The Com­plete Package

Study­ing com­plex behav­iour should­n’t be com­plex. Our pow­er­ful and easy to use online tools allow you to build exper­i­ments with min­i­mal effort.

From sim­ple ques­tion­naires and reac­tion-time tasks to com­plex multi-day train­ing stud­ies and ran­domised con­trolled tri­als, we’ve got you covered.

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.”

Power Your Science

Take your research out of the lab and into the real world

From pro­to­types and pilots to repli­ca­tions and roll-outs, Gorilla is with you every step of the way.

The Gorilla Team offer per­son­al sup­port, on-demand con­sul­tan­cy and world-class bespoke devel­op­ment, with years of expe­ri­ence pro­vid­ing tech­ni­cal sup­port to some of the world’s lead­ing researchers.
