The 9 best Real User Monitoring tools: A comparison report

| 11 min. (2176 words)

What is Real User Monitoring?

Real User Monitoring (RUM) provides visibility into the performance experience of live users interacting with your web, mobile, or single-page apps.

RUM tools emerged to bridge the gap between application performance metrics and the impact on real people. These days, user experience is increasingly factored into the development process, but that still doesn’t stop slowdowns. JavaScript on the front-end can be unpredictable, and complex user environments can create all sorts of performance problems and significantly impact your bottom line. After all, poor software quality costs US businesses $2.08 trillion annually, and the stakes are only getting higher.

RUM tools increase visibility and help teams pinpoint issues that might have otherwise flown under the radar. Ultimately, this means the business can deliver faster digital experiences and achieve objectives. After all, performant software is profitable software.

This guide will lay out the basics of RUM, while helping you zero in on the best tool for your specific situation.

Why Real User Monitoring?

To deliver the best UX, developers need performance insights at the code level. They also need to know which users are affected by issues to replicate the problem and solve it faster. Google is also pushing these tools withthe addition of Core Web Vitals (CWV) to their well-established Web Vitals initiative. Each of these new metrics represents a critical aspect of the user experience: content loading speed, interactivity, and visual stability. Google has now added Core Web Vitals to their search algorithm as a ranking factor, and is actively encouraging developers to enlist a real user monitoring tool to measure and optimize Core Web Vitals scores. (To learn more about Core Web Vitals and the role of RUM, see our whitepaper).

Benefits of a Real User Monitoring tool

  • Easily identify poor front-end performance impacting end-users
  • Analyze trends in application performance
  • Measure the impact of performance optimizations you’ve made
  • Understand user behavior in your application
  • Understand the impact that poor performance has on the user experience

How does RUM work?

RUM tools collect data directly from a user’s browser and send it to a centralized dashboard.

Usually, RUM tools use a lightweight SDK to capture performance and usage information when your application is running on an end-user’s browser or device. They send this data to a centralized display, providing it in helpful graphs and charts, so you can dig into performance insights about your application and devise strategies to resolve issues.

Selecting the right RUM solution

If you’re in the market for a RUM solution, here are some questions to keep in mind as you begin narrowing down your options:

  • What are your objectives with a performance monitoring solution?
  • Who are the different stakeholders using the tool? How do their needs/wants differ?
  • How well integrated is the solution with other core tools your team is using?
  • How easy is it to use?
  • What is the installation process like?
  • How do the solutions differ at each price point?
  • Does the solution support both your current situation, along with potential future requirements? To help you start your search, let’s compare nine leading RUM tools.

Deploy a user experience monitoring tool today for better digital experiences

If you’re going to invest significant time and resources in building applications, you also need to take steps to ensure they work as designed, that your users have consistently good experiences and that your Core Web Vitals (CWV) are up to standard. Otherwise, you’ll end up creating a product that merely frustrates users and impedes your business objectives.

The good news is that there’s an easy way to know if your applications are working. With real user monitoring tools, you can see your apps through the eyes of your end user. You have peace of mind, knowing that your app is working exactly as intended - and if not, that you can take immediate steps to rectify the situation.

Real user monitoring gives developers visibility into the performance of applications at the code level. Although the above tools offer slightly different features, they’re all designed to do just that.

Now, we might be biased, but we believe Raygun offers one of the most data-rich, powerful and valuable RUM solutions on the market. Find out for yourself with a free 14-day trial.
