Hi Toshi,
Since 2022, VPixx Technologies has offered a product called Pack&Go, which does exactly what you are describing.
Researchers can upload MATLAB/Psychtoolbox experiments to the Pack&Go scientist portal, test and generate participation links to distribute for remote testing.
VPixx uses state-of-the-art servers to host research experiments, so as long as you participants have a stable internet connection you can stream your experiment to their browser and collect responses.
It's a great way to reach a wider participant pool, and collect a great deal of data quickly.
Hosting experiments is free. Pack&Go uses a credit system, so you only pay for data collection sessions. You can find out more here: https://vpixx.com/products/labmaestro-packngo/
