The Fastest Mouse Clicker for Windows
The fastest auto-clicker for Windows PC. 100000 clicks per second by arrays in Win32 SendInput() API. Classic Windows 64-bit and cross-platform Windows edition
Updated : May 27 2026.
2026 is the project’s 10th anniversary
Quick Start
The Fastest Mouse Clicker for Windows cross-platform is the most advanced, high-performance automation utility engineered for Windows 10 and 11 (and unofficially for Windows 7). Built on a low-latency C++/Qt framework, The Fastest Mouse Clicker for Windows cross-platform utilizes the Win32 SendInput() API (the cross-platform version 3 achieves that via libuiohook library) to bypass standard software bottlenecks, delivering record-breaking click speeds that exceed 100,000 clicks per second (CPS).
To ensure compatibility with modern games and applications like Minecraft or Roblox, The Fastest Mouse Clicker for Windows cross-platform includes advanced “Humanization” algorithms:
- Randomized Time Intervals: Set a variance range (e.g., 0% to 50% compared to your selected average interval) to mimic human clicking patterns and bypass basic auto-clicker detection.
- Randomized Coordinate Offsets: Add slight pixel-randomization (e.g., 0px to 50px) to your click location to prevent “static-click” flagging in Minecraft, Roblox.
The Fastest Mouse Clicker for Windows Classic is the original, battle-tested Windows-only edition of one of the most popular open-source auto-clickers in the world - with over 183 GitHub stars. It is a single self-contained 64-bit native Win32 application, statically linked with zero external runtime dependencies, and engineered to push mouse-click automation to the absolute hardware limit.
The secret behind its record-breaking throughput is a carefully crafted use of the Win32 SendInput() API with the input event arrays. Rather than issuing one synthetic mouse event per system call, the application batches hundreds of INPUT structures into a single SendInput() call, saturating the OS input queue and achieving verified click rates of up to 100,000 clicks per second (CPS) - a result no conventional auto-clicker can match.

Technology overview; what is Windows-specific
The Fastest Mouse Clicker cross-platform edition (version 3 or higher) is a new generation auto-clicker for Windows, Linux, macOS, FreeBSD, OpenBSD. It is simply unlike any other auto-clicker you have ever tried - and the reason is buried deep in its engineering. Rather than slapping a GUI on a Python script or .NET framework like most competitors do, this app is a hand-crafted C++ application that talks directly to your operating system’s input hardware layer, using a patched cross-platform library called libuiohook. That means your clicks are injected at the same level as a real physical mouse, making them nearly impossible for games or applications like Minecraft, Roblox to detect or block.
The app separates its work across three specialized CPU threads - one for the interface, one for listening to your trigger key, and one dedicated to firing clicks as fast as the hardware allows - and uses lock-free atomic variables to keep them in sync with zero wasted time.
On Windows, libuiohook uses Win32 SendInput() API to achieve a verified 100,000 clicks per second by batching hundreds of input events into a single system call - a trick no other auto-clicker on the market has figured out.
The Fastest Mouse Clicker cross-platform edition extends the same codebase to Windows, Linux, macOS, FreeBSD, and OpenBSD from a single unified source, with a beautiful native-feeling Qt interface that looks perfect on everything from a 1080p laptop to a 4K workstation.
Built-in “humanization” options let you randomize both the timing and the exact pixel position of every click, so your automation looks indistinguishable from real human input to any game’s anti-cheat system.
The Fastest Mouse Clicker cross-platform edition ships as a fully static binary with zero external dependencies - no .NET runtime, no Python, no DLLs - just download and run. It is completely free, fully open source under GPLv3, contains absolutely no ads or telemetry, and has been trusted by over a million downloads across its entire lifetime.
Whether you are a gamer who needs an edge in Roblox or Minecraft, a QA engineer automating UI testing, a researcher stress-testing web applications, or simply someone who needs to reduce repetitive strain on their hands, this tool delivers at a level of technical supremacy that is genuinely rare in free software.
