psiTurk v3 has been released! See the migration guide here.

psiTurk v3 does not support the psiturk ad server. If you still need the psiTurk ad server, use psiTurk v2.3.12, and remove all HTML comments from your ad.html file. Versions less than v2.3.12 will not be able to post HITs due to a change implemented by the psiturk ad server's hosting provider. You can upgrade to psiturk v2.3.12 by running pip install --upgrade psiturk=2.3.12.

Python versions

  • Psiturk v2 supports python 2 and python 3. Documentation for psiturk v2 is available here
  • Psiturk v3 is python 3 only. Documentation available here


Check out a clone of this repo, and install it into your local environment for testing (consider installing into a virtualenv):

git clone
pip install -e psiTurk

A test suite can be run using pytest from within the base directory of psiturk.
