Looking for Frontend Monitoring Tools? Well, here is the list of Top 10 Frontend Monitoring Tools in 2021.
Monitoring the performance of an application is not a strange concept to most developers. At one point or another, we’ve all had to do some performance debugging of our own. Usually, it happens when there’s a big issue affecting the user’s experience or cost implications. Only then do we make time to look at how the app performs in different scenarios.
Of course, there are different parts of the application that you can, and should, monitor separately. Most people split an app between frontend and backend and to save time, I’ll do the same. This article will focus on frontend performance monitoring and the tools you can use to do it. Below I reviewed some of the *best frontend performance monitoring SaaS to help you get started.
But first things first.
What Is Frontend Application Monitoring?
Frontend monitoring is the process to track and maintain the health of the presentation layer of your applications. It’s basically everything that a user would interact with, from the content and menu to APIs and other client-facing components.
Application performance monitoring, or APM, focuses on what users experience rather than the communication between server and client. While both are worth keeping an eye on, understanding how the users interact with your application is crucial in delivering a good experience, which leads me to my next point.
With help of Frontend Monitoring Tools, you can monitor your apps easily and in detail.
Is Frontend Monitoring Important?
Absolutely! We use many different frontend monitoring tools and techniques to monitor our backend, databases, infrastructure, and frontend shouldn’t be any different. As the complexity of our websites and applications increases, the monitoring needs are going up too.
Twenty years ago, you might have gotten away with just pinging your server a couple of times a day. Today that’s nowhere near enough. Any downtime or degradation of the performance of your website can have severe consequences.
Now, let’s begin…!!
Sentry tells when your application is crashing or going too slow and how the application is performing, enabling you to drill down into the areas that require your attention. Instead of addressing the error, you would address the issue that would have eventually led to the error. We use this tool for monitoring Vuexy Vuejs Admin template Vuexy Vuejs admin template.
The Performance view lets you understand how many transactions are getting triggered, how long they take and show you an Apdex score, which, as I mentioned earlier, is the ratio of both tolerable and satisfactory response times compared to all the response times.
While Sentry has support for server-side programming languages it lacks a server-specific logs integration. It does allow you to drill down on different transactions and see a breakdown of all the resources associated with them. This is not a deal-breaker for most. But if you are looking for an end-to-end monitoring solution, this one might leave you wanting more.
Pricing: 30-day Free trial, Paid plans are from $29 to $2120/month depending on the number of errors monitored, transactions, and the size of the field attached to those errors.
- Easy installation
- Uses Google’s Web vitals to provide details on performance
- Transaction tracing
Sematext Cloud is another good frontend monitoring tool needs. It offers a wide array of tools to help you monitor your performance, availability, debug errors, and keep a close eye on your infrastructure while you are at it.
The synthetic monitoring tool allows you to create complex monitors for all your resources. Also, Each resource can be pinged from multiple locations with a frequency of 10 minutes up to an hour. This will report back on your website speed, error rates, SSL certificates, API availability, and more.
Besides, with the addition of Sematext Experience, Sematext is the go-to tool for you whenever you need reports on the actual experience and satisfaction of your users while providing critical pieces of information as to how your website or application is performing in different locations, devices, or different connection speeds.
One of the major differentiators of Sematext is that besides the two products created focused on frontend performance monitoring, it also has Sematext Logs. This comes in handy when you are trying to debug the different performance issues and errors you might encounter.
Price: 14-day trial, $9/month for Sematext Experience, $29/month for Synthetics

Azure Application Insights comes as a feature of Azure Monitor provided by Microsoft Azure. It is extensible using the SDK or using the Application Insights Agent.
This tool can monitor the live application and detect performance anomalies with request rates, response times, and failure rates. Using the aggregated statistics and the stack traces provided, the developers can also analyze the server and browser exceptions reported.
Azure Monitor include:
- Detect and diagnose issues across applications and dependencies with Application Insights.
- Correlate infrastructure issues with VM insights and Container insights.
- Drill into your monitoring data with Log Analytics for troubleshooting and deep diagnostics.

With Rollbar, errors will be automatically logged as tickets in tools like Jira by setting up automated issue tracking, assigning to owners directly within Rollbar.
Rollbar’s real-time feed of errors enables the developers to address the critical errors affecting key customers occurring at low initial frequencies, which are otherwise difficult to detect.
Rollbar provides AI-assisted workflows which enable the developer to take immediate action on errors before they impact users. It presents data like the number of customers affected by the error, the type of platforms or browsers affected, and whether similar errors have occurred before or if a solution already exists.
Besides, Rollbar automatically starts identifying the recent deployment, which can be the reason behind the error to source code, stack trace, and the commits. This enables the developer to identify and view the differences quickly.
The automation-grade grouping feature automatically groups similar errors to reduce noise. The grouping rules can be easily customized, or errors can be manually merged to keep the alerts relevant.
