Liberate your Lab
Do you want to spend your time doing science or programming?
To host an online study from scratch, you’d need to learn around four different programming languages. Is that the best use of your time?
No?
But that doesn’t mean you have to give up and resign yourself to underpowered lab studies with 20 participants (half of whom don’t show up). There is a better way!
With Gorilla Experiment Builder, you can set up your study using a powerful and easy-to-use graphical interface. Then gather more data from a more diverse participant pool — online, in the lab or both.
500 participants in a lunchbreak? Easy as pie!
Focus on the science, we do the programming.

“Gorilla allows us to efficiently collect large, diverse samples of participants that are often unfeasible to obtain in the lab. The task builder makes it possible to build pilot experiments within a short space of time, while also allowing the flexibility to implement more sophisticated psychophysical designs.”
Has your research ever been limited by either the tools you had available or your own programming skills? It’s frustrating isn’t it?
We believe that behavioural research is important. And we want to make it as easy to do quantitative research online as qualitative (survey) research.
With Gorilla, you no longer have to choose between the wrong tool for the job, or building it from scratch. You can have the best of both worlds with our powerful and customisable tools.
Or our Code Editor for when you really have to code from scratch but don’t want to manage your own server and database.
And you can rest assured that your data is safe, secure and compliant with university Information Security and IRB requirements.
Gorilla is made for experimental psychologists by experimental psychologists and software engineers so that you get powerful, easy-to-use, reliable tools.
The right tool for everyone, the right tool for you. Easy enough for students — powerful enough for research.

“I love Gorilla as experiment builder software so much that we’re transitioning our in-lab studies to this too.”
Support. On Tap.
How many hours of your life do you want to spend staring at unanswered questions on lonely forums?
It doesn’t have to be like this. Your time is important. You deserve better.
That’s why our friendly, fast and highly trained support team is always just a message away. And we go above and beyond to support the wider practice of online research, not just the technical implementation of your study.
We make sure that you never get stuck in your research:
- Astonishingly good support documents
- Weekly live onboarding and advanced webinars
- Gorilla Academy
- The friendly and well-moderated Gorilla Community that helps each other out
- The webinar series Gorilla Presents, where behavioural scientists meet to share cutting-edge methods
- And we also sponsor the yearly conference BeOnline, which brings together the smartest behaviourial researchers in the world

Online vs lab-based behavioral research: Letting go of the illusion of control
Some researchers have resisted the move to online research over the last few years, but the COVID crisis has forced many to switch to online methods. However, one question keeps coming up: “Jo, is there a good way to monitor the…
How Online Experiments Are Opening New Opportunities for Behavioural Economists
Picking a wine in a restaurant can be a nightmare, even if there are just three to choose from. Do you opt for the cheapest one, which sounds dependable? Or the mid-priced one that apparently goes with your food better? Or the most…
COVID19 was the push I needed to take my research online
Good science needs properly powered studies. Ten years into the replication crisis, we know this more than ever. Behavioural science can’t progress while we have serious doubts about the generalisability of our findings. We know part of…
Top three considerations to maximise data quality in behavioural experiments
Are you confident your online experiment will get you the data quality you need? Check out these top three considerations when piloting your study. At BeOnline 2020 Emily Breeze gave an insightful talk about piloting research. An often…

First year psychology undergrads at a poster session. They’re in small groups and presenting a small research project that they’ve created and recruited participants for. They’ve even interpreted the data that an R script has extracted…
Timing performance of online experiments
Are you curious about the timing accuracy of your online experiments? Online stimulus and response timing is good enough for a wide range of behavioural research. However, there are some quirky combinations to watch out for. We also make…
