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:
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
There are 3 different tooling tiers available to purchase: (1), (2) and (3)
(1) Questionnaire Builder Only - IDEAL SURVEY TOOL
(2) Task Builder + (1) - IDEAL FOR PSYCHOLOGY DEPARTMENTS
(3) Premium Tools + (1) and (2) - IDEAL FOR SITE WIDE SUBSCRIPTIONS
