OP Auto Clicker is a free, open-source auto clicker for Windows. Up to 100 clicks per second with millisecond precision — custom intervals, hotkey toggles, fixed-position clicking — for gaming, productivity, and accessibility. No ads, no bundleware.
Built for power users — designed for everyone. Switch tabs to explore.
Three things separate OP Auto Clicker from every other free Windows auto clicker.
Most free auto clickers cap at 30–50 clicks per second because of how they handle Windows input. OP Auto Clicker calls the SendInput API directly with a 1-millisecond timer floor — that's how it sustains 100+ CPS without dropping clicks. Whether you're auto-mining in Minecraft, grinding pet eggs in Roblox, or stress-testing a UI, every click registers cleanly. Drift over a 60-second burst stays under 1%.
OP Auto Clicker is publicly available on GitHub. Anyone can read the code, build their own copy, or contribute fixes. Every release is digitally signed, scanned by VirusTotal across 70+ antivirus engines, and ships with a published SHA256 hash so you can verify exactly what you're running. No bundleware. No telemetry. No internet calls. Just an executable that does what it says, and nothing else.
OP Auto Clicker has been the go-to free Windows auto clicker for nearly a decade. The 512 KB portable .exe runs on Windows 7, 8, 10, and 11 without an installer, registry writes, or admin rights. F6 starts and stops it from any application — Minecraft, Roblox, Cookie Clicker, browser games, productivity apps. One tool, every use case.
From competitive PvP to office form-filling — built to feel invisible.
OP Auto Clicker is the most-downloaded auto clicker among Minecraft, Roblox, and idle-game players. It supports jitter-style 12–15 CPS for PvP, burst 25–50 CPS for Roblox clicker simulators, and slow 0.1 CPS for AFK reward collection. Pick a hotkey, lock to a fixed pixel, walk away. Configurable enough for serious players, simple enough that first-timers can be running in under a minute.
Single-player and casual servers permit auto-clicking; competitive servers (Hypixel, Mineplex) prohibit it. OP Auto Clicker sends standard Windows input events that look identical to real clicks — basic anti-cheats don't detect it, but advanced anti-cheats may flag any automation. Always check each game's terms before using competitively.
OP Auto Clicker is widely used for UI regression testing, bulk form submission, smoke-test loops, and the kind of repetitive desktop workflow that quietly burns hours. Set the interval in milliseconds, seconds, minutes, or hours. Set a click count limit. Lock to a fixed pixel coordinate. Run from a USB drive on locked-down work PCs (no installer, no admin rights). Close it when done — nothing left in the registry, nothing on disk except the .exe you downloaded.
OP Auto Clicker is used worldwide by people with limited mobility, RSI, or chronic wrist pain. Configure a comfortable interval once, bind it to a key your hand can reach without strain, and let the software click for you. The whole app is keyboard-driven if you need it to be: tab between fields, enter to confirm, F6 (or any remapped key) to toggle. Open source means accessibility tools won't be paywalled or removed in a future "premium tier" — OP Auto Clicker is free, forever.
Drag the slider — watch OP Auto Clicker click at any interval from 1 millisecond to 2 seconds.
From gaming grind to repetitive office tasks — automation made simple.
Skip the grind. OP Auto Clicker is loved by Minecraft, Roblox, and idle game players for repetitive in-game actions.
Automate the boring stuff. Use OP Auto Clicker for software testing, form filling, and any repetitive desktop workflow.
Reduce repetitive strain. Users with limited mobility rely on OP Auto Clicker for hands-off interaction with Windows.
