addLEDs was created by independent developers as a utility to compensate for the lack of physical LEDs on modern keyboards. The program is written in C++ using the Windows API to ensure compatibility and performance. The first version was released in 2018 and has received periodic updates to improve stability and add features. The application is distributed as a portable executable with no installation required.
