This program provides users with a rapid and reliable means to compute gray-body factors for massless fields with spin \\(s = 0, 1/2, 1, 2\\) in modes specified by the angular quantum number \\(l\\), given a black hole metric and the associated parameter values. $\\tt GrayHawk$ is preloaded with seven different black hole metrics, offering immediate applicability to a variety of theoretical models. Additionally, its modular structure allows users to extend its functionality easily by incorporating alternative metrics or configurations. This versatility makes $\\tt GrayHawk$ a powerful and adaptable resource for researchers studying black hole physics and Hawking radiation.
