KeysFX isnβt a clumsy web wrapper. It is a native Swift macOS binary built directly on Appleβs high-performance CoreAudio framework.
Go beyond simple clicks with high-fidelity weapon acoustics. Experience bolt cycling, receiver locks, and metallic gas piston motions tuned for tactical satisfaction.
Zero perceptible lag. Every sound triggers within fractions of a millisecond of your physical keycap making contact, matching natural audio-visual reflexes.
