Real Browser Playback

Real Browser Playback

AlertSite monitors your websites and web applications at the real browser level, where all the dynamic components of your applications come together. Real-browser monitors collect additional metrics that reflect web page load time from the user’s point of view, such as the time when the browser starts rendering the page. These metrics help you understand what your website users are actually experiencing in real time, and not just the network activities that are happening in the background.

Create Monitors in a Few Clicks

Deploying AlertSite and creating monitors is intuitive and almost instantaneous. Provide URLs to create availability monitors or use our web recorder DejaClick to create sophisticated transaction monitors. Select browsers, devices and record complex user transactions in real time. Turn the recorded script into monitors and immediately start seeing value. Even reuse functional tests from API testing tools like ReadyAPI and SoapUI to create advanced API monitors.
