Auto Clicker Open is a lightweight, open-source clicking tool that runs offline with zero tracking or telemetry. Download once, use forever — the source code is on GitHub under MIT license, so you know exactly what it does.

Set the exact coordinates or follow your cursor. Choose your click speed from 1 click per minute to 1000 clicks per second, and pick which mouse button to use. It works while your game window is in focus — no background clicking required.
You don't need to pay, sign up, or trust your clicks to someone's server.
No subscription, no trial period that expires, no 'freemium' limits. Download and use it as much as you want. The source code is published under MIT — you can even modify it yourself if you need to.
The app runs entirely offline. It doesn't phone home, doesn't show banner ads, and doesn't require you to log in or give an email. What you see is what you get.
One portable .exe under 1MB. Download the zip, unzip, and click the app. No installer, no system dependencies, no bloat.
It's on GitHub for anyone to inspect. If you're worried about what it does, you can compile it yourself from source using the .NET SDK.
No configuration needed — the defaults work out of the box.
Auto Clicker Open gives you the same features without the subscription, the ads, or the privacy trade-off.

Yes. The source code is public on GitHub under MIT license, so you can review exactly what it does. No hidden features, no malware, no tracking.
That depends on the game's terms of service. Some games allow it, others don't. Check your game's rules before you use any clicking tool.
No — Auto Clicker Open works globally and clicks the coordinates you set, whether the window is focused or not. This is actually useful for AFK games where you want to click while reading or working.
No to both. Just download the .exe, run it, and start clicking. No setup, no login, no email required.
Technically you can set it to any interval, but clicking much faster than 1000 per second won't work reliably on most systems due to hardware limits.
The full source is on GitHub. You can download it, change it, and build your own version using the .NET SDK — no permission needed.
No. Auto Clicker Open is free under MIT license and will always be free. Updates, if any, will be posted on GitHub.
It's free, portable, and ready to use the moment you unzip it — no ads, no account, no surprises.
