Monitoring a web application using a browser

While working on their projects, we repeatedly came up against the problem of the need for additional opportunities for monitoring our product. That is, besides the standard monitoring of load or availability to the server, I wanted to be able to continuously monitor and validate the interface of elements, forms, content, and other components. In other words, we needed a tool that would allow us to find out about the problems that have appeared and solve them before they are noticed by users.

We have created a service - qabot.net - which solves the problem and we think it may be useful for others. In general, the process consists in the automation of Selenium (Selenium2 + WebDriver) test cases that were created using Selenium IDE. At this stage, only Selenium IDE is supported, but if the service will be in demand, we will add other options for adding tests.

I would like to know your opinions and comments on this matter. Does this service make sense to you?
