The Com­plete Package

Study­ing complex behav­ior shouldn’t be complex. Our pow­er­ful and easy-to-use online tools allow you (and your team) to build exper­i­ments with minimal effort.

We’ve got you covered from simple ques­tion­naires and reac­tion-time tasks to complex multi-day train­ing studies and ran­dom­ized con­trolled trials.

Seam­less­ly inte­grat­ed with popular recruit­ment ser­vices, you can source a wide and diverse range of par­tic­i­pants to com­plete your study fast.

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.

“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!”

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.”
