Keynote Systems has released Mobile Web Perspective (MWP) 5.2 and Mobile Internet Testing Environment (MITE) 2.2, the latest versions of the company’s mobile performance-monitoring and content-testing products supporting advanced HTML5.

With an estimated 34 percent of the world's top 100 Web sites using HTML5, and the mobile device market of smartphones and tablets growing at an exponential rate, it is critical for mobile Web sites to close the performance gap with the desktop experience. MWP 5.2 and MITE 2.2 empower IT and Web operations professionals to set and achieve performance goals in order to provide a better mobile user experience. Using these solutions, enterprise customers can consistently monitor and optimize their mobile sites around the clock, based on devices, networks, and geographies.

Keynote Mobile Web Perspective (MWP) allows users to monitor the availability, response time, and quality of any mobile Web site from the Keynote global monitoring network. Complex use cases that combine navigating Web sites on a desktop or mobile device and sending/receiving SMS messages can be monitored using MWP. Companies can set instant alerts to quickly inform key members of the operations team who can then address issues and minimize their impact.

Keynote MITE is an advanced tool for testing and verifying mobile content. With MITE, mobile content developers and operations and QA teams can instantly verify if Web site content is correctly formatted and displayed across mobile devices using a built-in library of 2,000 devices and 12,000 devices profiles. MITE 2.2 is available as a free download at

New MWP 5.2 and MITE 2.2 Features

WebKit Browser: WebKit is a widely used mobile browser and is embedded in both iPhone’s iOS platform and Android phones. Keynote’s use of the actual WebKit browser enables accurate performance monitoring for mobile Web sites. Unlike Web browser solutions that attempt to emulate mobile browsing, Keynote MWP provides performance measurement data on HTML5 sites that is native and faithful to how smartphone users actually experience the mobile Web.

  • Touch Events: Mobile Web sites taking advantage of smartphone touchscreens allow end users to interact with content in ways generally not supported on the Web. With this release, MWP and MITE are both aware of touch events and provide Keynote customers with the ability to create scripts that mimic a human being actually performing gestures such as taps and swipes. Consequently, operations teams can now monitor the end user experience of tap and swipe gestures on today’s leading smartphones.

  • Global Infrastructure with Geo-location: The Geo-location API allows smartphones to take advantage of location aware services offered by mobile Web sites; examples include: downloading store locations on retail sites, finding restaurant lists on Yelp, checking-in on Facebook, seeing local ads on content sites and getting weather updates on Yahoo! With this release Keynote makes two new capabilities available:

    • Within MITE, mobile site operators now can specify different locations and test location-specific content by sending any GPS coordinates to the mobile Web site

    • Similarly, operators can use the Keynote global network to monitor local-specific content by specifying any GPS coordinates. Beyond being just city aware, Keynote mobile performance monitoring is now street aware. This is the latest in location-based performance monitoring for mobile Web sites that are taking advantage of the Geo-location API in HTML5.

  • HTML5’s Local Storage: Local storage is a new technique Web developers use to improve the mobile browsing experience. It allows for an entire mobile Web site to be downloaded to the smartphone for offline browsing and accelerates mobile sites by locally caching data that does not frequently change. With this release, Keynote MITE supports HTML5 local storage giving testers the ability to verify that an entire mobile site has indeed been downloaded for offline browsing.

Benefits of Keynote MWP and MITE

A number of teams across the enterprise benefit from Keynote’s mobile Web performance monitoring, content testing and verification including services.

IT and Web operations teams can:

  • Detect mobile Web site availability with Keynote MWP and track when minimum performance thresholds are not being met. Real time alarming notifies the first line teams of critical issues and helps them pinpoint the problem areas so they can quickly address issues, reducing the mean time to repair.

  • Use Keynote MITE to analyze Web content and verify that it works well with selected devices and locations. IT operations can triage potential performance and quality impacting issues and work with development teams to improve mobile Web site performance.

Online and mobile business managers can:

  • Gain insight into the performance of their mobile Web site from the perspective of their end users with Keynote MWP. Knowing performance relative to the competition and industry best practices allows the product and business manager to make strategic decisions on how much content to deliver up front, knowing that more content can result in slower loading times and a better user experience.

  • Use measurements from Keynote MWP to review service level reporting of the ongoing performance levels and, when called for, change strategic direction.
