Best Synthetic Monitoring Tools

Websites used to be simple. A few pages of text and images held on a Web host were easy to monitor. These days, things are a lot more complicated. Content delivery networks and caching servers hold copies of the same website on many different servers around the world to speed up delivery. Services, such as widgets or tracker libraries mean that content from other servers needs to be read into a web page as it is loading into a browser. Websites are no longer delivered from one single server.

Here is our list of the best synthetic monitoring tools:

Now that the successful delivery of a web page requires many connections to different servers in different places around the globe, there are a lot more things that can go wrong and prevent that page from loading. Monitoring a website yourself to see if it is available from your offices is not enough. You need to check that people all over the world can see your site.

Asking people you know in different countries to look at your website is a non-starter and you can’t expect the general public to contact you if your site isn’t available in a faraway place. So, you need a system that performs automated checks on your site from many locations.

Synthetics for websites

Human website checkers cost a lot of money. The only viable method to make sure your website is available everywhere is to use automatic processes driven by software. This is what synthetic monitoring does.

Synthetic monitors remove the need for real people to check on your site from different locations. They emulate the actions of users and report back on statuses. An automated process doesn’t accidentally miss out on checks or forget to write things down. Automated monitoring is free from human error.

There are three levels of synthetic monitors:

  • Uptime monitors
  • Response time monitors
  • Web transaction monitors

An uptime monitor just checks that your site is available. These checks are launched from several locations around the world and they occur repetitively. Some businesses set their uptime monitoring frequency at one minute, while others can work with five-minute intervals or even longer.

A response time monitor will report on how long important elements in a page took to load – these are also called load time monitors. This is because you don’t just need to know how long your web server took to reply to a request; you need to know how long it takes for the banner to appear and also elements such as images. It is important to know when the interactive features on a page, such as links, become active. Generally, uptime monitors work on websites, and response time monitors examine Web pages.

A Web transaction monitor is also known as a Web performance monitor or a Web application monitor. This checks on the elements in a page and makes sure they are working individually and as a suite. The proper way to make sure that a Web page works the way you expect it to is to get a real person to go through all of the utilities in your site, such as input forms or video players, and activate them. However, you don’t want to be reliant on members of the public to email you and tell you that an important part of the site is broken. This is because people won’t bother to do that, they will just move on to a rival site and buy its goods and services.

A Web transaction monitor implements a test script that runs through a sequence of actions on your live site to make sure that any users that arrive will be able to successfully complete an important task, such as ordering a product.

Synthetic monitoring modes

Some of the tasks that check on your live website can be done without actually loading any pages from it. For example, a system doesn’t need to load a page into a browser if it is just checking that the DNS entry for the site is correct or that the SSL certificate is valid. These synthetic monitoring services operate programmatically and are also known as API testers.

Uptime monitors in particular don’t need to get a full page from your site in order to report on its status.

Web transaction monitoring wouldn’t be thorough if a WebCrawler performed it. You can only get a proper user’s eye view of a site if it loads into a browser, so all Web transaction monitors are browser-based. Response time monitors are between these two scenarios because some elements can be tested just by examining the code for a Web page without actually having to render it. Others require the page to be loaded into a browser in order to measure its load time.

So, there are two modes of synthetics – API testing and browser-based tests. Browser-based tests are more expensive than API tests.

Synthetic monitoring frequency

Some factors of a web server’s performance are more vital than others. For example, if a Web server has gone offline, there is no point in launching a Web performance test. So, the different types of tests are performed at different frequencies. The optimal frequency for each type of test is:

  • Uptime monitoring: 1 minute
  • Response time monitoring: 5 minutes
  • Transaction monitoring: 15 minutes

Uptime monitoring is the cheapest form of website checker and so can be performed more frequently without breaking the bank. It is also the most fundamental test that you need. As transaction monitoring is the most expensive type of test, businesses with little money to spend will lengthen the frequency of those tests.

Web application testing

The automated methods built into synthetic monitoring are ideal for use with We application testing. Although there are many packages available to perform specialized security tests for applications under development, the fundamental need to ensure that applications work speedily and accurately also needs to be addressed.

While synthetic monitoring for live sites and applications is better if those tests can be launched from remote locations, efficiency tests for applications that are yet to be released need to be able to reach into your private environment. So, there has been a recent push in the field of synthetic monitoring to allow the testing messages to be set up with internal testing destinations.

Synthetic monitoring packages that can integrate with project management tools and bug trackers are particularly useful for integration in CI/CD pipelines.

The best synthetic monitoring tools

In this report, we look at synthetic monitoring services that offer uptime monitoring, response time monitoring, and Web transaction monitoring. Some services offer all three in a bundle, while others focus on just one category of synthetics. The common thread is that they will let you know when problems arise without you having to wait for visitor counts to drop in order to figure out that something is wrong.

Our methodology for selecting a synthetic monitoring system

We reviewed the market for synthetic monitoring tools and analyzed the options based on the following criteria:

  • Uptime and response time monitors
  • Alerts for unavailability or slow responses
  • Multiple test launch locations
  • Options for development testing
  • Root cause analysis
  • A free trial or a demo system that enables an assessment without paying
  • A system that offers value for money by providing comprehensive monitoring at a fair price

Using this set of criteria, we looked for a range of synthetic monitoring services that are offered by both cloud-based and on-premises solutions.

1. Datadog Synthetic Monitoring (FREE TRIAL)

Datadog Synthetic Monitoring

Datadog is a cloud service that monitors website performance from several locations around the world with synthetics. Uptime checks work with TCP requests, which enable them to check on DNS servers and SSL certificates at the same time. The service also includes an HTTP-based check to ensure that a web server is not only operating but that it can locate and deliver the pages of your site.

Key Features:

  • Cloud-Based: A SaaS package
  • Graphical Data Visualizations: Customizable screens
  • Live Performance Reports: Get notified when a site goes down
  • Development Testing: Record and play back a walkthrough
  • Option to Connect to Distributed Tracing: Code profiling is also available

Why do we recommend it?

Datadog Synthetic Monitoring offers two types of automated testing services: API-based tests and browser-based tests. The browser-based tests are considerably more expensive than the API tests. Each test type has different launch methods. The API service is a standard test, such as Ping, while the browser-based tests are recorded walk-throughs of a site.

Transaction monitoring with Datadog launches browser-based tests, following an action script. The results of each run are displayed as a waterfall graphic that makes the performance of each service that gets triggered by the action clearly. It is easy to see from this visualization which elements are slow and whether any services failed. Datadog also includes an automated transaction testing service that is based on AI machine learning. It explores all of the interactive elements in a page and tests them in combination.

The test launcher for the Synthetic Monitoring package lets you decide on the test launch location so you can track performance as seen by site visitors in different parts of the world. There is also an option to integrate synthetic testing into a CI/CD pipeline for DevOps environments.

Datadog is presented as a series of modules – of which the Synthetic Monitoring package is one – and complimentary units slot together to add greater value. For example, the Datadog Application Performance Monitor includes a distributed tracing function and a code profiler. These services fit together well with the Synthetic Monitoring package for businesses that need to check on the root cause of Web app performance impairment.

Who is it recommended for?

Given the big price difference between the two types of tests, you would use them in different ways. The API tests are usually set to run repeatedly as an availability monitoring service. The browser-based system is usually used to check interactive elements in a Web page before releasing it.


  • Response Time Monitoring: Includes details for page elements
  • DNS Server Testing: Records availability and response times
  • SSL Certificate and Domain Registration Monitoring: Warns when expiry approaches
  • A Choice of Test Types: API or browser-based
  • Tests Interactive Elements: Cycles through a list of possible inputs


  • No Self-Hosting Option: Only available on the cloud

A subscription for programmatic tests cost $5 per month per thousand test runs and browser-based test cost $12 per month per thousand. You can get an unlimited 14-day free trial of Datadog Synthetic Monitoring.


Datadog Synthetic Monitoring is our top pick for a synthetic monitoring tool because this package is very flexible offering a range of testing systems that include API automated checks and browser-based tests. You can operate the synthetic monitoring service from several hosted locations or set up your own private launch sites on cloud servers around the world or from within your own network. Use this package to test live websites or integrate into your CI/CD pipeline testing cycle for automated workflows. Add on the APM package to get root cause analysis services that include code profiling and distributed tracing for microservices.

Synthetic monitoring tools FAQs

What is synthetic monitoring tool?

Synthetic monitoring is implemented by tests rather than passive data gathering – this is why this form of system monitoring is called “active monitoring.” Synthetic monitoring services range from recursive Ping runs to more complicated services that operate through browsers. The main target of a synthetic monitoring system is a website to assess its performance with respect to response times and the first appearance of important features in each page. Options to look out for in synthetic monitoring services are the ability to launch tests from different locations around the world and confirmation tests before alerts are raised.

What is synthetic monitoring example?

Most frequently, synthetic monitoring tools are used to monitor the performance of websites. Some metrics that are specific to Web page delivery include the time it takes to load a page in a browser or the time until a key feature, such as the banner, an advert, or an image appears in a loading page. Synthetic monitoring tools for these metrics are usually run through actual Web browsers and some services give you a range of browsers to choose from. Mobile apps can also be tested with services that offer specific makes and models of devices to run tests from.

What is synthetic performance monitoring?

The most widely used type of synthetic performance monitoring is the availability test. This is performed with Ping on a loop so administrators can know immediately if a server fails to respond. Ping monitoring can be used to test the performance of a wide range of IT assets, not just Web servers. For example, a recursive Ping is often found at the core of many network performance monitors and it can also be used to test the availability of specific applications on a corporate application server or cloud platform. Ping can be used to test the connection to a target across the internet, so it is also often used to check on connection speeds to monitor the delivery of internet services. This is useful for SLA enforcement.
