It’s not enough to build a website with a great design. You have to keep a watchful eye on it as well. But manual monitoring tasks like uptime and server status are time-consuming. It’s a much better idea to use website monitoring tools instead.
Website monitoring is a catch-all term that describes any online service that checks a website for its availability, function, speed, and performance. Most often, these monitoring services are set up then run independently, only alerting you when a problem arises.
The website monitoring tools market has experienced tremendous growth, with the global market valued at $4.13 billion in 2025 and projected to reach $9.04 billion by 2033, representing a compound annual growth rate (CAGR) of 10.2%. This growth is driven by businesses’ increasing dependence on digital platforms and the critical need to maintain optimal online performance.
In this guide, we’ll discuss:
- The main types of website monitoring software
- Why you should use website monitoring tools
- The 12 most popular website monitoring tools
Main Types of Website Monitoring Tools
There are a few key types of website monitoring software you should be aware of. Let’s spend a moment defining each.
- Server availability: This type of monitor can detect if certain servers are available, such as websites, external servers, databases, and mail. This includes what would be called “uptime” monitoring. It can also detect if more advanced services are available like DNS, FTP, and SSL.
- API monitoring: This is often used for keeping tabs on apps. Web service HTTPS, multistep API, and app transactions can be monitored this way. With the rise of microservices architecture in 2025, API monitoring has become even more critical for maintaining service reliability.
- Performance monitoring: This type of monitoring pertains to browser checks and full-page checks that report on how your website is performing overall and piece by piece. It’ll tell you if there are any issues with scripts, CSS, images, or timeouts. Modern performance monitoring now includes Core Web Vitals tracking, which directly impacts Google search rankings.
Why You Should Use Website Monitoring Software
Whether you opt to use a website traffic monitor, website analytic tools, or a more general performance monitor, one thing is for certain — there are several reasons to use these monitors in your day-to-day website operations.
Here are just a few of these reasons:
- Website monitoring software gives you an accurate indicator of how your website is performing.
- Website monitoring tools alert you of website downtime so you can resolve the issue quickly. This means fewer people are likely to attempt to visit your website while it’s down, so you can mitigate any potential revenue loss. Studies show that even one minute of downtime can cost e-commerce sites thousands in lost revenue.
- Website monitoring software gives you a heads-up of potential problems. You can see if certain pages on your site are loading slowly, if people aren’t scrolling down to your call to action, or if some aspect of your website is broken.
- Monitoring tools provide key performance metrics. Once installed, you’ll gain at-a-glance access to data about how every aspect of your website is faring, including the latest Core Web Vitals metrics that affect SEO performance.
- You can also use these tools to evaluate your hosting provider to ensure they live up to their promises. Most providers offer an uptime guarantee. Website monitoring software lets you see firsthand if that is the case.
- AI-powered insights: Modern website monitoring tools now integrate artificial intelligence and machine learning to provide predictive analytics, helping you identify potential issues before they impact users.
Now that you have a clear sense of what these tools do and why you should use them, let’s get to our list of the 12 top performance tools currently available.
