I launched a study, went to lunch and came back to 400 participant responses

"Gorilla opens up a wide range of behavioural tasks including 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."

The interface is clean and easy to use, even for really complex designs

"The interface for building experiments is very clean and easy to use, even for really complex designs (e.g. counterbalancing, different components, branching based on performance in a given task, redirecting back to Prolific). I can't say enough good things about their support documentation for researchers; it's quite lovely"
