Software vs. hardware mouse jiggler

Two ways to keep a computer awake — here's how to choose.

Every mouse jiggler falls into one of two camps: a software app that runs on your computer, or a hardware device you plug in. Both keep your machine active, but they trade off cost, convenience, and how visible they are to monitoring software. Here's a straight comparison so you can pick the right one.

Software mouse jigglers

A software jiggler is a small program that periodically moves your cursor or sends a keystroke. Examples range from open-source tools to the free randomized jiggler on our homepage.

Pros:

• Free. Almost all software jigglers cost nothing.
• Instant. Download and run in seconds — no waiting for shipping.
• Flexible. Good ones let you tune the timing and movement, and some offer randomized, human-like patterns.

Cons:

• It's a process on the PC. Advanced endpoint-monitoring agents that inventory running programs could potentially detect it (see our guide on whether jigglers are detectable).
• Admin restrictions. Locked-down work laptops may block you from running unapproved software.

Hardware mouse jigglers

A hardware jiggler is a physical device. There are two main types: a USB dongle that emulates a mouse and sends tiny movements, and a mechanical mover — a little motorized pad your real mouse sits on that physically nudges it.

Pros:

• Invisible to software. Because the movement comes from an external device, there's no program on your PC to detect. This is the most robust option against process inspection.
• No install needed. USB dongles are plug-and-play; mechanical movers don't even connect to the computer.
• Works on locked-down machines. A dongle looks like an ordinary mouse, so it works even where you can't install software.

Cons:

• Costs money. Typically $8–20 for a dongle, a bit more for a mechanical mover.
• You have to buy and wait for it. No instant gratification.
• Physical presence. It's a device on your desk someone could notice in person.

Our take

For most people, start free: try the browser keep-awake tool or the free software jiggler. If you hit a wall — a work laptop that blocks installs, or a monitoring setup you're genuinely worried about — a cheap USB dongle is the natural upgrade. There's rarely a reason to spend more than $20.
