Magpie is a framework for building psychological online experiments that run in the participants' browser.

Magpie is composed of these parts:

  1. a server-side part that allows managing and configuring experiments and stores experiment results; and
  2. a client-side part based on Vue.js that runs in the participant's browser and provides:
    • a technical and conceptual framework for building experiments; and
    • a catalogue of components that can be used in experiments.

You can use the same server instance for running multiple experiments.

Vue.js enables building a web application out of small self-contained components, that you can re-use and share with other people.

Features

Some features of magpie include:

  • Declarative: Define your experiments in an easily extendable, HTML-based language (the Vue.js templating language)
  • Easy to use: There are many built-in screens to use for quickly building simple and advanced experiments
  • Composable: Build custom behavior by picking from and combining a wide range of components, built-in and external (any Vue-compatible library is supported)
  • Interactive: Allow participants to interact with each other with support for interactive experiments built in
