Synthetic monitoring has been a staple of performance testing for years now and it’s probably going to stay that way for quite some time. Also called proactive monitoring, this relatively simple way of keeping track of the performance of your website, and is your safest bet to ensure you can rise to your visitors’ expectations.
Synthetic monitoring tools run simulated user interactions on your website to provide detailed information on the performance of your applications, uptime, certificate issues, load times, APIs, and so much more. You can even have it set up to run complex requests that will result in a comprehensive testing of your critical business transactions.
That sounds awesome, but considering all the tools available in the market how do you know which one is right for your specific use case?
To help you get started, I’ve compared some of the best synthetic monitoring tools and software to test the performance of your website.
But first things first.
When Do You Need Synthetic Monitoring?
You’ll want to get synthetic monitoring as soon as possible, even before your website gets any visitors. Setting up synthetic monitoring before your website and app is released to the public is a great way to establish a benchmark for it. This data will make it easy for you to compare against your competition and identify the sections where you need more work.
Once your website or web app is ready, you’ll use synthetic monitoring to test out your scaling capabilities. On paper, you are always prepared to meet the requests of your users, but when it comes down to it, websites, especially new ones, are rarely up for the task.
After you are up and running, you’ll use synthetic monitoring to keep an eye out on your environment and alert you the second it goes belly up. Having an early warning system will help you reduce your MTTR (mean time to repair) and make sure you are fixing the issues even before your users get to see them.
Now, let’s look at some of the synthetic monitoring tools we’ve found are the best in their field.

How to Choose The Right Synthetic Monitoring Tool for Your Use Case?
As you might imagine, having a lot of options can be just as bad as having but a few. It begs the question of how do you pick one. The truth is that there’s no clear answer and it’s going to be mostly based on your particular needs. Here’s what you should consider when on the market for a synthetic monitoring solution:
- Do you want an open source tool or a SaaS?
- How many monitors would you like to run and how often?
- What type of budget do you have?
- Will you need additional services like a real user monitoring tool or log management software? It’s easy enough to focus on one product that solves your need but do debug your issues. You’ll probably need to get a solution for real user monitoring, log management, and infrastructure monitoring. This means that if you are using a single product solution, you’ll have to look somewhere else for these, having you spend more time and money on this.
- How many people in your organization will use the application? Some solutions will charge you for every extra seat at the table and the price can go exponentially higher if you happen to have large teams.
- How often do you plan on running your tests? How complex are they going to be?
- How many testing locations would you need and in what regions?
- Do you need to look behind a firewall or not?
One thing in particular I recommend you should pay special attention to – whether you’ll need additional services or not. For instance, if your use case requires log monitoring and infrastructure monitoring, the list will be significantly smaller. And this in particular is not a small task. Having the ability to see exactly the error that the server recorded when the issue was reported is going to save your team hours and hours of debugging.
How about RUM? Real user monitoring allows you to record the interactions of your actual users while synthetic monitoring will simulate them. It might not be obvious right now, but combining the two will remove all the blind spots that you might have if you choose to use just one without the other. We explained the full benefits in our article about real user monitoring vs synthetic monitoring, so make sure to check that one out as well.
All of these questions, among many others, will play a major role in how you choose the best synthetic tool to monitor and test your website.
Sematext Cloud was built with all of these in mind. You don’t have to choose just one of these products, you could have them all under one roof. Sematext has amazing infrastructure and log monitoring as well as a real monitoring solution which means you can have a complete overview of all your resources.
Getting started takes a couple of minutes and thanks to a 14-day free trial, you can take all of these great features for a test drive before you commit to anything. Try it and see for yourself!
What Solution Will You Use?
By now it should be painfully obvious that you need a synthetic monitoring solution to ensure the same top-notch experience for your users in China, the US, Europe, or any other corner of the world, regardless if it’s day or night.
Picking one tool over another requires a formula that cannot be universally applied to every company so it will come down to your individual needs. If you have small individual teams and you know that only one will use a particular solution it’s probably fine to get a single product solution. But more often than not, unless you already have an infrastructure monitoring tool that you are comfortable with, you’ll want to get both.
