Dr Suzanna Forwood

Senior Lecturer, Anglia Ruskin University

"I use Gorilla to undertake novel research in behavioural health. I can use Qualtrics for surveys, but Gorilla opens up a wider range of behavioural tasks incuding randomised trials and reaction time behaviour. It is easy to set-up a task for participants to complete at home over the internet, so I can use it to collect useful behavioural data from participants across the UK. I launched a study recently, went to lunch and came back to 400 participant responses."

Your Research. Unconstrained.


Configure your experiment and deploy it to the world instantly. With access to a planetful of online participants ready to take part, you can collect your data in a fraction of the time it would take in the lab.


Say goodbye to underpowered studies. Gorilla enables you to recruit far larger participant numbers, so you can be sure that you're seeing real effects.


Stop being WEIRD. Need more diverse participants? Or looking to study a specific demographic? Use Gorilla's seamless integration with recruitment services such as Prolific, MTurk and SONA to reach diverse or specific populations and meet your recruitment goals.

Dr Punit Shah

Lecturer, University of Bath

"I use Gorilla in my research on typical and atypical social abilities. This combines experimental tasks and questionnaire measures, in a way that is not possible using other platforms. I found the platform intuitive, easily to learn, but also very powerful. And I have also been extremely impressed with the enthusiasm and (personalized) support from the Gorilla Team, and believe the platform has potential to be the market leader in online experimentation, both in and outside of academic settings!"

Who is using Gorilla?

Dr Kirsty Graham

Research Associate, University of York

"I was awarded a grant to use Gorilla for an experiment on the human understanding of great ape gestures. As someone who is more used to studying our furry great ape cousins in the wild, the move to studying humans was made easier by Gorilla’s user–friendly platform and incredibly responsive support staff. We all love that Gorilla™ is hosting an experiment about great apes! The response has been overwhelming – the experiment was picked up by BBC Radio 4 and has spread through social media - so that we’re now at over 15,000 participants! It’s been a wonderful experience, and I can’t wait to get into analysing all that data."
