Boomerang is a JavaScript library that measures web page performance characteristics from real end users' browsers and beacons the results back to a server. It is embedded in web pages and initialized with a single init() call to collect timing and user experience metrics.

Use cases

  • measure real user page load times
  • collect web performance metrics from browsers
  • monitor frontend performance in production
  • send performance beacons to an analytics backend
  • track user-perceived browsing experience

When to choose

  • you need real user monitoring (RUM) data from actual visitors
  • you want a mature, self-hosted performance beaconing library
  • you need detailed page timing metrics without heavy dependencies

When to avoid

  • you need synthetic or lab-based performance testing instead of real-user data
  • you want a modern actively developed RUM solution with vendor support
  • your project requires a permissively simple licensing setup, since the license is nonstandard
