13. Host-tracker [paid]
Pricing: $14 – $99/month
Simple by design, Host-tracker is intended for site admins that want to monitor their servers availability as well as the transactions between server and client. It mainly focuses on key metrics like page errors, database connection problems, and network issues.
The pricing schema is simple enough, composed of three separate tiers, each with its own unique set of features and capabilities. It’s worth mentioning that at first glance the price for their basic tier seems high compared to the other products mentioned here but I believe that the packed features of the more expensive tiers make up for this.
One thing Host-tracker is missing compared to the other options listed in this list is the ability to monitor real users. It’s not a big deal if what you are trying to do is focus on the server’s resources but for websites that deal with a lot of users like online publications or e-commerce stores, RUM is going to be crucial to providing the best experience possible for your users.
There’s no free tier but every signup comes with a free, no credit card required, a 30-day trial where you can test all the features of the product, risk-free.

Last but not least, Smartbear has an impressive 340 testing nodes around the world, which is at least double what most competitors have. Keep in mind that Smartbear does not have a real user monitoring product so if you are looking for that particular feature, you’ll have to look elsewhere.
While being one of the top dogs on the block when it comes to online monitoring, this comes with a hefty price. Prices for their packages range from $199 to a staggering $1999 a month. Let me put it this way, the cheapest option costs more per month than most competitors in a year.
Features:
- Lots of third party integrations
- An extensive list of resources and support material
- Robust Reporting & Analytics
15. SolarWinds Web Performance Monitor [paid]
Pricing: Starts at $1999/year
Solarwinds has been at the forefront of the monitoring space for years and in this time they’ve developed a large number of services to help their customers better understand what’s going on behind the curtains but that experience comes at a great(er) cost.
Web performance monitoring is just part of their impressive software ecosystem, and as it stands today, is one of the most complete solutions for DevOps in the world. While nobody can deny their experience or the value that their app brings to customers, the price tag can still be a tough pill to swallow, especially when you look at smaller competitors that charge a fraction of the price for, what it seems, a very similar product.
It’s important to note that while the list of features includes Endpoint detection and response, network device monitoring and even a cool mobile app that helps you keep tabs on your web app anywhere in the world, Solarwinds does not have a RUM solution available. It’s worth noting that they do record every step of the transactions between the server and user which will provide some insight into their experience.
Their Web performance monitoring tool offers detailed load-time metrics from multiple locations across the world that record all browser-based transactions while providing key insights into what happens under the hood of your website.
Features:
- Pre Configured alerts and dashboards that speed up the setup process.
- Synthetic monitoring solutions
- A neat mobile application is available for free
How to Choose the Best Website Performance Monitoring Tool?
The list could have gone on for quite some time but in an effort to save some of your precious time I made the list go up to only 10. This is not to say there aren’t any other tools out there, but I believe that the ones mentioned above are the best mix of features and price.
Now here comes the big question, how do you pick one. While there is no simple answer, there are few key criteria you should be looking for.
URL Monitoring Frequency
A website monitoring service works by pinging your website every X minutes to make sure the site is up and all your resources load correctly. The smaller the X the better.
Unless you are using some third parties that have inconsistent performance that needs to be monitored constantly, 5 minutes is plenty enough.
Integrated server and log monitoring
While not every website monitoring service comes with a server and log monitoring solutions, I believe it to be extremely important as CPU usage, memory utilization and disk space can directly impact the users’ experience on the website or application.
Keep this aspect in mind as it will help you identify the strengths and weaknesses of your website and perhaps be able to tackle issues before they become a big problem.
Synthetic and Real User Monitoring
For the best possible user experience, using a combination of both synthetic and real user monitoring is probably going to be the safest bet. While both methods have their own strong points, using just one of them will end up creating some blind spots when it comes to your user’s satisfaction. Read more about this in our RUM vs. Synthetic Monitoring blog post.
It’s a common practice to have both of these features available from the same vendor but keep in mind this does not mean they all do. It’s really important to take some time to figure out the type of service you are going to offer and if you’ll end up needing an all-round monitoring solution, I’d strongly suggest looking at a vendor that can provide you with both. Having data from both synthetic and real user monitoring compiled in the same place will give you a better point of view and have you react to problems faster and more efficiently. To help you get started, we gathered the best RUM solutions and also compared the top API monitoring tools available today.
Testing locations
Testing your website locally will result in a totally different experience than having it run in a country across the world. This is why having worldwide testing nodes is important as it will let you figure out what parts of the website are struggling to deliver the same top tier experience to your global audience.
Learn more about how locations affect your website performance from What is network latency and how to reduce it to improve website performance.
Support for multiple browsers
If you ever had the “pleasure” of dealing with multiple websites you are probably familiar with the many incompatibilities between them. A script running smoothly on Safari might work differently or not at all on Internet Explorer or vice versa. Having tests for multiple browsers will let you know what the users experience while using your services.
Solid alerting capabilities
You’ll need to be able to set up alerts for different sections and functions throughout your website and if done correctly, they will act as an invaluable early warning system that will make sure you know exactly when things are about to go belly up. A lot of services fire false positives or have issues relaying the alert so using a service that allows you to set up alerts via multiple channels should be a priority.
Price
Just like anything else out there, the price will have a big impact on your decision. While more features usually equal a bigger price, with website monitoring solutions big prices don’t necessarily equal more features.
It’s important to have a clear understanding of the needs of your website so that you can make the right decision before picking a service especially since some of them will only accept yearly contracts and the price tag can sometimes be around $2000.
Conclusion
At the end of the day, choosing a website performance monitoring tool is going to be based on your particular needs – check out our Guide to alerting and monitoring to learn how. There are more than enough options out there to choose from if I may be so bold as to make a suggestion, you should take the time to understand which metrics are important to your website and based on those, filter out the tools that allow you to carefully track and monitor them. Go further and correlate those metrics with UX metrics to get insight into all the metrics that could impact your users and, ultimately, your business. If your monitoring needs are not that complex yet, I suggest you at least keep an eye on page load times by using a website performance and speed testing tool. You’d be surprised how simply improving this metric can go a long way with your customers.
