The z-Tree program was initially developed at the University of Zurich by Urs Fischbacher. Now, it is a joint project of the University of Zurich.
In z-Tree, you can define and conduct experiments. You can program a broad range of experiments with z-Tree, including public goods games, structured bargaining experiments, posted-offer markets or double auctions. The programming of z-Tree requires a certain amount of experience. There after, the effort required for conducting experiments is minimal: An experimenter with some experience in z-Tree can program a public goods game in less than an hour and a double auction in less than a day.
