How to add a site to the accessibility monitoring service — comparison of free systems

Site monitoring is needed to obtain regular information about the status of a web resource. If some kind of error or server crash occurs, you will immediately know about it thanks to monitoring services.

Why do we need to check the availability of sites

If you do not add a site to monitoring accessibility, you risk losing your customers due to a non-working resource. The reputation will be damaged, and if an advertising campaign was launched, then you will also lose the money invested.

There are many such systems, so consider the most common options among webmasters.


Host-tracker has a user-friendly interface and easy registration. The site monitoring service is free for one month and notifies of errors by mail. To configure, follow the link and specify your mail address, which is convenient for receiving notifications and a hyperlink to the site: the system checks the site in the free version every 30 minutes, and offers to choose the format of notifications convenient for you: sms, email, Skype, Hangout, or voice message.

In addition to checking the availability of the site, the system will inform you if your domain or IP address is in the DNSBL blacklist, it will help stop Adwords company in case of unavailability of the resource, check the expiration date and much more. As a result, you can generate a comprehensive report within the system itself. The free version of the program is valid for 30 days.

You build your own tariff plan at the end of the 15-day period. This is convenient, as you buy only the necessary and sufficient functionality for you, and not the entire package of services.


Uptimerobot is completely free, which is certainly its advantage. Go to the main page and start monitoring:

Fill in all the fields to configure monitoring. Pay attention to the frequency indicator. The frequency determines how often the system will knock on the site and check its response code. Do not set the frequency too high, as the server may not be able to withstand the load and the site will simply "fall".

Consult with programmers. Usually, a frequency of 5 minutes is sufficient, unless every second is expensive for the site.

Comparison table

In addition to the main emphasis on monitoring site availability, the services offer auxiliary tools or advanced options for receiving notifications. The main results are concentrated in the table:
Comparison of availability monitoring systems
Uptimerobot offers monitoring and statistics reporting, advanced notifications, API integration, and completely free access. Other systems offer only limited access with the subsequent purchase of a tariff. Host-tracker allows you to check:

  • DNSBL blacklists;
  • domain and SSL certificate;
  • site speed and download options.

An important function of the service is Adwords Management is that it automatically suspends advertising companies, which helps to avoid losses.

Other systems from the list do not offer this. Naturally, you will receive notification of errors on the site. The minimum cost of the service is $9.92.

Monitis, in comparison with others, in addition to monitoring availability and integration with the API, has an advantage in the tariff, which you can set b yourself. That is, select only the functionality that you need. Instead, you will need to install special software on your computer.

Pingdom is doing serious analytical work. In addition to the fact that you receive a notification about the inaccessibility of the site, you will be able to analyze the reasons. The system also monitors user behavior in real time. The tariff price starts from $9.95.


There are enough offers on the market to monitor site availability. We considered a small part of them in the article. The results were published in a general table.

To set up monitoring, you will need to register and create your project in the system.

As you can see from the table, the pricing policy of paid programs is not much different, but you can start with the free version. Notifications are sent by all systems, but some are ready to offer advanced notifications via social networks, call and more.

Most systems analyze the domain and server loading speed.

Basically, you do not need to install additional monitoring software. Conveniently, systems allow you to create a command that the system simultaneously notifies of an error.

Take advantage of test access and independently evaluate the merits of each program.
