Fast Mouse Clicker vs. Sourceforge Auto Clicker vs. The Fastest Mouse Clicker for Windows

Fast Mouse Clicker was quite a mature app, but it is a completely abandoned project since 2016. The app simulated left, middle or right mouse clicks. It could automatically stop at a certain number of clicks.

Sourceforge Auto Clicker is still mature and alive. Sourceforge Auto Clicker is an app with two modes of auto-clicking, at your dynamic cursor location or at a pre-specified location. The maximum amounts of clicked can also be set (or left as infinite). Hotkeys work in the background for convenience.

Interesting fact, Sourceforge Auto Clicker is a subset of OP Auto Clicker, as OP Auto Clicker is a collection of several different programs for various platforms, most of which are closed-source and should be considered with caution. So we provide an advanced, professional, modern fork of OP Auto Clicker called OP AutoClicker Record Play for Windows (AutoClicker2 Record Play).

Speed AutoClicker vs. Terminator vs. The Fastest Mouse Clicker for Windows

Speed AutoClicker is a relatively new app and it allows you to set an activation key to switch automatic clicking . There are two activation modes: “hold”: Speed AutoClicker will repeat clicking as long as the activation key is pressed “toggle”: First key press will activate automatic clicking until the activation key is pressed again, so independent trigger keys in toggle mode are not supported.

Terminator is a new attempt to write an auto-clicker. It provides the toggle mode effortlessly with keyboard or mouse buttons. It has aesthetic console UI and works discreetly in the background.
