Easy Multiplayer Interactive Experiments in the Browser
Empirica is the one method that provides enough flexibility to build any experiment while still being accessible and helpful to the researcher.
While Node.js and React.js are powerful tools, and you could build sophisticated experiments with them, Empirica makes building and managing your experiments much easier.
Notably, Empirica provides an Admin Panel that allows you to manage the conditions of your experiments (Treatments and Factors) and which Games are running, collecting data, or waiting for players.
Empirica does the heavy lifting in managing games, player connections, game life cycles, and more.
