Best Website Monitoring Tools

Last updated on 23 Feb, 2024 by App Sky Star

Website monitoring tools is the process of testing and verifying that end-users can interact with a website or web application as expected. Website monitoring is often used by businesses to ensure website uptime, performance, and functionality is as expected.

The website’s availability is a critical part of a business; we can’t stare at the monitor all the time.

Setting up a command center and monitoring team is feasible for a large organization to monitor their web applications uptime but not for small-medium businesses, non-profit organizations, or personal bloggers. Your website can go down for various reasons, including database down or hack.

Another common reason for website down can be a hosting provider, and that’s why you should always host your site with a reliable hosting provider. Any website owner or administrator needs to ensure proper alerting is in place, so you get notified when the website is not available.

I’ve listed the following tools, which will help you get notified in case your web URL goes down. Most of them offer a FREE plan, so pick the one you like.

However, if you are looking for an in-house solution, then you can try a PHP Server Monitor open source.

Website Monitoring Tools

1. Datadog 

Datadog lets you proactively monitor your API endpoints and send alerts based on predefined parameters. You’ll be able to break down network timings that will eventually help you get to the root cause of your issues faster.

You can incorporate Datadog tests straight in your CI pipeline to ensure early problem detection allowing you to evaluate the state of your production environment after each deployment and minimize downtime by eliminating errors before your users ever see them.

All your critical transactions can be monitored with Datadog Synthetics without writing a single line of code with the web recorder. En user screenshots and step-by-step waterfall visualizations are paired with an intelligent system that identifies elements even after you make changes to the UI which results in a lot fewer broken tests.

Pricing wise Datadog starts at $5 for every ten thousand tests run every month and it is specifically aimed at monitoring SLAs and SLs from locations around the world. Browser tests start at $12 for every thousand tests and allow you to record tests without code, self-maintaining intelligent tests, and screenshots for every step.

Key features:

  • Performs uptime and response time monitoring from several locations around the world.
  • Enables user-journey modeling to check for load errors, programming mistakes, and poor website design.
  • Enables website tests to be compiled through browser recording.
  • Uses AI methods to vary user journeys during test runs.
  • Tests are run through actual browsers for real-life user experience modeling.

2. New Relic

  • Cost: $12.50/mo (for businesses with more basic monitoring needs)
  • Premium: $25/mo (for businesses with more advanced monitoring needs)

There’s no limit to monitors and pricing is dependent on either the number of hosts or the environment size.

New Relic is a cloud-based software that helps users to track their website and application performances. Their technology is delivered in a software as a service (SaaS) model. The company is mostly known for its application performance monitoring (APM) abilities, but it also offers other services like infrastructure, browser, and synthetics monitoring, which you can combine with APM.

New Relic supports 8 languages: Ruby, PHP, Java, Microsoft.NET, Python, Node.js, C SDK, and Go. To start monitoring an application in one of these languages, you’ll need to install one of the above-mentioned agents.

Their APM monitoring will analyze your application’s performance like uptime and speed and send you error reports if any problems arise. New Relic includes database monitoring for metrics, filterable Error Analytics, and Traces. They also come with response time, throughput (requests per minute through the application), and error rates (percentage of errors over a set time period for your app).

New Relic is a strong monitoring tool, but it can be difficult to navigate between different services and how they work together, especially compared to other monitoring companies like StatusCake or Montastic. However, you can check out and try their services for free for 14 days without any commitment.


  • Full Support for Google’s Core Web Vitals
  • Custom dashboards
  • Advanced alerting systems
  • Integration with your favorite ticketing system

3. SolarWinds

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.


  • Pre Configured alerts and dashboards that speed up the setup process.
  • Synthetic monitoring solutions
  • A neat mobile application is available for free

4. Uptime Robot

  • Cost: $0 (including 50 monitors, 3 months of a log, 5-minute monitoring intervals)
  • Premium: $121/mo (including 1000 monitors, 24 months of logs, 1-minute monitoring intervals, and 160 SMS credits)

You can choose a Premium Plan which comes with anywhere between 50 to 10,000 monitors. Each plan comes with a higher number of SMS as well. The higher the number of monitors, the higher the cost.

If you’re looking for a completely free solution, Uptime Robot is a good place to start. It was launched in 2010 when its developers set out to create a free tool for everyone. They promise that it will continue to be free, with prices only added for any premium features they develop in the future.

This tool will check in with your site every five minutes and alert you if there’s any downtime. Although it works well, it lacks the larger operations you’ll see with premium options. For example, Uptime Robot has main monitoring in Dallas, USA, with a few others scattered throughout the world, but premium monitoring tools typically have 40-50 server locations to monitor and verify your site’s downtime.

When you sign up for a free account, you’ll also get three months of logs so you can keep an eye on how your site has changed over time. You can also monitor up to 50 websites for free.

Uptime Robot is a good tool available at no cost to you, even though some users complain about the limited features, such as no manual alert testing. You also won’t get page speed insights like with some paid website monitoring tools.


  • Advanced notifications will let you set certain prerequisites for your alerts. Eg: x errors in y minutes
  • Simple setup process
  • Heartbeat monitoring for intranet and cron jobs
  • SMS and email notifications are available

5. Freshping

Freshping by Freshworks lets you monitor 50 URLs from 10 locations worldwide with one minute of internal in FREE.

Freshping is an all-in-one site availability monitoring solution with the following features.

  • Multi-channel notification
  • Status page to announce real-time incident status to your users and customers
  • Multi-user login
  • Integrate with other services like Slack, Twilio, Freshdesk, Zaiper, etc. to get notified

Under the FREE plan, monitoring data is available for six months.

6. Pingdom

  • Cost: $15/mo (including 10 monitors, 50 SMS alerts)
  • Premium: $455/mo (including 400 monitors, 500 SMS alerts)

There are more options for choosing your monitoring frequency (up to 30,000 uptime checks) for more expensive pricing. Pingdom also offers an Enterprise plan which offers from 500,000 to 5 million pageviews a month. Moreover, there is a 30-day trial to check out their services.

If people can’t access your website at certain points throughout the day, then you’re losing sales and search engine rankings. Unfortunately, you can’t manually monitor your site’s uptime at all hours, and that’s where Pingdom’s tools come in handy.

Although Pingdom offers some free tools, such as a website speed test, where it shines is in its premium features. Pingdom can help you analyze your website’s uptime and performance by testing your site from servers across the world and alerting you if there’s an issue.

Pingdom also helps you improve user experience by delivering feedback from real users and analyzing performance factors such as website speed. They’ll also help you pinpoint any causes of problems to help you resolve them quickly.

Overall, it’s a powerful, reliable tool for smaller businesses on a budget, but some users complain that it puts little emphasis on mobile traffic, has unreliable SMS capabilities, and lacks monitoring servers in Asia-Pacific. We also use Pingdom to monitor the best hosting providers.


  • Detailed interfaces with user-friendly features
  • Instantaneous alerting system
  • Real user monitoring and synthetic monitoring
  • The mobile application makes up for the somewhat complicated setup
  • SMS and email notifications are available

8. Uptrends

Founded in 2007, Uptrends provides a variety of monitoring services, from standard website monitoring to real user monitoring. The company’s impressive client list includes big names like Microsoft, HP, Virgin, and Zendesk.

While the paid plans offer an extensive list of advanced features, you can find several free tools on the company’s website, including a free-forever website monitoring tool that will monitor your site from locations all over the world.

The free version will send you an email alert whenever there’s a problem – but not before your site has been tested from two different checkpoints, to prevent false alarms. You also get detailed data reports which you can export to PDF or Excel.

Key Features

  • Multi-browser monitoring: Uptrends offers “real browser monitoring,” which hits your website with the three major browsers to recreate your users’ experience. The Full Page Check feature hits every webpage and element on your website, and it’s got 200 worldwide checkpoints for true global performance monitoring.

9. Dynatrace

Dynatrace monitors the availability and performance of your internal resources with monitors from private elocution making it easy for you to understand how your users experience your website and apps by measuring and recording key metrics.

Dynatrace offers three types of synthetic monitors The first one is a single-URL browser monitor that acts as a simulated user visiting your app or website and can be configured to work from any of their available locations with a frequency of 5 or more minutes. The second one is Browser click paths that are similar to the single-URL act as a user but follow a path throughout your application. The third version is the HTTP monitor that is a simple HTTP request that can be customized and ran at various intervals.

The pricing for Dynatrace is simple as it starts at $11 for every ten thousand monitoring units. These can be either Real user monitoring, Session replay, and Synthetic Monitoring. Dynatrace also offers a free trial with no commitment.


  • Flexibility to utilize real-user monitoring, synthetic monitoring, and session replay
  • Built with privacy and security in mind to meet your GDPR requirements
  • Real-user monitoring for mobile, hybrid, and single-page applications with common analytics

10. Smartbear

Smartbear is amongst the most comprehensive tools for large-scale enterprises that wish to monitor almost every aspect of their online presence. Besides keeping a very close eye on your web application through a wide variety of tools that range from run-of-the-mill uptime and alerting solutions to some innovative monitoring options, Smartbear also checks up on your mobile applications, API status, and database health.

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.


  • Lots of third party integrations
  • An extensive list of resources and support material
  • Robust Reporting & Analytics

11. Host-tracker

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.

Key Features

  • Performance monitoring: HostTracker breaks down its performance measurements into DNS lookup time, connect time, “first-byte” time, and download time. This enables a granular view that makes it easy to spot specific bottlenecks.
  • Uptime monitoring: HostTracker’s “availability check” feature is similarly detailed and can be configured to check not only the website and server availability but also applications connected to your website as well as your database connections.
  • Alerts: Highly customizable alerts via your choice of email, voice message, SMS, Skype, Google Hangouts, or Viber. You can also set conditions and assignments for alerts to ensure that each team member gets only the appropriate ones.
  • Auto-pause Google Ads: HostTracker can automatically pause your AdWords campaign if your website is unavailable, and start it when the site is back up.

12. Versionista

Versionista is a simple yet powerful tool for monitoring web pages of static and dynamic websites. You can monitor web pages as well as documents like PDFs, like Visualping. What sets it apart is you can set filters to skip irrelevant content changes and manage and track changes in SEO to stay competitive in SERPs.

While creating a monitor, you can customize frequency, JavaScript support, proxy address, and more. What I like is it shows color code comparison to highlight changes and supports sending change alerts and detailed emails. Moreover, Versionista supports team collaboration, allowing admins to manage users and users to collaborate between them to support team projects.

Versionista’s plans start from $19/month for checking 20 URLs and performing 1860 browser crawls (checks) per month. If you need to add team members and require customizable reports, Versionista’s plans start from $139/month.


  • It automatically crawls and monitors your website.

  • You can collaborate with your organization team.

13. Distill.io

Distill.io is a featureful tool for monitoring web page changes. What makes it unique is its support for cloud as well as local monitors, unlike the above tools. Also, it supports automating steps like logging in, exporting data, using custom proxies, tracking changes in documents like PDF, and managing versions.

Distill.io’s plans start from $15/month for individual users with a 10-minute tracking interval in the cloud. If you are seeking an advanced plan, the Flexi plan starts from $80/month with a 2-minute tracking interval and flexible limits.

Uptime has a RUM tool that helps you deliver the best user experience by tracking users across different devices, locations, and connection types. The data collected will be displayed in easy-to-understand dashboards that will provide actionable data on how to fix the performance issues of your site.

While there is no free tier, Uptime does offer you a risk-free, 21-day trial across all their packages that should give you a taste of everything it has to offer.

While their basic package caters mostly to US customers, the more expensive ones do get multiple checks from worldwide locations and have a log history between 4 and 24 months depending on the tier.

23. Visualping


Visualping is among the best web page monitoring platforms available, which offers intuitive features fitted for both beginners as well as advanced users.

Visualping claims it is used by more than 1.5 million users worldwide performing 5 billion checks. Its features include performing checks from every 5 minutes to every week, checking for documents like PDFs, choosing screen configurations, configuring proxy settings, and alert options.

You can share a tracked page with friends or team members, visualize results as charts, send notifications to email or Slack, export data, and do a lot more.

PageCrawl.io’s plans start from $8/month for tracking 100 pages or URLs with a 15-minute tracking ability. If you are looking for an enterprise plan, it starts from $30/month for tracking 500 pages with a 5-minute page tracking ability.

26. OnWebChange


If you want to track exact information, OnWebChange can do it as simply as possible. Though it is not as powerful as Wachete some of its features even outstand the latter.

What got me stuck is its public tracker feature that lets you place a button on your site that helps your visitors track any page on your website.

Additionally, you use its ‘Change Report’ feature to share a public tracker with friends and coworkers and help you track changes conjointly. OnWebChange tracks change for various types of content like images, documents, PDFs, etc.

Another surprising feature is it creates an RSS feed to help you track the changes, unlike that of Wachete.

It allows three trackers for free and features multi-language support and a powerful change detection system with lots of customizable options. It can send mobile or email notifications in a single or digested form per your preference. Moreover, it sends emails to multiple persons, creates an email distribution list, and even notifies URL ‘Callback’, surprisingly.


* Track changes to any plain text files and online files.

* It checks changes every 5 minutes, 24×7 hours, and 365 days.

* You do not require to download any files or browser plugins.

* Share notifications with family, customers, and friends.

* Track changes to online files (PDFs, images, etc.) and any plain text files.

* Receive notification directly to your mobile.

* This online tool allows you to filter out the content you want.

27. ChangeTower


Using ChangeTower, you can monitor three addresses for free. It is a cloud-based, easily accessible tool that is capable of monitoring visual changes. You can track code updates, keywords and code changes, and visual changes made on a webpage.

That said, it helps automate your research work.

What I like is that one can also check a site’s availability and receive alerts on configured conditions. ChangeTower can notify you, or your team using real-time email notifications and allows you to see notifications stream and check out detections.

Also, you can check the changed data of three months in for free, and even export it to a spreadsheet.

Another interesting feature is it sends you a detailed report of content, snapshot, and HTML changes, helping you to easily understand the changes.

Some of its use cases include monitoring key compliance requirements, legal and corporate compliance info, or content (like product prices) on any website including that of your competitors.


* It provides keyword alerts.

* This tool provides notification for only significant changes in keywords and phrases.

* It alerts when your website page goes down and comes back online.

* You can monitor HTML code.

* It allows you to store time-based code snapshots.

28. Wachete

Montastic is another tool popular among webmasters seeking a free solution. Though it’s pretty basic, it is helpful for individuals and smaller businesses who are simply looking to be alerted when their site goes down. Unlike other providers on the list, Monastic doesn’t exactly have a dashboard – they keep it very basic and simple with only notifications when something goes wrong.

Montastic will check in on your site every 30 minutes, which isn’t necessarily great compared to the five-minute intervals offered by other free services, but you can upgrade to get more frequent intervals and URLs to monitor.

Montastic will email you both when your site goes down and when it comes back up. You’ll also be able to see keyword presence or absence verification on a web page; it gives support for any port number; and it features widgets for Mac, Windows, and Android.

What’s the Verdict? Which One Should We Pick?

There’s no way to say which website monitoring service is better than the others because it all depends on what your goals are with your website.

From our experience, the best free options would probably be StatusCake and Uptime Robot. They have enough flexibility/features and can monitor your site at 5-minute intervals. So if you’re just testing the waters and aren’t sure if you really need one, go ahead and try them out.

The most bang for the buck you’d probably get from DotCom-Monitor, but we love the Pingdom user interface more, so it’s completely up to you.

One thing is for sure – Premium website monitoring tools will offer more features and reliable data to help you improve your site. If you’re serious about website monitoring, establish a budget so you can take advantage of these tools.

We’re not saying that the free tools are bad, though. In fact, they’re great if you don’t need all the bells and whistles. You can start with one of the free tools mentioned here, and if you feel you need a look at the “bigger picture,” consider a premium plan for monitoring your site performance.
