Facio is a free GUI for computational chemistry softwares (TINKER, MSMS, Firefly, Gamess, MOPAC and Gaussian).

It will be helpful to your study and research on theoretical chemistry.

Current Version  :  25.1.2  (released on July 17, 2023)

For Mac OS X (10.6 or later) and upto macOS 10.14 Mojave,

Windows

you can run 32-bit ver. with Wine (stable 5.0)
