Nexis began as a fork of Stacer, a popular Linux system optimizer created by oguzhaninan. After the original project went inactive in 2020, development continued here — porting to Qt 6 and C++17, adding native macOS support, GPU monitoring, a hardware info panel, kiosk mode, and fixing 38+ bugs inherited from the upstream codebase.
As the feature-set diverged, the project was rebranded to reflect that it had become something new. Stacer laid the foundation; Nexis is where it goes from here.
