For long time I had a need to track changes on a web map. I tried different services for website content monitoring and surprisingly none of them worked on that specific web application (it was a government website with land ownership rights). It was approximately 2 years before I finally decided to build DeepWebMonitor to solve this issue.
During all this time I checked the map manually, missed some important changes because I can't check regularly. Also I saw a lot of other usecases where I could use a service for regular content monitoring and this idea of building the tool myself started to appear in my mind more frequently. I work as a freelancer and occasionally completed a project related to Chrome browser automation. It appeared to me that I had all the knowledge needed to build website change monitoring tool using Google Chrome and it will be capable to monitor any kind of web app or web form I need.
So in Jan 2019 I started to code the new project which I named - DeepWebMonitor. I'm not sure that the name is great but for anyone who knows the concept of Deep Web it should be obvious what it does. Deep Web is a part of global web that is hidden behind various forms and only available after some interaction with website. I hope that it will be as useful to other people as it is to me. Anyway I had a lot of fun implementing the project and now when it is fully functional and works I use it to track dozens of websites.
