OP Clicker is the popular shorthand for OP Auto Clicker — a free, open-source Windows auto clicker with 100+ CPS, 1ms precision intervals, a global hotkey, and fixed-position clicking. No installer. No ads. No bundleware.
OP Clicker is the widely used shorthand name for OP Auto Clicker, the free open-source auto clicker for Windows available at opauto-clicker.com. The full product name is OP Auto Clicker, but gamers and PC users commonly call it that for short. It runs as a portable 512 KB .exe file — no installer, no admin rights required — and supports left, right, and middle click at speeds up to 100+ clicks per second with intervals as precise as 1 ms. The app works on Windows 7, 8, 10, and 11 (32-bit and 64-bit). The default hotkey is F6: press once to start clicking in any window, press again to stop. It can follow your cursor or lock to a fixed (x, y) screen coordinate so it always targets the same pixel. Settings save between sessions automatically. The tool is completely free, open source under the MIT license, contains zero bundleware, and never connects to the internet.
The name "OP Clicker" comes from the gaming community, where "OP" stands for overpowered — a term players use when something is significantly stronger than everything else in its category. It earned that reputation by delivering 100+ CPS and 1ms precision entirely for free, with no installer and no strings attached, in a 512 KB file that runs on any Windows PC from Windows 7 onward. Most competing free auto clickers cap out at 20–30 CPS, require full installers, or bundle third-party software. This one does none of that.
This page covers everything: setup, the best settings for games and automation, and how it compares to other options. Whether you found it by searching "OP Clicker" or the full name, you are in the right place.
Six features that make the OP Clicker the standard free auto clicker on Windows.
At maximum speed, the app fires over 100 clicks per second — far beyond what any human hand can achieve and ahead of most paid alternatives. Set the interval to 1ms for peak performance.
Lock to any (x, y) pixel coordinate on screen. The clicker hits that exact spot regardless of where your cursor moves — ideal for idle game buttons, shop tiles, and accessibility use.
The OP Clicker hotkey works from any application. Press F6 to start, press again to stop — even while minimised to the system tray. Fully remappable to any key or combination.

The download is a single 512 KB .exe — nothing else. No offer screens, no toolbars, no third-party software. What you download is what you run.
Set it to fire exactly N clicks and stop automatically. Useful for buying items in bulk, timed test passes, or any workflow where you need a precise number of clicks.
From download to first click in under five minutes.
Get the 512 KB .exe from the download page. No installer required — the file runs directly from anywhere on your PC, including a USB drive.
Double-click to run it. If Windows SmartScreen warns you, click More info then Run anyway — the app is signed and VirusTotal-clean.
Choose Left, Right, or Middle click. Set Single or Double click mode. Most use cases need Left + Single.
Type a number and unit (ms, s, min, hr). 100 ms = 10 CPS. 10 ms = 100 CPS. The app accepts values down to 1 ms.
Leave on Cursor to follow your mouse, or switch to Fixed location and click Pick location to lock it to a specific screen pixel.
Switch to your target window and press F6. It starts firing immediately. Press F6 again from any app to stop. Settings save automatically for next time.

Less-obvious features worth knowing.
Set the Repeat field to a number instead of infinite. It fires exactly that many clicks and stops — useful for buying items in bulk or running a fixed test sequence.
Press Ctrl + S to save the current interval, click type, and position as the default. Next launch, the app opens with those settings already loaded.
Click the Hotkey field and press any key to rebind. F1–F12, numpad keys, and modifier combos all work. If F6 conflicts with your game, rebind to F8 or F10.
Some games block input from non-elevated processes. Right-click the OP Clicker .exe and choose Run as administrator if the hotkey stops working inside a game window.
