Introduction to Online Experiments using PsychoPy

New JsPsych plugin for draw in canvas and cursor position tracking

Open-source research platform for reproducible online behavioral experiments in virtual societies.

Computerized adaptive testing (CAT) for Python

R client for the JATOS REST API: credentials in the OS keyring, incremental downloads, analysis-ready data

catR implementation in JavaScript. Provides Computerized Adaptive Testing (CAT) based on Item Response Theory (IRT) for psychological online experiments.

Robust 'massively scaleable' cloud-based online experiment runner. But with minimal hosting fees.

Run markerless motion-tracking experiments online. MediaPipe in the browser, Firebase for data, Python for analysis. Beginner-friendly, no build step.

Online adaptive experiment on human exploration behavior · JavaScript · jsPsych · decision-making

Cross-platform software for testing spatial memory via object placement and judgement of relative direction tasks in the lab and online

CUPED variance reduction for A/B tests - reach statistical power with fewer samples using pre-experiment data. NumPy/SciPy only, zero heavy dependencies.

Standard Extensions for Variant Experiment Server

Analyses of interpersonal coordination in memory and perception through a Dallinger-based online dyadic experiment.

Development repo for @jspsych-contrib/extension-humancheck: a jsPsych extension that flags likely bots and AI agents in online experiments, without blocking anyone.
