and the biggest programs with the page.

On your desktop

A web page lives inside its browser window. The Windows desktop app goes further: the screen darkens, the door opens in the corner, and he steps out over whatever you were doing. The mouse goes straight through to your work, and only the card takes clicks. It reads your memory itself, so it needs no helper and no account.

It is in the desktop/ folder, and its README explains how to run it and build the installer.
