JATOS at a glance:

  • Run studies on your own server. This means that you keep complete control over who can access your result data. (It's NSA-safe!)
  • It’s GUI-based, so there's no need to use the terminal to talk to your server.
  • Run your own, tailor-made studies, easily written in HTML / JavaScript / CSS (you will need some basic scripting skills).
  • Run group studies.
  • Connect to the Amazon Mechanical Turk (MTurk) marketplace to recruit participants.
  • Manage workers, to e.g. make sure that each participant does your study only once.
  • Export/Import studies to facilitate exchange with other researchers.
  • It's open-source and free to use.
  • It's very easy to Get started!
