When users look for ultra-fast clicking, they generally choose between two categories: Software Clickers

Over the next week, she quietly owned the building’s HVAC, coffee machine, and the CEO’s biometric safe. She programmed a nanosecond burst to mimic a single valid fingerprint read—the sensor couldn’t distinguish the avalanche of signals from a real ridge touch.

These tools require high-level permissions to simulate inputs, which can be misused.

: Often cited for having an "extreme" mode that attempts to bypass some software delays to reach higher CPS (Clicks Per Second). Risks of Extreme Autoclickers

If you see a claim like that, it’s a scam. Even the fastest mechanical or optical mouse switch has a minimum debounce time of several milliseconds. A 1 ns click would mean the switch opens and closes faster than the speed of light over a few centimetres – impossible. Software‑only autoclickers cannot exceed the USB polling rate (max 8000 clicks per second, i.e., 125 µs per click).

for extremely short delays (<200 µs)
