CogBuild is a completely online solution for running behavioural experiments over the web. CogBuild includes user management, experiment management and data management, as well as an online experiment builder and experiment runner. With CogBuild, you can use an existing platform to get workers or participants in your experiments (such as the Amazon Mechanical Turk or Alkorm's P-Manage) and design and run them using CogBuild. CogBuild has a basic-tier flat subscription fee of $20USD per month per researcher, but there are other licensing options available (e.g., for whole departments or research labs). However, you can sign up as a trial user if you wish to try the product free first. The trial version includes all the functionality of the full version, but experiments are limited to 10 minutes in length.
