PsychoPy is an open-source software for creating experiments in behavior science. It is written in Python for the most part and has been actively developed for years. Resent releases of PsychoPy add support for Python3, creating browser-based experiments and sharing experiments on the web. In addition, a new online service named Pavlovia was launched to support browser-based experiment and experiment sharing. This article introduces current status of these new features. PsychoPy now works with Python3 though some hardware incompatibility and bugs remain. Experiments composed of basic components of PsychoPy Builder can be performed on web browsers. Users can search and share experiments registered on Pavlovia if allowed by the owner.
