What is Stay Awake?

Stay Awake is a free, browser-based mouse jiggler and screen wake tool. It prevents your Mac or Windows computer from going to sleep, stops the screensaver from activating, and keeps your Microsoft Teams or Slack presence showing as Available — all without any software to download or install.

It works using several techniques at once: the browser's native Screen Wake Lock API, periodic invisible mouse and scroll activity events that reset the OS idle timer, and a silent background audio and video loop that keeps the browser classified as active media. You can also set a custom auto-stop timer so the tool shuts down exactly when you need it to.

It's also the perfect tool for keeping a program or script running in the background. Start a large download, a video render, a backup, a build or a long-running script, switch on Stay Awake, and get on with your day — no more worrying that your computer will fall asleep or shut off halfway through.

Who is it for?

  • Remote workers who need to stay active on Teams or Slack during breaks
  • Anyone whose screen turns off during presentations, long reads, or background tasks
  • Developers and power users running scripts, builds, downloads or renders that need to finish without the computer going to sleep
  • People on managed work laptops where IT has locked screensaver settings
  • Anyone looking for a free online mouse jiggler — no USB device or install required

How to keep Microsoft Teams status active

Microsoft Teams switches your status to "Away" after roughly 5 minutes of system inactivity. Stay Awake resets that idle timer every 45 seconds by simulating invisible mouse movement and scroll events — keeping Teams showing you as Available for as long as the tool is running.

Unlike physical USB mouse jigglers, Stay Awake runs entirely in your browser on both Mac and Windows. No admin rights, no hardware, no installation needed.

Does it work for Slack too?

Yes. Slack uses the same OS-level idle detection as Teams. Stay Awake prevents that idle timer from triggering, so your Slack status stays green automatically alongside Teams.

Will it work on my work laptop?

In most cases, yes. The activity simulation works on virtually all managed devices since it operates at the browser level. The Screen Wake Lock API may occasionally be restricted by strict IT Group Policy, but the nudge, audio and video loop combination still prevents sleep on most corporate machines.
