Best RUM Tools to Track and Analyze Web Performance

By Tek-Tools on September 2, 2020

Your website is at the forefront of your business, and a well-performing website can boost the overall user experience. Over time, however, websites have become more complex. It has become critical to test the performance of websites in real time to identify glitches early on and fix them before it’s too late. Manually doing this can be daunting, and this is where a performance monitoring tool can help.

Most web performance monitoring tools are classified into a) synthetic monitoring and b) real user monitoring (RUM). While synthetic monitoring offers an artificial lab-like environment for testing, real user monitoring gives real-time insights into how users are behaving on the website. RUM ensures continuous data collection and shows the actual performance of real users with the utmost precision.

What Is RUM?

Real user monitoring refers to monitoring the actual user interactions on your website. The primary goal of RUM is to highlight the performance bottlenecks faced by the users in real time so the technical team can fix issues and improve the end-user experience. In general, a RUM tool collects data continuously and gives a wealth of insights such as geographic traffic analysis, page response time, load time, a detailed performance breakdown of various elements on a webpage, performance of third-party scripts and resources, navigation paths, root cause analysis, and HTTP errors, among others.

This article explores some of the best RUM tools you can deploy to track and analyze the performance of your websites and web applications.

Uptrends RUM not only visualizes page speed times experienced by real users across the country but state or province-wise across the U.S., Canada, and Australia. It provides page load time metrics such as render duration, DOM duration, and page ready time. Additionally, Uptrends RUM compares page views against performance and helps you point out problematic webpages. In addition to its RUM solution, Uptrends offers a synthetic monitoring solution. Uptrends RUM offers a 30-day free trial, and the pricing starts at US$12.02 per month.


The RUM tools discussed here are straightforward to use. For deployment, they require embedding a lightweight JavaScript snippet on each webpage or application you want to monitor. Of all the RUM tools mentioned, SolarWinds Pingdom is most suitable for businesses of all sizes. In addition to RUM, Pingdom also offers synthetic monitoring over a single pane of glass. Though all these RUM tools offer similar features on the surface, the way they handle and retain data, their depth and breadth of functionality, their efficacy, and their integration with synthetic monitoring differ. As all these solutions come with short, free trials, you can test and evaluate whether a tool or solution satisfies your expectations. Having real user monitoring and synthetic monitoring from the same vendor can help correlate metrics better and augment your web performance monitoring strategy.
