100% virus-checked | No installation or admin rights required

What is the anti-standby tool?

It is a standalone, Python-based program (compiled as a single portable .exe file) for the intelligent simulation of user activity. In the background it makes minimal mouse and keyboard movements, opens and controls the Edge browser in the foreground on request, and so reliably prevents Windows from switching to power-saving mode or the lock screen.

Main features at a glance

Multi-monitor support

Detects all connected displays for targeted actions.

Edge in the foreground

The browser window is positioned and maximised automatically.

First call guaranteed

Loads a fixed URL at start (e.g. robutech.ch), then random pages.

Automatic WebDriver

The matching Edge driver is downloaded automatically in the background.

Configurable URL list

Manage your preferred websites via file or the built-in GUI.

Random intervals (jitter)

Variable delays make the behaviour appear entirely human.

WinAPI sleep prevention

Uses native system calls – transparent and highly efficient.

Intuitive GUI (Tkinter)

A clear interface for starting and stopping within seconds.

Logging & debug mode

Live logging of all simulated actions for maximum transparency.

Standalone application
