No PowerToys installation required. Just download, pick a spot or an area, and go.
Green Dotter is available two official ways: install from the Microsoft Store, or download it directly from green-dotter.com. No account, email address or subscription is required.
Pick a mode and press Start. Nothing to configure first.
Choose one exact spot, or draw a box and it clicks somewhere inside it. Clicks land at random intervals inside the range you set, so the rhythm isn't mechanical.
Nothing to pick. The mouse drifts a little, the way yours does while you read. Choose how long, press Start, and leave it.

Touch the mouse and it pauses, then carries on once you stop. While it runs it folds down to a small bar you can park in a corner.
Pick your days and hours, add a lunch break. Start and stop times shift by a few minutes each day, so it isn't clocking in at 9:00 sharp.

Green Dotter has to be open, the tray is fine, and your computer on and signed in. It can't wake a sleeping computer. It's new, so if something looks off, tell us.
PowerToys Awake keeps your computer from sleeping, but it's buried inside a 50MB developer toolkit you probably don't need. Green Dotter does the same job and more, as a standalone 3.5 MB app with nothing else bundled in.
| Green Dotter | PowerToys Awake | |
|---|---|---|
| Human-style wiggle mode | ✓ | ✗ |
| File size | ~3.5 MB | ~50MB (full PowerToys) |
| Standalone app | ✓ | ✗ Bundled with PowerToys |
| Keeps computer awake | ✓ | ✓ |
| Simulates mouse activity | ✓ | ✗ |
| Helps keep Slack/Teams status active | ✓ | ✗ |
| Mac support | ✓ | ✗ Windows only |
| Free | ✓ | ✓ |
Both keep your machine awake and both are free. The difference is everything around it: Green Dotter is one small app that also helps keep your Teams status active and helps stop Slack going idle, on Mac as well as Windows.
You don't need the rest of PowerToys. PowerToys is a great toolkit for developers. If all you want is to keep your computer awake, it's overkill. Green Dotter is just the one tool, nothing else.
It helps keep your status active too. PowerToys Awake prevents sleep but doesn't simulate mouse movement. Green Dotter clicks in areas you define, which can help keep your status from going idle in apps like Slack and Teams. The full story is in the PowerToys Awake explainer.
Works on Mac and Windows. PowerToys is Windows only. Green Dotter works on both. If you just need sleep prevention, see the broader guide to keeping your computer awake. On a Mac, start with the auto clicker for Mac page.
