Product Description 

A unified platform for world-class social science data collection 

Gorilla is a powerful platform built by academics for academics, making it effortless to collect data from participants anywhere in the world, using questionnaires, complex cognitive and behavioural experiments, or simulated online shops, all without writing a single line of code.

With Gorilla: 

  • Psychologists can build sophisticated experiments through an intuitive drag‑and‑drop interface or simply adapt one of the hundreds of ready‑to‑use, standardised paradigms freely available
  • Marketers can create realistic simulated online shops or recreate social‑media environments to test the impact of targeted interventions
  • Economists can implement a wide range of decision‑making tasks, including classics like the prisoner's dilemma, to explore behavioural dynamics. And,
  • Sociologists can design rich, flexible questionnaires tailored to their research questions.
  • And more! We've also been used in linguistics, anthropology, education, primary health and many more departments 

Whatever you can imagine, you can test it with Gorilla. 

Trusted by researchers & lecturers worldwide 
Gorilla is used by researchers on every continent, apart from Antarctica (we're working on this) and has powered over 3,000 peer‑reviewed publications and tens of thousands of PhD, MSc, and undergraduate projects. Its flexibility and adaptability makes it suitable for cutting‑edge research, large‑scale teaching, and everything in between.

One Platform. Less friction. More research. 
By bringing questionnaires, experiments, and simulations together in a single environment, students and academics only need to learn one system. Training becomes faster, teaching becomes smoother, and research becomes more consistent across departments

Significant savings - in cost, time, and effort 
Gorilla reduces the administrative and financial overhead that comes with juggling multiple platforms. Instead of maintaining separate subscriptions for surveys, experiments, and cognitive and behavioural tasks, universities can consolidate everything into one flexible solution. Credits can be shared seamlessly across questionnaires and experimental paradigms, and departments no longer need to manage multiple suppliers or procurement processes. The result is a simpler, more efficient, and more sustainable approach to research across the social sciences
