PsychoPy is an open source software package written in the Python programming language primarily for use in neuroscience and experimental psychology research.[2][3] Developed initially as a Python library and then as an application with a graphical interface, it now also supports JavaScript outputs to run studies online and on mobile devices. Unlike most packages, it provides users with a choice of interface - they can generate experiments by writing Python scripts, use a graphical interface that will generate a script for them, or combine both methods. Its platform independence is achieved through use of the wxPython widget library for the application and OpenGL for graphics calls. It is also capable of generating and delivering auditory stimuli.

The project was initially supported only by volunteer code and forum contributions alongside grants from The Royal Society, The University of Nottingham, Wellcome Trust, and BBSRC project.[3] A 2018 grant from the Wellcome Trust allowed for hiring of a full-time staff.[4]

According to its usage statistics page, Psychopy was launched on more than 20,000 different computers in November, 2018, and has gained relative usage by month every year since its initial release in 2003.[5]
