Html Script is a totally free project for checking, comparing and validating some of the most useful metrics of websites. We do not have direct access to any of these websites' servers, DNS data or access their logs. Html Script project is based on some legal database sources and a statistical model which tries to involve user activities and responses to improve this large data source.
As you can see, web is growing really fast and that means more data to collect for us. We are improving our system from time to time not to fall back from this growth and apreciate our precious users for taking time and helping us even if it is a few-question-survey, that is a meaningful help for us and for other users searching true, safe, useful content.
