DecLimiter

A free alternative to NetLimiter on Windows.

Installation

1. Compile DecLimiter from source or get an exe from releases

git clone https://github.com/dec4234/DecLimiter

cargo build --release

2. Install Windows Packet Filter

Usage

There are 2 provided ways to limit the speed of a process.

Selection List

1. Run the .exe file as an adminstrator
2. Select a process from the list
3. Set a download speed

CLI

-p, --pid = The process id of the process you want to control
-d, --download = Set the maximum download speed of the process (Optional)
-u, --upload = Set the maximum upload speed of the process (Optional)
-g, --garbage-collect = Set the garbage collection delay in seconds [Default: 60]

Limitations

• Currently only works on Windows
• Currently only supports limiting download speed
• Selection list shows all processes, not just the ones that actually use the network card
• Each instance of DecLimiter currently can only handle 1 process

Todo

• Fix limits not updating
• Completely remove scroll on limit input

Long term

• Implement a way to set different limits for different network interfaces
• Backend that works on mac and linux
