Seeing is believing.

Learn what Gorilla can do for you and your research in three minutes.

Pro­gram­ming in Gorilla

While Gorilla is a tools-first plat­form, you can easily enhance and extend its capa­bil­i­ties with your own JavaScript code. You can still use the experiment tree, task builder, ques­tion­naire tool, and the rest of the Gorilla ecosys­tem, and only write the code you need.

Code Editor

Program your own tasks in the Code Editor. You can import third-party libraries to build your own task from scratch, or alter­na­tive­ly import tasks built in other frame­works (e.g. jsPsych and PsychoJS).

Task Builder Scripting

The Task Builder allows you to add your own scripts to augment its behav­iour. You can imple­ment complex coun­ter­bal­anc­ing or rewrite the spread­sheet at runtime to pick from a subset of stimuli, while still ben­e­fit­ing from the editing tools that the Task Builder offers.

Ques­tion­naire Scripting

The Questin­naire Builder allows you to add your own scripts to cus­tomise or enhance your questionnaires.

Pro­fes­sion­al Quality

Version Control

Each set of changes you make is stored as a stand­alone version, so you can save a working copy of a task or experiment before trying out some­thing new.


The Gorilla Team is on hand to fix prob­lems and answer ques­tions. We also do regular video guides, have exten­sive, search­able doc­u­men­ta­tion, and are avail­able for demos, work­shops and consultancy.


Gorilla uses modern browser fea­tures to ensure timing is as accu­rate as pos­si­ble. Details about Goril­la’s approach to timing are detailed in this article

Fully Hosted

Gorilla is pro­fes­sion­al­ly hosted on Microsoft Azure with servers and data­bas­es located with the EU (Repub­lic of Ireland). It is con­fig­ured to scale dynam­i­cal­ly, handle sudden bursts of traffic, and is auto­mat­i­cal­ly backed up.


Gorilla uses up-to-date cryp­tog­ra­phy, end-to-end SSL and real­time data­base encryp­tion to ensure that your work is secure and meets ethical requirements.


Caul­dron, the company behind Gorilla, has years of expe­ri­ence working with researchers and uni­ver­si­ties. We are fully incor­po­rat­ed in the UK and fully insured in com­pli­ance with Uni­ver­si­ty regulations.
