Designed to support a wide range of research ideas, it can be used for projects that go beyond standard templates, including work that has not been built before. Its starter library features marketing research tools such as MaxDiff and choice-based conjoint, psychological tasks including Stroop, go/no-go, and random dot motion, and multiplayer activities such as poker and live word search. Researchers can also create social networking and online shopping simulations, financial experiments such as double-auction markets, classic game theory activities such as the prisoner’s dilemma, and surveys.

oTree reports that its platform has been used in more than 3,000 publications. For users who want to build without coding, the oTree AI Builder (OTAI) helps create research-grade apps to specific requirements. The platform also provides documentation, a forum, code samples, an FAQ, and access to its code through GitHub, giving researchers resources to develop and explore their projects
