ClickRun: A 606-Star Mouse Auto-Clicker, and Yes, It Works for Gaming Too

I’ll be honest — auto-clickers always felt a bit “sketchy” to me. The ones I knew were crude-looking, ad-riddled, and probably got you banned from games. Then I stumbled across ClickRun on GitHub: open-source, written in pure C, 606 stars. That’s not huge, but in this niche category, it actually means something.

Project Background

ClickRun comes from GitHub user InJeCTrL. The name is about as straightforward as it gets: Click + Run. Written in C, the entire project is extremely lightweight — the core code is maybe a hundred lines. No explicit open-source license is listed, but the code is public, so you can basically treat it as free software.

Its positioning is simple: a clean, ad-free, customizable mouse auto-clicker. No fancy UI, no bloat.

Core Features

Customizable Click Interval

You can precisely set the delay between clicks, from a few milliseconds to several seconds. I tested it and got it down to 1 millisecond — though whether it actually hits that rate depends on OS scheduling. At least the option is there.

Hotkey Toggle

There’s a default shortcut (usually an F-key or a custom combo) to start and stop clicking. This matters — you need a way to shut it off when your mouse starts going haywire, otherwise you’re hunting for the power cord.

Background Operation

The program has no window; it sits in the system tray and stays out of your way. That’s a plus for me — I can’t stand tools that park themselves on top of everything.

Minimal Resource Usage

Being written in C, its memory footprint is basically negligible. I ran it on an old laptop with 8GB RAM and could barely see it in Task Manager.

Real-World Use Cases

I tested three scenarios:

Scenario 1: Web Form Bulk Selection

Some internal system needed me to check dozens of checkboxes. By hand? Finger-cramping territory. With ClickRun? Done in 20 seconds. Honestly this is like “RPA 101” — except RPA tools are hundreds of megabytes, and ClickRun is a few dozen kilobytes.

Scenario 2: Game Automation

This one needs a careful disclaimer. Some idle games or resource-collection loops do work with ClickRun. But — and this is a big but — many online games have anti-cheat detection, and third-party clicking tools can get your account banned. I only tested it on single-player games, zero issues. For online games? Weigh the risk yourself.

Scenario 3: Stress Testing

I used it to hammer a button during a demo to see if the frontend would hold up. Mostly for laughs, but it was more reliable than manually clicking like a maniac.

Quick Start

ClickRun doesn’t come as an installer; it’s distributed as source:

# Clone the repo
git clone https://github.com/InJeCTrL/ClickRun.git
cd ClickRun

# Compile (Windows + MinGW example)
gcc -o ClickRun main.c

# Run
./ClickRun.exe

Or if you’re using Visual Studio, create a new C project and paste the code in. The project is so simple it doesn’t even have a Makefile.

For configuration, you currently adjust interval timing and hotkeys by editing macro definitions in the source. That’s not the friendliest experience — a config file, even a simple .txt, would be a welcome addition.

Pros and Cons

Pros:

• Extremely lightweight; native C implementation with negligible resource use
• No ads, no popups, no background shenanigans
• Code is simple and transparent — you can modify the logic yourself
• Open source, so no worrying about embedded malware

Cons:

• No GUI; configuration requires editing code
• Single-purpose; only clicks, no drag, scroll, or other mouse actions
• No record-and-replay; can’t script complex click sequences
• Windows-only (uses Win32 API)

Comparison with Similar Tools

Tool	Size	UI	Feature Richness	Open Source
ClickRun	Tiny	None	Low	Yes
GS Auto Clicker	Small	Yes	Medium	No
OP Auto Clicker	Small	Yes	Medium-High	No
AutoHotkey	Medium	Script-based	Very High	Yes

If you just want a plain auto-clicker, ClickRun gets the job done. But if you need recorded macros or complex logic, AutoHotkey is the real solution. ClickRun’s niche is “I only need clicking, nothing else.”

Who Should Use It

• Office workers who need to bulk-click through web forms
• Single-player gamers who want some idle automation
• New developers learning Win32 API mouse simulation (the code is short and teachable)
• Anyone wary of closed-source third-party software

Conclusion

ClickRun won’t change the world, but it solves a small, specific problem well. Those 606 stars mean at least a few hundred people found it useful. My take: if you need mouse auto-clicking and don’t want to install sketchy software, this project is worth the two minutes it takes to compile.

Of course, if the author added config file support and a minimal GUI, the audience would grow significantly. But then it might just become another GS Auto Clicker — and sometimes simplicity is the point.
