FourthParty is an open-source platform for measuring dynamic web content. Unlike many previous web measurement tools FourthParty is built on a production web browser, Mozilla Firefox, lending it the ability to:
  • monitor realistic interactions with web applications,
  • crowdsource data from actual users,
  • take advantage of existing browser extensions and automation tools, and
  • run on just about every modern desktop operating system.
FourthParty is fast, modular, and already generating research results. Get started measuring the web!
