User Testimonials

I’m very impressed with dynaTrace AJAX Edition’s ability to get at the underlying “magic” that happens inside a browser: page rendering, DOM method execution, browser events, and page layout calculation. Much of this information is completely hidden from developers and I’ve never seen it so easily collected into a single tool. Huge kudos to dynaTrace for revealing this information and especially so for making it happen in Internet Explorer."

John Resig, Creator of jQuery and author of Pro JavaScript Techniques

When it comes to analyzing your JavaScript code to find what's causing performance issues, dynaTrace Ajax Edition has the information to pinpoint the high-level area all the way down to the actual line of code that needs to be improved. I recommend you give it a test run and add it to your performance tool kit."

Steve Souders, author of High Performance Web Sites

Dynatrace Ajax is a very detailed lower level tool that not only shows the waterfall of components downloads but also the rendering time, CPU consumption, JavaScript parsing and execution. The screenshot above is just the tip of the iceberg of the tool's plethora of views and insights. It's highly recommended."

If there was a Nobel peace prize for software, I'd nominate @dynaTrace to receive it. It's that big of a deal"

dynaTrace AJAX Edition. It’s by far the best browser profiling tool out there – and it’s free!"

Patrick Lightbody, creator of Selenium Remote Control and co-creator of Struts 2

Having used this tool with clients I can say that this is exactly what the performance community has been waiting for. We see in our work that client/browser processing is a significant issue on many pages/sites (up to 4-5s on a page download). In fact, on some pages, client processing is taking 50-80% of the total page time and impacting the customer experience (locking and scrolling the page etc.) Using Dynatrace Ajax Edition to drill down into what is happening in the JS framework is EXTREMELY useful. Even my most technical customers are blown away. Great stuff guys!"

dynaTrace AJAX Edition gave us exactly the kind of analysis we have been needing for a while now. Using its AJAX transaction view we quickly discovered that a particular JavaScript function was re-rendering the page several times because a prototype sorting algorithm was being called in a loop. It would have been hard if not impossible to find the problem without it."

dynaTrace AJAX Edition is the best tool I’ve ever seen in this space. It feels like a Christmas present."

Andrew Espinosa, Principle Engineer, Monster.com

Kudos to you and your wonderful product! The DOM method "getElementById" did slow down the page loading and I've changed the logic to avoid calling it many times. After changing the AJAX mechanism the UI reacts considerably faster. Other tools we have used are too coarse-grained and don’t help much for performance tuning."

Robin Shine, System Architect, PMEase QuickBuild

Troubleshooting a JavaScript map application was really difficult. Firebug helped us to some extend, but drilling and filtering in profiled data would have been really great. dynaTrace AJAX Edition has those features! By navigating through HotSpots, checking the timeline and PurePaths connected to the server we were able to solve bugs, quirks and design, resulting in a superfast map app."
